General Questions
1Which standard defines the IP protection classes and what does IP68 mean?
The IP numbering is part of the protection class system defined by the IEC 60529 standard. It specifies the degree of protection that enclosures offer against the ingress of dust and liquids. IP68 means complete protection against the ingress of dust and protection against permanent immersion in water up to 1 meter.
2Are BBC Cellpack insulating tapes (e.g. No. 128) suitable for repairing cables and wires?
As long as only the cable sheath (outer plastic) is damaged, the insulating tape is suitable as temporary protection. Sealing against moisture is not guaranteed. However, if the basic insulation is also damaged, simple insulating tape is no longer sufficient. The use of a gel, cast resin or shrink sleeve is then recommended. The same applies to damage to the conductor.
3Are shrink, cast resin or gel sleeves from BBC Cellpack suitable for use in potentially explosive atmospheres?
There is currently no approval for use in potentially explosive atmospheres.
4Does BBC Cellpack have special approvals for the shipbuilding industry?
No, BBC Cellpack does not have any approvals for the shipbuilding industry.
5Does BBC Cellpack have special approvals for switchgear construction?
BBC Cellpack has numerous approvals for low and medium voltage products. It is recommended to request special approvals, as the list of approvals is updated regularly.
6Which components of BBC Cellpack contain the SVHC substance lead?
Products that contain the SVHC (Substance of Very High Concern) substance lead in a concentration greater than 0.1% must be registered in the SCIP database at the ECHA (European Chemicals Agency). At BBC Cellpack, products from the joining technology with aluminum and/or copper alloys are affected. They may continue to be sold and are not subject to a sales ban. This is confirmed by the current ROHS and REACH declaration of conformity, which can be downloaded from the online product catalog for each product.
7Can fittings be used under the influence of swimming pool water?
Water in swimming pools contains a certain concentration of chlorine. Without a test with the actual chlorine content or the composition of the water (e.g. thermal water), use is not approved.
8Are BBC Cellpack cable accessories resistant to seawater?
Cast resin and shrink fittings are generally resistant to seawater. However, these are not tested directly with the usual test standards.
9Can the cable accessories be used in drinking water applications?
There is no drinking water approval for the fittings from BBC Cellpack.
10Is maintenance work mandatory for BBC Cellpack's low and medium-voltage accessories?
No maintenance intervals are prescribed by BBC Cellpack. Depending on the application, however, the fittings should be checked by the operator and cleaned of deposits (sand, salts or other soiling) if necessary.
11Why is personal protective equipment necessary when preparing earth cables?
When preparing a ground cable, carcinogenic gases and vapors are produced when the bitumen layer is flamed and toxic lead dust is produced when the oxide layer of the lead sheath is broken open. For this reason, PPE (personal protective equipment) must be worn when preparing the ground cable, for example article 447993 "PPE/(G+H+3Pb)". When using PPE, a risk assessment should be carried out beforehand.
12What does FE180 and E90 mean?
The designation FE180 refers to the behavior of cables in the event of fire and indicates insulation integrity for 180 minutes in accordance with DIN VDE 0472 Part 814.
The designation E90 means functional integrity for 90 minutes of a complete system (e.g. cable) in the event of fire in accordance with DIN 4102 Part 12 and is verified by test certificates.
The designation E90 means functional integrity for 90 minutes of a complete system (e.g. cable) in the event of fire in accordance with DIN 4102 Part 12 and is verified by test certificates.
13What is the difference between the two standards HD 629 and IEC 60502?
The differences between CENELEC HD 629.1 S3:2019 and IEC 60502-4:2010 relate to type testing and are shown in the following table.
Comparison HD629-1 with IEC60502-4Download
14What are diisocyanates and what needs to be considered when handling them?
BBC Cellpack's casting resins consist of two components, a resin component and a hardener component. The hardener of PUR casting resins contains so-called isocyanates (isocyanates are the main starting materials for the production of polyurethanes). Because they pose health risks that can be minimized if used correctly, the EU has made training mandatory. This training requirement for handling polyurethanes applies to all PUR casting resins (EG, GG, AMX) from BBC Cellpack. The instructions in the respective safety data sheets must be observed.
15What is meant by "resistant to chemical influences"?
Resistant to chemical influences" refers to general chemical compatibility. Tests are carried out with acids (e.g. 10 % hydrochloric acid), alkalis (e.g. 10 % NaOH), polar (e.g. isopropanol/water) and apolar solvents (e.g. transformer oil).
16What is meant by "alkaline earths"?
The term alkaline earths is a generalization of the term alkaline earth metals, such as magnesium or calcium. Together with water, alkaline earth metals form chemical solutions. The resistance to such chemical solutions is indicated in the product properties.
17Does BBC Cellpack have special products for cable joints?
Cable joints are highly flexible special cables for industrial applications with high mechanical loads. BBC Cellpack does not offer any special fittings for this purpose.
18Which cleaning agents are approved for cleaning BBC Cellpack cable accessories?
Cleaning agents may contain ingredients that permanently impair the properties of the components. It is therefore recommended to use only the enclosed cleaning cloths RT or the Universal Cleaner 121 from BBC Cellpack. For other cleaning agents (e.g. isopropanol, cold cleaners), a maximum concentration of 10 % aliphatic hydrocarbons (C6-C8) in the cleaning agent formulation must be observed.
19What warnings and safety instructions apply to BBC Cellpack cable accessories?
The warning and safety instructions are enclosed with every BBC Cellpack cable set, see document.
Warnings and safety instructionsDownload
20Which lubricant can be used when using peeling tools (e.g. P20 or FLM20)?
For easier handling of the peeling tools, a lubricant can be applied to the desired area (cable sheath, insulation, conductive layer). The silicone grease from BBC Cellpack (article 124055) is recommended for this purpose. Lubricant residues should be removed with a cleaning cloth or a suitable cleaning agent, e.g. Universal Cleaner 121. The use of product-specific lubricants such as GM1, GM2 or GM3 is not recommended because the quantities are adapted to the assembly of the respective product.
21How do you select BBC Cellpack cable accessories (joints, terminations)?
The cable used (system voltage, number of cores, conductor material, shape and cross-section, shielding, ...) and the application (connection, branch, termination, environmental conditions, ...) are decisive for the selection of a cable assembly. The large number of selection criteria and the complexity of the possible combinations require experience in the selection process. This is why BBC Cellpack offers experienced sales consultants and special training courses.
