End joints and branch joints for medium voltage are not included in the BBC Cellpack product range.

Heat shrinkable components are components that shrink back to their original production state when heat is applied, such as spreader caps, end caps, hoses, or sleeves. A hot-air blower can be used for shrinking. The heat input, however, is lower compared to a gas burner. This prolongs the duration of the shrinking process. The settings and nozzle must be individually selected depending on the hot-air blower used. It is important to make sure that the surface of the shrinkable tube is not burned.

If it is a hose with hot melt adhesive (SRH...), the adhesive will slowly flow out at both ends. Uniform wall thicknesses and straight labelling are important indicators for correct shrinkage.

The test adapters are exclusively intended for use in threaded shielded T-shaped EPDM cable connections of the types CTS and CTKS. It is not allowed to use the screw inserts in cable connectors from other manufacturers.

It has to be remembered that the cable cross-section and minimum diameter across the insulation falls within the specified range for the set. The reverse is excluded. In most cases, the applicable system voltages are specified in the documentation available and provided.

The contact pin can be removed with a long socket, which makes it possible to reuse it. We recommend using an additional set, because the surfaces are both cleaned and the lubricant GM1 must be reused. It is also important to ensure appropriate air-release during installation on the feed-through and the termination insert. The required torque is available on request.

It can be used according to the compatibility table. The cross-sectional area deviates from the current standard products.

Download Overview

The screw cable lugs of the connector product range are not suitable for this application. This type of cable is very special and requires deeper inspection for suitability.

The responsible person in the network is responsible for deciding whether a cable sheath can be repaired. This depends on the damage and the properties the cable sheath satisfies. In general, a cable may only be repaired with a sleeve if the damage affects only the outer cable sheath. If additional damage to the core insulation is detected, repairs by means of a sleeve are not permitted. The cable must then be repaired as a complete system, either with additional insulating and sealing components over the damaged core(s) or, if necessary, by installing a straight-through joint over the damaged cable section.

If it decided to use shrinkable sleeves, the sleeve should be selected according to the values mentioned in the catalogue. The operating voltage of the cable is not the deciding factor when selecting the right sleeve. The function of sleeves is described as follows - restoration of the outer cable sheath in its three functions insulation, protection against moisture and mechanical protection.

Cellpack SR(H), SRAT, SRBB hoses do not contain chlorine (or any other halogen-containing materials), sulphur, heavy metals or substances that are hazardous to health. A corresponding RohS and Reach conformity confirmation is available for the respective component.

Conductive outer layer of the body of EPDM absorb UV radiation and, in most cases, there is UV-exposure which leads to partly surface aging at the border of material with outside atmosphere. Due to this feature of the material, damage of deeper layers through UV-exposure is not expected. The usage of UV-stabilized PVC band (No. 228 or No. 328) on the cable entry is recommended.

Conductive outer layer of the body of EPDM absorb UV radiation, due to this feature of the material, damage of deeper layers through UV-exposure is not expected. Cable adapter made of EPDM is allowed for outdoor usage.

No, this is not recommended. The lubricants are assigned to specific cable accessories. Most have electrical properties in special areas (e.g. dissipation factor or dielectric constant). A standardisation is not possible.

Yes, BCC Cellpack cable accessories can be used with the cable with (H)EPR insulation, but the highest permissible temperature on the conductor during continuous operation must not exceed 90°C (according to HD 620, IEC 60502-2).

Yes, CHE/CAE cable terminations can be used with class 5 & 6 conductors according to the cross-section ranges specified in the data sheet. Use cable lugs that are suitable for this class of conductor. CHESK/CAESK cable terminations are differentiated from CHE/CAE by the screw cable lug in the kit. They may not be used with class 5 & 6 conductors.

Yes, joints can be used with class 5 and 6 conductors according to the cross-section ranges specified in the data sheet. Use compression connectors that are suitable for this class of conductor. CHM joints are different from CHMSV due to the screw connector in the kit. They cannot be used on conductor class 5 and 6.

The SRAT heat shrinkable tube can be used as a core insulating tube for end closures 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. It cannot be guaranteed. The SRBB hose is the right solution for this application.

Deposits in the form of uniform crystallisation on the inner surface of EPDM insulating bodies are process-related degradation products of the peroxide used in the manufacturing process.

There are no negative findings on effects of such crystallisation that would impair the function of the device. Depending on storage temperatures and duration, these crystal formations can occur on all surfaces. In case of very strong crystallisation, we recommend wiping the inner surfaces as part of the inspection and cleaning process prior to assembly in order to avoid influences when screwing in the insulating terminations or placing the insulating body on the entry point.

