Heat-shrink cable joint CellPack 35–70 mm² 0.6/1 kV (model 7000011-48)

CellPack heat-shrink cable joint for 35–70 mm² conductors, rated 0.6/1 kV, is a preformed kit designed to restore electrical continuity and provide reliable insulation and environmental protection for medium-voltage power and distribution cables. The joint uses heat-shrinkable materials to create a compact, mechanically robust splice that resists moisture and contaminants. Intended for both indoor and outdoor use, the assembly offers long-term electrical insulation and mechanical reinforcement where conductors are joined, repaired or extended.

Advantages

The heat-shrink design provides uniform sealing and insulation around conductor splices, reducing the risk of water ingress and corrosive damage. Materials used in the kit improve mechanical protection of the splice and contribute to stable dielectric properties at the rated voltage. The kit is suitable for field application, enabling relatively fast installation with common heating tools. Its compact form factor minimizes added bulk at the joint while preserving conductor flexibility and routing.

Suitable for

• Repairing damaged medium-voltage cables (0.6/1 kV) with 35–70 mm² conductors
• Splicing and extending distribution and service cables in indoor and outdoor installations
• Creating insulated joints where moisture resistance and mechanical protection are required

Key specifications

• Conductor range: 35–70 mm²
• Rated voltage: 0.6/1 kV
• Heat-shrinkable insulating material for sealing and electrical insulation
• Environmental protection against moisture and contaminants
• Compact mechanical reinforcement for splice area

How to use

Prepare cable ends by cutting, stripping insulation and cleaning conductors according to safe working practices and applicable standards. Position the heat-shrink components over the prepared conductors, arrange the electrical connection or crimped joint, then slide the kit elements into place to cover the splice and insulation overlap. Apply controlled heat using an appropriate heat gun or torch until the shrink material conforms to the cable profile and seals uniformly. Allow the joint to cool before subjecting it to mechanical load or electrical testing.

Usage recommendations

Follow local electrical codes and safety procedures during installation. Use suitable personal protective equipment and approved heating tools. Verify conductor compatibility and perform post-installation checks such as visual inspection and, if required, insulation resistance measurement to confirm correct sealing and electrical integrity.