22What is the difference between low and medium voltage fittings?
In low-voltage applications, the conductor insulation and the sheath must be simulated using a joint or an end closure. Casting resins, silicone gels or shrink sleeves can be used for this purpose. In medium voltage, conductor insulation is much more complex because the electric field must be taken into account. Field control elements must also be used for this.
23What does the CE marking mean?
The CE marking confirms that a product complies with the applicable safety, health and environmental protection requirements in the European Economic Area (EEA). It is not a voluntary test, but is mandatory for products if the product requirements are defined in a corresponding EU directive. For BBC Cellpack low-voltage accessories, this is the Low Voltage Directive (2014/35/EU). After a conformity assessment, the CE mark is printed on the product label and the CE declaration of conformity is stored in the download area of the web catalog. No EU directive is applicable to medium-voltage accessories, which means that no CE conformity can be issued.
24Do BBC Cellpack cable accessories have integrated strain relief?
The standards for fittings do not include a tensile test of assembled joints. The standard for compression and screw connectors refers to DIN EN 61238-1, which describes the requirements for mechanical testing. BBC Cellpack offers shells with integrated strain relief for some gel and cast resin fittings (Easycell, P-sleeves).
25Are self-welding tapes UV-resistant when installed above ground?
BBC Cellpack offers self-sealing tapes with UV stabilization, i.e. tapes No. 60 and 62, which means that the properties of the tapes are not or not significantly changed by UV radiation.
26What is the difference between IP68 and EN 50393?
Both IP68 and EN 50393 deal with the protection and performance of electrical components and serve different purposes and industries. IP68 is part of a universal rating system for the degree of protection applicable to various devices and enclosures, ensuring their resistance to dust and water. EN 50393, on the other hand, is a specific standard for low-voltage cable connections and terminations, which ensures their reliability and safety through comprehensive testing under various conditions.

9Can a BBC Cellpack EASYCELL sleeve also be installed at cold temperatures?
BBC Cellpack EASYCELL couplings can be installed in temperatures ranging from -10 °C to +60 °C. As with all other couplings, care must be taken to ensure that there is no moisture present anywhere on the coupling; this includes snow and ice.
10Can the BBC Cellapack EASYCELL sleeves also be used as end sleeves?
In principle, this application is possible, but care must be taken to ensure sufficient gel displacement. This means that both gel surfaces must close around the cable end to ensure a seal against moisture.
11Can BBC Cellpack EASYCELL sleeves be used in water?
All BBC Cellpack EASYCELL joints have been tested in accordance with the EN 50393 test standard. This also requires the load cycle test with 0.1 bar water pressure. This means that the sleeve can be used in water depths of up to 1 meter. The instructions for installation must be observed.
12Can the BBC Cellpack EASYCELL connecting sleeves be combined with CU conductors and AL conductors?
Yes, the BBC Cellpack EASYCELL 3V, 4V and 5V can be combined with CU conductors and AL conductors, as they have a tinned connector block with a separator.
13Are gel sleeves suitable for repeated use (reusability)?
The gel joints from the EASYCELL, EASY-PROTECT and EASY-PROTECT Inline product family are designed for single use only.
14What is the advantage of BBC Cellpack gels?
The gel technology combines easy handling, label-free material and unlimited shelf life. The electrical properties ensure a permanent and reliable cable connection after installation.
15Do minimum distances have to be maintained for low-voltage cast resin fittings?
In order to establish a safe electrical connection, a minimum distance of 5 mm is specified between the terminals/connectors/conductors and the molded shell or the housing of the junction box for low voltage (up to 1kV). For non-insulated connectors, the 5 mm also applies between the individual connectors.
16Do cast resin sleeves protect against the penetration of gases?
The DIN EN 50393 test standard does not include testing of the overall system for the influence of gases. Changes in the cast resin properties as a function of gases and their concentration were not tested for BBC Cellpack sleeves.
17Do cast resin sleeves protect against water ingress?
The cast resin systems protect against water penetration up to a depth of 1 m, provided that they are installed correctly and in accordance with the installation instructions. The DIN EN 50393 test standard includes corresponding tests with a water depth of 1 m.
18Is it possible to use Cellpack cast resins in conjunction with other housing shapes (e.g. junction box)?
In principle, this is not a problem as long as the casting resin cannot escape during casting until it has hardened.
19Can a polyurethane 2-component casting resin still be used after the best-before date has expired?
Use within the best-before date and the permissible storage temperature guarantees the specified properties and thus also safe handling and function in the approved application. If the best-before date is exceeded, the specified properties can no longer be guaranteed.
20Can three cable ends be connected together?
BBC Cellpack branch joints are designed for a main conductor that is not cut. For this reason, an additional connecting sleeve is required for 3 cable ends, see illustration. Branch joints with WAGO clamps are an exception to this rule. They can be used to connect three cable ends with up to 5 x 0.5mm² - 5 x 4mm², see illustration.
Image of connecting 3 cablesDownload
21Can joints that have not been completely grouted be filled with grouting compound afterwards?
Subsequent filling with potting compound is not possible, as perfect potting cannot be guaranteed.
22Are BBC Cellpack clothings resistant to organic fertilizers?
Organic fertilizers consist of different chemical substances such as ammonia or nitrate in different concentrations. It is therefore not possible to carry out a meaningful test of the fittings with regard to organic fertilizers.
23Are BBC Cellpack potting compounds resistant to gasoline?
BBC Cellpack's polyurethane-based potting compounds are susceptible to petrol, which can lead to a change in their properties.
24What is the difference between curing time and pot life?
The curing time describes the time required to achieve 100 % curing of component A and B with the full mechanical properties. The pot life is a standardized term which is also colloquially defined as the processing time. Depending on the different temperatures, fast or slow reactions are possible.
25What is the advantage of BBC Cellpack cast resin sets?
The cast resin fittings from BBC Cellpack have been tried and tested for decades. The electrical and mechanical properties after curing ensure a durable and reliable cable connection. Different cast resin variants are available depending on the application.
26What must be considered in connection with casting resins with rain or moisture?
Polyurethane (PUR) casting resins consist of two components, a resin component and a hardener component. Rain or moisture during processing will cause the mixture to foam. The specified electrical and mechanical properties are then not fulfilled. For this reason, working with PUR casting resins in damp conditions should generally be avoided. After curing, PUR casting resins are insensitive to moisture.