The nominal voltage of a cable is the voltage for which the cable is designed and includes the operating characteristics and testing requirements. Based on DIN VDE 0298-3, the nominal voltage is expressed in volts by the ratio of two values U_o/U.

The following applies:

U_o – the rms value of the voltage between an outer conductor and earth (metallic sheath / screening of the cable), conductor-earth voltage.

U – the rms value of the voltage between two outer conductors of a multi-core cable or a system of single-core cables, conductor-to-conductor voltage.

In an AC system, the nominal voltage of a cable must be at least equal to the value for U_o and U of the system. In addition, the IEC regulations also specify the highest permissible voltage U_m (maximum voltage) in brackets U_o/U (U_m). BBC Cellpack products are labelled with the maximum permissible voltage U_m.

The calculated possible voltage on capacitive measuring point is between 0,08 … 0,5 U_o, depending on capacity ratio (conductor to measuring point and measuring point to earth).

In any case, even minimum at 6/10(12)kV , voltages can be reached up to 500V. So open measuring point is always dangerous to life!

Since measuring is object of system operator, BBC Cellpack do not have safety procedure beside normal safety procedure for handling of electrotechnical equipment. It must be clear that the voltage on measuring point is dangerous.

BBC Cellpack Electrical Products has been selling cable accessories for low and medium voltage applications for more than 40 years. Based on feedback from our customers and their records, as well as the very low number of complaints, it can be stated that safe operation of our cable accessories for low voltage and medium voltage applications is achievable for a period of more than thirty years.

Important note on warranty:

BBC Cellpack Electrical Products is only supplying components (kit) with installation instructions describing their assembly steps. The assembly of the cable accessories itself is not carried out by BBC Cellpack, but by the customer or an assembly company appointed by the customer. In general, in accordance with legal requirements, BBC Cellpack Electrical Products can only provide warranty for the components (kit) supplied, but not for the assembled cable accessories, as BBC Cellpack Electrical Products has no necessary influence on the quality of cable preparation and assembly of the cable accessory or their operation in the network. The cable accessories are free from material defects if they are suitable for the use stipulated in the contract at the time of handover to the customer. The specification of the expected lifetime does not represent a guarantee, assurance, quality agreement or other commitment binding on the seller and also does not represent an extension of the warranty period beyond the warranty within the framework of the statutory periods.

Description of various factors influencing the service life of cable accessories:

There are several factors that can negatively affect the service life of a cable accessory. In our experience, these include normally and not exclusively cable preparation and assembly, network operation or the network conditions themselves, as well as the storage of the kit or the temperature at which the installation is carried out. Due to the many possible influencing factors, this list does not claim to be complete. A legally binding general statement on the service life by BBC Cellpack Electrical Products is therefore not possible and will not be given by us. Influence of cable preparation and assembly on the service life of cable accessories: Basic requirement to achieve the lifetime are careful and clean cable preparation in accordance with the state of technology, but also careful and conscientious compliance with the work steps specified in BBC Cellpack installation instructions. In addition to this requirement, only components supplied from the manufacturer as part of the kit or recommended or approved by the manufacturer, for example connectors qualified according to IEC61238, may be used for proper installation and function of the product. For proper installation as a prerequisite for a long service life, user training is recommended for new products or technically complex solutions.

Influence of network operation or network conditions on the service life of cable accessories:

The service life of a product always depends on the conditions of the power supply network acting on the product. BBC Cellpack Electrical Products cable accessories are type-tested in the low-voltage range in accordance with or based on the EN50393 standard, and in the medium-voltage range in accordance with or based on the HD629 standard. Electrical, mechanical or thermal stresses exceeding the requirements of these standards may have significant effects, i. e. lead to a reduction in the service life of the cable accessories. Thus, no estimate of the possible or remaining service life can be made if, for example, effects of short circuits or transient voltage increases due to switching operations or lightning surge voltages have occurred. The application of the aforementioned standards is not legally binding. However, even if all standards are applied, not all of the influencing factors that may affect the service life of cable accessories are conclusively.

Influence of the storage conditions of the delivered product as well as the temperature during installation on the service life of cable accessories:

In the question of proper storage conditions, a distinction must be made according to the technology used: Components and products using cast resin, gel or cold shrink technology or other cold-applied products may be subject to restrictions on storage time, restrictions on storage conditions or recommendations on installation conditions. Corresponding information on the maximum permitted storage time, the recommended storage conditions and the recommended temperature range for assembly can be found in the product documentation and is also listed in brief form on the product label/label.

The tightening torque is 30Nm.

Shielded plug or screw cable connectors with and without metal housing are earthed materials that can be safely touched during fault-free operation if they have been earthed and installed properly.

We generally recommend not touching any live separable cable connectors as it is not always apparent from the outside of they are operating properly.