27What curing time does the EG casting resin require depending on the ambient temperature?
The curing time of the EG casting resin depends on the ambient temperature and the amount of casting resin, see diagram. The specified processing temperature of the casting resin must be observed.
Diagram of curing time for EG casting resinDownload
28Which casting resins does BBC Cellpack offer?
The casting resins are characterized by excellent electrical insulating properties. However, different casting resins can be selected depending on the area of application:
EG - universal casting resin for plastic cables, paper-insulated low-voltage cables and telecommunication, control and signal cables. For medium-voltage cables, EG serves as protection against mechanical influences and moisture.
GG - special casting resin for occupational safety due to reduced hazardous substance labeling. It is suitable for plastic and paper-insulated low-voltage cables.
CG - Environmentally friendly, removable, hydrocarbon-based cold casting compound. It is free of silicones, isocyanate and has no hazardous substance labeling.

CG - Environmentally friendly, removable, hydrocarbon-based cold casting compound. It is free of silicones, isocyanate and has no hazardous substance labeling.
29What temperatures should be maintained during transportation and storage of BBC Cellpack PUR cast resin products?
The recommended transport and storage temperature for the PUR casting resin products offered by BBC Cellpack is between 15 °C and 35 °C.
30How do I dispose of excess casting resin?
Any unused casting resin will cure inside the bag; once it has fully cured, it can simply be disposed of with regular trash. This requires that components A and B be thoroughly mixed.
31How long does a cast resin bag have to be kneaded?
During kneading, the resin and hardener mix and start an exothermic chemical reaction. The enclosed assembly instructions refer to a mixing time of the bag of 3 minutes. If the mixing time is shorter, the components will not be sufficiently mixed, the reaction will not take place and the mixture will not harden. The specified electrical and mechanical properties will not be met in these cases. A slightly longer mixing time (plus 1 minute), on the other hand, is not critical.
32Can a cast resin socket be cast under tension?
The joint can be put into operation immediately after casting, i.e. it can also be cast under voltage. The relevant "Live working regulations" must be observed.
33Which sleeve systems does BBC Cellpack offer for low voltage?
BBC Cellpack offers three technologies for low voltage: shrink sleeves, cast resin sleeves and gel sleeves. With shrink joints, the conductor insulation and mechanical stability are achieved with heat-shrinkable sleeves. Only connections and no branches are possible. Cast resin joints use a polyurethane 2-component cast resin, which is poured into a mold. After hardening, the cast resin provides electrical insulation and mechanical protection. The joints are available as a connection and also as a branch in different geometries (Y, T, H). Gel joints insulate the connector with the aid of gel displacement. Mechanical protection is provided by the shell. These sleeves are also available as joints and branches.
34How can pump lines be connected?
Pump cables differ from radial cables due to their flat design. Usually, fine-stranded conductors (class 5) with a maximum of 4 cores are used. A type M cast resin joint from BBC Cellpack is recommended for this application. When selecting the size of the joint, ensure that there is sufficient space for the flat cable to be inserted (max. cable Ø mm). Crimp connectors are recommended for the fine-stranded conductors and the HKB adhesive kit tape (article 127651) is recommended for easy sealing of the flat cable to the sleeve shell.
35For which conductor types/conductor classes can BBC Cellpack screw connectors type CSV, CSV-T and screw cable lug type CSK be used?
The following conductor types are tested at the factory: RE (round, solid), RM (round, stranded), SE (sector, solid) and SM (sector, stranded). Connectors and cable lugs are approved for conductor class 1 (solid conductor construction) and 2 (stranded conductor construction). Compacted conductors (RMv and SMv) are also supported. No approval is available for conductor class 5 (fine stranded conductors) and conductor class 6 (superfine stranded conductors).
36Is it possible to use clamps with spring clamp technology in conjunction with Cellpack potting compounds (gel / cast resin)?
WAGO's spring clamping technology has been tested and approved for applications using PUR gel and for Cellpack cast resin types EG and CG. Application testing for other cast resin types is available on request.
37Can BBC Cellpack DR and DR-L crimp connectors be used for solid conductors?
A second crimping point is recommended for solid conductors. This is only possible with the long DR-L connectors, but not with the short DR connectors. For this reason, only the long DR-L connectors are approved for use with solid conductors.
38Can BBC Cellpack DR crimp connectors connect different conductor classes or wire cross-sections?
BBC Cellpack DR crimp connectors are designed for conductor classes 5 and 6. Different conductor cross-sections are possible within the specified application range.
39Which crimping pliers can be used for AVS wire connectors?
All crimping pliers can be used.
40Which connectors can be used for connecting concentric conductors (Ceander, wire screen)?
Concentric conductors are arranged concentrically around the current-carrying cores in LV cables and act as a combined protective earth conductor (PE), neutral conductor (N) or shield. They can be designed as a Ceander or wire screen and do not have a fixed conductor shape. For concentric conductors, compression connectors tested in accordance with DIN 46267 can be used.
41How are compression cable lugs fitted?
Pressing takes place from the center hole (according to the markings) in the direction of the cable. Pressing makes the cable lug slightly longer. For this reason, a crimping allowance of 5mm (Cu) or 10mm (Al) is taken into account when preparing the cable. A suitable crimping tool in accordance with DIN is required for a DIN cable lug. The crimping insert is selected according to the outer diameter. In the case of a manufacturer-specific cable lug, the cross-sectional specification is usually used as the crimping insert.
42How are press connectors installed?
Pressing takes place from the center of the connector (according to the markings) in the direction of the cable. Pressing makes the compression connector slightly longer. For this reason, a pressing allowance of 5mm (Cu) or 10mm (Al) is taken into account when preparing the cable. A suitable crimping tool in accordance with DIN is required for a DIN connector. The crimping insert is selected according to the outer diameter. In the case of a manufacturer-specific connector, the cross-sectional specification is usually used as the crimping die.
43How is a BBC Cellpack screw connector with shear head screws (CSV, CSV-T, CSV-LHS) assembled?
For screw connectors with tear-off head screws, all screws must be tightened lightly one after the other during assembly. Then, for connectors with 2 screws per cable side, the screw to the cable is torn off first, followed by the screw to the center of the connector. For connectors with only one screw per cable side, tighten the screw evenly until it breaks off.
44Can a SRMAHV type shrink sleeve also be used to repair a cable sheath of E90 cables?
Whether a shrink sleeve is possible for cable sheath repair is up to the cable manufacturer to assess the damage. It provides mechanical protection and prevents the ingress of moisture. The properties for the operation of E90 cables are independent of the cable sheath, so that a shrink sleeve can be used.
45Is it possible to use SMH fittings under plaster?
The heat-shrinkable fittings offered by BBC Cellpack are suitable for installation under plaster. The use of individual conduits without hot-melt adhesive is not recommended, as in this case there is no protection against the ingress of moisture and the insulating function of the conduit over the remote cable cannot be fulfilled.
46Can a hot air gun also be used to shrink heat-shrink components?
A hot air gun can be used for shrinking. However, the heat input is lower compared to a gas burner. This extends the duration of the shrinking process.
47Is it possible to assemble your own sleeve from different shrink tubes?
BBC Cellpack's sleeves undergo extensive testing procedures, such as the EN 50393 test standard, which guarantees that the sleeves function permanently and are safe. We strongly advise against making your own sleeve constructions from several shrink sleeves.
48Can the SRMAHV shrink sleeves also be used to repair a cable sheath for low and medium voltage cables?
The operating voltage of the cable is not the decisive factor when selecting the correct sleeve. The function of sleeves is to restore the cable outer sheath in its two functions: Protection against moisture and mechanical protection. A cable may generally only be repaired with a sleeve if the damage only affects the cable outer sheath. If additional damage to the core insulation is detected, repair using a sleeve is not permitted.
49Do BBC Cellpack tubes - type SR(H), SRAT and SRBB - contain chlorine and sulphur?
BBC Cellpack SR(H), SRAT, SRBB tubing contains no chlorine, no other halogenated materials, no sulphur, no heavy metals and no other substances hazardous to health. A corresponding RoHS and REACH declaration of conformity is available.
50What is the advantage of BBC Cellpack heat-shrinkable card clothing?
BBC Cellpack's heat shrink fittings (sleeves and terminations) have been tried and tested for decades. The electrical and mechanical properties after cooling ensure a durable and reliable cable connection. Heat shrink products can also be ordered for stock, as they can be stored indefinitely.
51What needs to be considered when using components containing halogens?
Halogen-containing components (e.g. flame-retardant conduits) can be used on halogen-free cables (PE, XLPE). This also applies vice versa, halogen-free components can also be used on halogen-containing cables (PVC).
52Which heat-shrink tubing is approved by UL (Underwriters Laboratories)?
UL approved are the hoses type SR1F and SR1F3. Both hose types are listed in the UL directory under document number E172094
53How does a shrink sleeve work?
A hose is first extruded from polyolefin granulate. Depending on the hose type, the hot-melt adhesive is also applied in this step (co-extruded). The hoses are then subjected to electron beam cross-linking. This changes the molecular structure, giving the tubes a "memory". In a further work step with the addition of heat, the tubing is expanded to the required diameter, then cooled directly and finally cut. When heated, the tube "remembers" its original state and shrinks back.
54What IP protection rating do shrink sleeves and shrink tubing have?
The classification of IP degrees of protection is a component of DIN EN 60529 (VDE 0470). For the test procedure, protection against the ingress of solids or liquids is provided by an enclosure. There is no additional housing for shrink sleeves and shrink hoses and therefore no IP degree of protection can be specified.
55How is a SEH breakout boot shrunk?
The breakout boot must be positioned correctly and the gas burner set to a soft yellow flame. Starting from the center, shrink first in the direction of the cable sheath. Even radial heating is important. Then shrink from the center towards the fingers. The inside of the splice must also be heated. After a short time, the adhesive slowly emerges at the ends. Important indicators of correct shrinkage are even wall thicknesses and straight marking.
Image how to shrink breakout bootsDownload
56How is heat shrink tubing (SR...) shrunk?
The shrink sleeve must be positioned correctly and the gas burner set to a soft yellow flame. Starting from the center, one side is shrunk completely first. It is important to ensure even radial heating. The other side is then shrunk from the center. In the case of a hose with hot-melt adhesive (SRH), the adhesive slowly emerges at the ends. Important indicators of correct shrinkage are even wall thicknesses and straight labeling.
Image how to shrink tubesDownload
57What are the transportation and storage conditions for BBC Cellpack shrink sleeves and components for low-voltage cables?

Cast Resin Technology
1Are shrink, cast resin or gel sleeves from BBC Cellpack suitable for use in potentially explosive atmospheres?
There is currently no approval for use in potentially explosive atmospheres.
2What are diisocyanates and what needs to be considered when handling them?
BBC Cellpack's casting resins consist of two components, a resin component and a hardener component. The hardener of PUR casting resins contains so-called isocyanates (isocyanates are the main starting materials for the production of polyurethanes). Because they pose health risks that can be minimized if used correctly, the EU has made training mandatory. This training requirement for handling polyurethanes applies to all PUR casting resins (EG, GG, AMX) from BBC Cellpack. The instructions in the respective safety data sheets must be observed.
3Do minimum distances have to be maintained for low-voltage cast resin fittings?
In order to establish a safe electrical connection, a minimum distance of 5 mm is specified between the terminals/connectors/conductors and the molded shell or the housing of the junction box for low voltage (up to 1kV). For non-insulated connectors, the 5 mm also applies between the individual connectors.
4Do cast resin sleeves protect against the penetration of gases?
The DIN EN 50393 test standard does not include testing of the overall system for the influence of gases. Changes in the cast resin properties as a function of gases and their concentration were not tested for BBC Cellpack sleeves.
5Do cast resin sleeves protect against water ingress?
The cast resin systems protect against water penetration up to a depth of 1 m, provided that they are installed correctly and in accordance with the installation instructions. The DIN EN 50393 test standard includes corresponding tests with a water depth of 1 m.
6Is the 2-component PUR casting resin EG radon-proof?
The 2-component PUR casting resin EG has not been tested for its impermeability to radon. It is therefore not possible to make a binding statement on radon impermeability.
7Is it possible to use Cellpack cast resins in conjunction with other housing shapes (e.g. junction box)?
In principle, this is not a problem as long as the casting resin cannot escape during casting until it has hardened.
8Can a polyurethane 2-component casting resin still be used after the best-before date has expired?
Use within the best-before date and the permissible storage temperature guarantees the specified properties and thus also safe handling and function in the approved application. If the best-before date is exceeded, the specified properties can no longer be guaranteed.
9Can three cable ends be connected together?
BBC Cellpack branch joints are designed for a main conductor that is not cut. For this reason, an additional connecting sleeve is required for 3 cable ends, see illustration. Branch joints with WAGO clamps are an exception to this rule. They can be used to connect three cable ends with up to 5 x 0.5mm² - 5 x 4mm², see illustration.

10Can joints that have not been completely grouted be filled with grouting compound afterwards?
Subsequent filling with potting compound is not possible, as perfect potting cannot be guaranteed.
11Are BBC Cellpack clothings resistant to organic fertilizers?
Organic fertilizers consist of different chemical substances such as ammonia or nitrate in different concentrations. It is therefore not possible to carry out a meaningful test of the fittings with regard to organic fertilizers.
12Are BBC Cellpack potting compounds resistant to gasoline?
BBC Cellpack's polyurethane-based potting compounds are susceptible to petrol, which can lead to a change in their properties.
13What is the difference between curing time and pot life?
The curing time describes the time required to achieve 100 % curing of component A and B with the full mechanical properties. The pot life is a standardized term which is also colloquially defined as the processing time. Depending on the different temperatures, fast or slow reactions are possible.
14What is the advantage of BBC Cellpack cast resin sets?
The cast resin fittings from BBC Cellpack have been tried and tested for decades. The electrical and mechanical properties after curing ensure a durable and reliable cable connection. Different cast resin variants are available depending on the application.
15What must be considered in connection with casting resins with rain or moisture?
Polyurethane (PUR) casting resins consist of two components, a resin component and a hardener component. Rain or moisture during processing will cause the mixture to foam. The specified electrical and mechanical properties are then not fulfilled. For this reason, working with PUR casting resins in damp conditions should generally be avoided. After curing, PUR casting resins are insensitive to moisture.
16What curing time does the EG casting resin require depending on the ambient temperature?
The curing time of the EG casting resin depends on the ambient temperature and the amount of casting resin, see diagram. The specified processing temperature of the casting resin must be observed.
Diagram of curing time for EG casting resinDownload
17Which casting resins does BBC Cellpack offer?
The casting resins are characterized by excellent electrical insulating properties. However, different casting resins can be selected depending on the area of application:
EG - universal casting resin for plastic cables, paper-insulated low-voltage cables and telecommunication, control and signal cables. For medium-voltage cables, EG serves as protection against mechanical influences and moisture.
GG - special casting resin for occupational safety due to reduced hazardous substance labeling. It is suitable for plastic and paper-insulated low-voltage cables.
CG - Environmentally friendly, removable, hydrocarbon-based cold casting compound. It is free of silicones, isocyanate and has no hazardous substance labeling.

GG - special casting resin for occupational safety due to reduced hazardous substance labeling. It is suitable for plastic and paper-insulated low-voltage cables.
CG - Environmentally friendly, removable, hydrocarbon-based cold casting compound. It is free of silicones, isocyanate and has no hazardous substance labeling.
18What temperatures should be maintained during transportation and storage of BBC Cellpack PUR cast resin products?
The recommended transport and storage temperature for the PUR casting resin products offered by BBC Cellpack is between 15 °C and 35 °C.
19How do I dispose of excess casting resin?
Any unused casting resin will cure inside the bag; once it has fully cured, it can simply be disposed of with regular trash. This requires that components A and B be thoroughly mixed.
20How long does a cast resin bag have to be kneaded?
During kneading, the resin and hardener mix and start an exothermic chemical reaction. The enclosed assembly instructions refer to a mixing time of the bag of 3 minutes. If the mixing time is shorter, the components will not be sufficiently mixed, the reaction will not take place and the mixture will not harden. The specified electrical and mechanical properties will not be met in these cases. A slightly longer mixing time (plus 1 minute), on the other hand, is not critical.
21Can a cast resin socket be cast under tension?
The joint can be put into operation immediately after casting, i.e. it can also be cast under voltage. The relevant "Live working regulations" must be observed.
22How can pump lines be connected?
Pump cables differ from radial cables due to their flat design. Usually, fine-stranded conductors (class 5) with a maximum of 4 cores are used. A type M cast resin joint from BBC Cellpack is recommended for this application. When selecting the size of the joint, ensure that there is sufficient space for the flat cable to be inserted (max. cable Ø mm). Crimp connectors are recommended for the fine-stranded conductors and the HKB adhesive kit tape (article 127651) is recommended for easy sealing of the flat cable to the sleeve shell.
23Is it possible to use clamps with spring clamp technology in conjunction with Cellpack potting compounds (gel / cast resin)?
WAGO's spring clamping technology has been tested and approved for applications using PUR gel and for Cellpack cast resin types EG and CG. Application testing for other cast resin types is available on request.
Heat Shrink Technology
1Are shrink, cast resin or gel sleeves from BBC Cellpack suitable for use in potentially explosive atmospheres?
There is currently no approval for use in potentially explosive atmospheres.
2Can a SRMAHV type shrink sleeve also be used to repair a cable sheath of E90 cables?
Whether a shrink sleeve is possible for cable sheath repair is up to the cable manufacturer to assess the damage. It provides mechanical protection and prevents the ingress of moisture. The properties for the operation of E90 cables are independent of the cable sheath, so that a shrink sleeve can be used.
3Is the SRAT or SRBB heat-shrink tubing suitable for protecting busbars and shortening distances?
SRAT heat-shrinkable tubing can be used as wire insulation tubing for terminations and as protection against corrosion. It must not be used to protect busbars or to shorten the distances between these busbars. This function has not been tested and can therefore not be guaranteed. The suitable solution for this application is the SRBB conduit.
4Is it possible to use SMH fittings under plaster?
The heat-shrinkable fittings offered by BBC Cellpack are suitable for installation under plaster. The use of individual conduits without hot-melt adhesive is not recommended, as in this case there is no protection against the ingress of moisture and the insulating function of the conduit over the remote cable cannot be fulfilled.
5Can a hot air gun also be used to shrink heat-shrink components?
A hot air gun can be used for shrinking. However, the heat input is lower compared to a gas burner. This extends the duration of the shrinking process.
6Can the SRMAHV sleeve be used for external cable protection applications for medium-voltage cables?
Yes, the SRMAHV sleeves are already being used successfully as external protection for some medium-voltage products up to Umax = 12 kV. They can therefore be used to protect cables up to a voltage of Umax = 12 kV.
7Is it possible to assemble your own sleeve from different shrink tubes?
BBC Cellpack's sleeves undergo extensive testing procedures, such as the EN 50393 test standard, which guarantees that the sleeves function permanently and are safe. We strongly advise against making your own sleeve constructions from several shrink sleeves.
8Can the SRMAHV shrink sleeves also be used to repair a cable sheath for low and medium voltage cables?
The operating voltage of the cable is not the decisive factor when selecting the correct sleeve. The function of sleeves is to restore the cable outer sheath in its two functions: Protection against moisture and mechanical protection. A cable may generally only be repaired with a sleeve if the damage only affects the cable outer sheath. If additional damage to the core insulation is detected, repair using a sleeve is not permitted.
9Can the CHM / CHMSV 24 kV connecting sleeves also be used for 12 kV cables?
Yes, in principle the joints can also be used for lower system voltages. However, it must be ensured that the cable cross-section and the minimum diameter over insulation are within the specified range of the fitting. The reverse conclusion, i.e. use for higher system voltages, is not permitted.
10Do BBC Cellpack tubes - type SR(H), SRAT and SRBB - contain chlorine and sulphur?
BBC Cellpack SR(H), SRAT, SRBB tubing contains no chlorine, no other halogenated materials, no sulphur, no heavy metals and no other substances hazardous to health. A corresponding RoHS and REACH declaration of conformity is available.
11What is the advantage of BBC Cellpack heat-shrinkable card clothing?
BBC Cellpack's heat shrink fittings (sleeves and terminations) have been tried and tested for decades. The electrical and mechanical properties after cooling ensure a durable and reliable cable connection. Heat shrink products can also be ordered for stock, as they can be stored indefinitely.
12What needs to be considered when using components containing halogens?
Halogen-containing components (e.g. flame-retardant conduits) can be used on halogen-free cables (PE, XLPE). This also applies vice versa, halogen-free components can also be used on halogen-containing cables (PVC).
13Which heat-shrink tubing is approved by UL (Underwriters Laboratories)?
UL approved are the hoses type SR1F and SR1F3. Both hose types are listed in the UL directory under document number E172094
14How does a shrink sleeve work?
A hose is first extruded from polyolefin granulate. Depending on the hose type, the hot-melt adhesive is also applied in this step (co-extruded). The hoses are then subjected to electron beam cross-linking. This changes the molecular structure, giving the tubes a "memory". In a further work step with the addition of heat, the tubing is expanded to the required diameter, then cooled directly and finally cut. When heated, the tube "remembers" its original state and shrinks back.
15What IP protection rating do shrink sleeves and shrink tubing have?
The classification of IP degrees of protection is a component of DIN EN 60529 (VDE 0470). For the test procedure, protection against the ingress of solids or liquids is provided by an enclosure. There is no additional housing for shrink sleeves and shrink hoses and therefore no IP degree of protection can be specified.
16How is a SEH breakout boot shrunk?
The breakout boot must be positioned correctly and the gas burner set to a soft yellow flame. Starting from the center, shrink first in the direction of the cable sheath. Even radial heating is important. Then shrink from the center towards the fingers. The inside of the splice must also be heated. After a short time, the adhesive slowly emerges at the ends. Important indicators of correct shrinkage are even wall thicknesses and straight marking.
Image how to shrink breakout bootsDownload
17How is heat shrink tubing (SR...) shrunk?
The shrink sleeve must be positioned correctly and the gas burner set to a soft yellow flame. Starting from the center, one side is shrunk completely first. It is important to ensure even radial heating. The other side is then shrunk from the center. In the case of a hose with hot-melt adhesive (SRH), the adhesive slowly emerges at the ends. Important indicators of correct shrinkage are even wall thicknesses and straight labeling.
Image how to shrink tubesDownload
18What are the transportation and storage conditions for BBC Cellpack shrink sleeves and components for low-voltage cables?
The conditions for transport and storage are the same. A temperature range of 0 °C to 40 °C must be maintained. Deviations from these conditions may impair the function of individual components (e.g., filling material) or make assembly difficult or impossible.
19What are the installation conditions for BBC Cellpack shrink sleeves and components for low-voltage cables?
The installation requirements are described in the product's installation instructions. The temperature range for installation is 0 °C to 40 °C.
20What are the operating conditions for BBC Cellpack shrink sleeves and components for low-voltage cables?
The operating temperature range for heat shrink components (e.g. end caps, split caps) is -40 °C ...+100 °C. For thick-walled heat-shrink tubing and shrink sleeves for LV cables, higher temperatures of up to 120 °C are also permissible. The applicable operating conditions can be found in the product data sheet. The operating conditions of the cable used must also be observed.
Medium Voltage
1Are BBC Cellpack insulating tapes (e.g. No. 128) suitable for repairing cables and wires?
As long as only the cable sheath (outer plastic) is damaged, the insulating tape is suitable as temporary protection. Sealing against moisture is not guaranteed. However, if the basic insulation is also damaged, simple insulating tape is no longer sufficient. The use of a gel, cast resin or shrink sleeve is then recommended. The same applies to damage to the conductor.
2Are shrink, cast resin or gel sleeves from BBC Cellpack suitable for use in potentially explosive atmospheres?
There is currently no approval for use in potentially explosive atmospheres.
3Why is personal protective equipment necessary when preparing earth cables?
When preparing a ground cable, carcinogenic gases and vapors are produced when the bitumen layer is flamed and toxic lead dust is produced when the oxide layer of the lead sheath is broken open. For this reason, PPE (personal protective equipment) must be worn when preparing the ground cable, for example article 447993 "PPE/(G+H+3Pb)". When using PPE, a risk assessment should be carried out beforehand.
4Which lubricant can be used when using peeling tools (e.g. P20 or FLM20)?
For easier handling of the peeling tools, a lubricant can be applied to the desired area (cable sheath, insulation, conductive layer). The silicone grease from BBC Cellpack (article 124055) is recommended for this purpose. Lubricant residues should be removed with a cleaning cloth or a suitable cleaning agent, e.g. Universal Cleaner 121. The use of product-specific lubricants such as GM1, GM2 or GM3 is not recommended because the quantities are adapted to the assembly of the respective product.
5Is it possible to use BBC Cellpack medium voltage cable accessories for a cable with (H)EPR insulation?
BBC Cellpack cable accessories can be used for cables with (H)EPR insulation, but the highest permissible temperature at the conductor during undisturbed operation must not exceed 90 °C (according to HD 620, IEC 60502-2).
6Is it possible to use the CHE/CAE end caps with the class 5 & 6 conductor?
Yes, CHE/CAE terminations can be used with conductor classes 5 & 6 in accordance with the cross-sectional areas in the data sheet. Appropriate cable lugs suitable for this conductor class must be used.
7Is it possible to use the CHESK/CAESK end caps with the class 5 & 6 conductor?
CHESK/CAESK terminations are supplied with a screw-type cable lug, which cannot be used on conductor classes 5 & 6
8Is it possible to use the CHM sleeves with the class 5 & 6 conductor?
Yes, joints can be used with conductor class 5 & 6 in accordance with the cross-section ranges in the data sheet. Appropriate compression connectors suitable for this conductor class must be used.
9Is it possible to use the CHMSV sleeves with the class 5 & 6 conductor?

10Are end sleeves and branch joints for medium voltage available from BBC Cellpack?
End sleeves and branch joints for medium voltage are not included in the BBC Cellpack range.
11What is meant by the term "rated voltage" Uo/U (Um)?
The rated voltage of a cable is the voltage for which the cable is designed. In accordance with DIN VDE 0298-3, the rated voltage is expressed in volts by the ratio of two values Uo/U. Uo is the effective value of the voltage between a conductor and earth (conductor-earth voltage). U is the effective value of the voltage between two conductors (conductor-conductor voltage). In addition, the highest permissible voltage Um (maximum voltage) is given in brackets in the IEC regulations Uo/U (Um). BBC Cellpack products are specified in the designation with the maximum permissible voltage Um.
12What are the transportation and storage conditions for BBC Cellpack medium-voltage hybrid shrink products?
The conditions for transport and storage are the same. A temperature range of 0 °C to 50 °C and a relative humidity of 0–50% must be maintained. For short periods (up to a maximum of 120 minutes), a temperature range of -40 °C to +60 °C with a relative humidity of 0–70% is also permissible. Deviations from these conditions may lead to limitations in the function of individual components (e.g., filling material, field control elements) or make installation difficult or impossible.
13What are the assembly conditions for BBC Cellpack medium-voltage hybrid shrink products?
The installation requirements are described in the product's installation instructions. The temperature range for installation is 0 °C to 40 °C.
14What are the operating conditions for BBC Cellpack medium-voltage hybrid shrink products?
The operating conditions depend on the cable used. For many polymer-insulated cables (e.g. XLPE), the maximum conductor temperature in normal operation is 90 °C. For paper-insulated cables, it is usually only 60 °C. For paper-insulated cables, it is usually only 60 °C. The applicable operating conditions can be found in the data sheet for the cable used.
15Can the lubricant from other manufacturers be used instead of GM1 for cable connections?
No, you can't. Lubricants and lubricants are assigned to specific cable accessories. Most of them have electrical properties in specific areas (e.g. dissipation factor or dielectric constant). Standardization is not possible.
16Can the Cellpack test adapters also be used for screwable T-cable connections from other manufacturers?
The test adapters are intended exclusively for use in screwable shielded T-shaped EPDM cable connectors of types CTS and CTKS. Use of the screw inserts in cable connectors from other manufacturers is not permitted.
17Does the glitter effect (crystal formation) on the screw-on and plug-in EPDM cable connectors affect quality, function or service life?
The glitter effect (crystal formation) has no negative influence on the function, quality or service life of the EPDM cable connections. Depending on the storage period and temperature, it can occur on all surfaces. If it is very pronounced, it is recommended to wipe out the inner surfaces before installation as part of the inspection and cleaning process.
18Can the contact bolt be reused with Cellplux CTS and CTKS plug connectors?
The contact bolt can be removed with a long socket and can be reused. The use of an additional set is recommended, as the surface must be cleaned and a new GM1 lubricant must be used. Appropriate ventilation must be ensured during assembly. The required torque is specified in the respective installation instructions.
19Can the BBC Cellpack plugs with wound sealing be used in the open air (with UV radiation)?
The wrapped seal is not UV-resistant and must therefore be additionally wrapped with UV-stabilized PVC insulating tape (e.g.: No. 328).
20With which degree of contamination, according to IEC TS 60815-1, can the BBC Cellpack connectors (CTS, CWS, CTKS, CGS, CTS-S) be used?
The degree of contamination is not important for BBC Cellpack's shielded plug connections in contrast to unshielded plug connections. The CTS, CWS, CTKS, CGS, CTS-S connectors may therefore be used in environments with varying degrees of contamination.
21What is the difference between EPDM and SIR insulation for cable connectors?
Ethylene propylene diene rubber (EPDM) and silicone rubber (SIR) are both good insulation materials and therefore equivalent. Connectors from BBC Cellpack have been successfully tested with both insulation materials in accordance with HD 629.1.
22What is meant by contact protection for shielded cable plugs?
Shielded plug-in or screw-type cable connectors with and without metal housings are safe to touch, earthed equipment when properly earthed and installed in undisturbed operation. As it is not always apparent from the outside whether undisturbed operation is present, contact with live cable connectors is generally not recommended.
23How high can the measurable voltage be at the capacitive measuring point of a CTS plug?
The calculated possible voltage at the capacitive measuring point is between 0.08 ... 0.5 Uo and depends on the capacitance ratio (conductor to measuring point and measuring point to earth). This means that even with a "small" medium voltage of 6/10(12) kV, up to 0.5 Uo = 3 kV can be achieved at the measuring point. An open measuring point is therefore always life-threatening! The measurement is the responsibility of the system operator and may only be carried out by qualified persons.
24How do you select a CTKSA surge arrester?
Special calculations are required for the selection of a CTKSA surge arrester, taking into account data on the relevant influencing factors in the network. Details are described in the enclosed brochure.

27Can type CSV screw connectors and type CSK screw cable lugs be used for Al and Cu conductors?
The CSV screw connectors and CSK screw cable lugs from BBC Cellpack are made from a tin-plated aluminum alloy. They can therefore be used for both Al and Cu conductors.
28Which screw-type cable lugs can be used for fastening to busbars?
The CSK screw cable lugs from BBC Cellpack are recommended for fastening to conductor rails because they are made of a tin-plated aluminum alloy and are therefore independent of the material of the conductor rail. Care must be taken during installation to ensure that the tin layer is not damaged.
29What is the tightening torque of the contact pin on the CWS 400 A plug?
The tightening torque is 30 Nm.
30Is the SRAT or SRBB heat-shrink tubing suitable for protecting busbars and shortening distances?
SRAT heat-shrinkable tubing can be used as wire insulation tubing for terminations and as protection against corrosion. It must not be used to protect busbars or to shorten the distances between these busbars. This function has not been tested and can therefore not be guaranteed.

Appropriate ventilation must be ensured during assembly. The required torque is specified in the respective installation instructions.
5Can the BBC Cellpack plugs with cable adapter be used in the open air (with UV radiation)?
The conductive, black outer sheathing of the base body is made of EPDM and the cable adapter is made of silicone. Both materials absorb UV radiation. Due to this absorption behavior, damage to deeper layers by UV radiation is not to be expected, so that the BBC Cellpack connectors can be used in the open air.
6Can any cone-shaped voltage sensor (IEC 61869-11) be used with the connectors (CTS, CTKS, CTS-S, CTKSA) from BBC Cellpack?
Yes, conical voltage sensors in accordance with IEC 61869-11 can be used with the connectors (CTS, CTKS, CTS-S, CTKSA) from BBC Cellpack. An additional set (order number 391083) is required for this and the maximum possible installation depth in the switch cabinet must be observed. The following table provides an overview of tested, compatible combinations.

6Can the screw cable lugs of the Cellplux connector family be used on a fine-stranded cable with a class 5 copper conductor?
Application is possible in accordance with the compatibility table. Please note that the cross-section range differs from the standard products.
7Can the screw cable lugs of the Cellplux connector family be used on a flex cable with a class 5 conductor (e.g.: PowerAmp-AMS)?
The screw cable lugs of the connector family are not suitable for use with flexible cables.
8Can type CSV screw connectors and type CSK screw cable lugs be used for Al and Cu conductors?
The CSV screw connectors and CSK screw cable lugs from BBC Cellpack are made from a tin-plated aluminum alloy. They can therefore be used for both Al and Cu conductors.
9Which screw-type cable lugs can be used for fastening to busbars?
The CSK screw cable lugs from BBC Cellpack are recommended for fastening to conductor rails because they are made of a tin-plated aluminum alloy and are therefore independent of the material of the conductor rail. Care must be taken during installation to ensure that the tin layer is not damaged.
10When is it advisable to use a counterholder?
During the assembly of screw connectors and screw cable lugs, forces occur that can no longer be compensated for by hand. As a result, deformations can occur that impair the function of the fitting. The use of a counterholder compensates for the leverage effect and ensures safe installation.
11What is the tightening torque of the contact pin on the CWS 400 A plug?
The tightening torque is 30 Nm.
12Which compression cable lugs and compression connectors can be used for conductor classes 5 and 6, fine and superfine stranded conductors (DIN/IEC 60228)?
Compression cable lugs to DIN 46235 and compression connectors to DIN 46267 are generally suitable for hexagonal crimping of conductor classes 5 and 6 (DIN/IEC 60228). In the case of BBC Cellpack's DK-CU-V compression cable lugs, this is verified by the DIN/IEC 61238 test standard.
13Which crimping pliers can be used for the DR and DR-L crimp connectors?
All crimping pliers for insulated connectors can be used.
14Which crimping pliers can be used for AVS wire connectors?
All crimping pliers can be used.
15Which impact wrenches are suitable for installing shear head screws?
For selection and installation with impact wrenches, please refer to the specification in the attached document.
16Which connectors can be used for connecting concentric conductors (Ceander, wire screen)?
Concentric conductors are arranged concentrically around the current-carrying cores in LV cables and act as a combined protective earth conductor (PE), neutral conductor (N) or shield. They can be designed as a Ceander or wire screen and do not have a fixed conductor shape. For concentric conductors, compression connectors tested in accordance with DIN 46267 can be used.
17How can AK screw-type branch terminals be used?
The AK screw-type branch terminals from BBC Cellpack are suitable for branching and connecting aluminum or copper conductors. To ensure that no parts are lost, it is advisable to open the AK terminal only after the cable ends have been prepared. To do this, the main conductor is stripped in the contact area without cutting the conductor. The conductor of the branch is also stripped at the end and then placed over the main conductor. To open the AK terminal, remove the contact screw and the upper plastic half. The AK terminal is installed in reverse order. However, it is not possible to combine Al and CU.
18How can FK overhead line clamps be used?
The FK overhead cable clamps from BBC Cellpack are suitable for branching and connecting copper conductors. To ensure that no parts are lost, it is advisable to open the FK clamp only after the cable ends have been prepared. To do this, the main conductor is stripped in the contact area without cutting the conductor. The conductor of the branch is also stripped at the end and then placed over the main conductor. To open the FK terminal, remove the nut. The FK terminal is installed in reverse order.
19How are compression cable lugs fitted?
Pressing takes place from the center hole (according to the markings) in the direction of the cable. Pressing makes the cable lug slightly longer. For this reason, a crimping allowance of 5mm (Cu) or 10mm (Al) is taken into account when preparing the cable. A suitable crimping tool in accordance with DIN is required for a DIN cable lug. The crimping insert is selected according to the outer diameter. In the case of a manufacturer-specific cable lug, the cross-sectional specification is usually used as the crimping insert.
20How are press connectors installed?
Pressing takes place from the center of the connector (according to the markings) in the direction of the cable. Pressing makes the compression connector slightly longer. For this reason, a pressing allowance of 5mm (Cu) or 10mm (Al) is taken into account when preparing the cable. A suitable crimping tool in accordance with DIN is required for a DIN connector. The crimping insert is selected according to the outer diameter. In the case of a manufacturer-specific connector, the cross-sectional specification is usually used as the crimping die.
21How is a BBC Cellpack screw connector with shear head screws (CSV, CSV-T, CSV-LHS) assembled?
For screw connectors with tear-off head screws, all screws must be tightened lightly one after the other during assembly. Then, for connectors with 2 screws per cable side, the screw to the cable is torn off first, followed by the screw to the center of the connector. For connectors with only one screw per cable side, tighten the screw evenly until it breaks off.
