Heat-Shrink Cable Joint CellPack for 70–120 mm², 0.6/1 kV

CellPack Heat-Shrink Cable Joint for 70–120 mm², 0.6/1 kV is a prefabricated joining kit intended for medium-voltage single-core and multi-core power cables with conductor cross-sections from 70 to 120 mm². The kit uses heat-shrinkable tubing and molded components to restore electrical insulation, provide mechanical support and protect the cable joint against moisture and environmental contamination. It is designed for on-site jointing, repair and termination tasks where a compact, sealed connection is required.

Advantages

The heat-shrink system provides reliable dielectric recovery and consistent mechanical strength through controlled shrink ratios and adhesive-lined tubing that bonds to cable jackets. Installation reduces exposure of the conductor to environmental factors by creating a sealed interface between the cable cores and outer sheath. The kit is compatible with common medium-voltage cable constructions and supports standard crimped or bolted conductor terminations without requiring complex tooling beyond standard cable preparation and a heat source.

Suitable for

• On-site jointing of medium-voltage power cables (single-core and multi-core)
• Repairing damaged cable sections and restoring insulation
• Terminating cables for switchgear, transformers and distribution panels
• Industrial, utility and construction electrical installations

Key specifications

• Conductor cross-section range: 70–120 mm²
• Rated voltage: 0.6/1 kV
• Insulation and sealing: heat-shrinkable tubing with adhesive lining
• Mechanical protection: molded or reinforced shrink components to support joint area
• Compatible cable types: medium-voltage single-core and multi-core power cables
• Operational environment: indoor and outdoor use with environmental sealing

How to use

Prepare cable ends by cutting back outer sheath and insulating layers according to the kit instructions and remove any moisture or contaminants. Perform conductor connection using appropriate crimping or bolting methods and apply conductive screens or mastic where required. Position the heat-shrink components over the joint, ensuring correct sequence and overlap of adhesion layers. Using a controlled heat source, apply heat evenly to shrink the tubing and activate the adhesive, forming a sealed insulation and mechanical cover. Allow the joint to cool and inspect the finished assembly for complete sealing and uniform shrinkage.

Usage recommendations

Use a calibrated hot-air tool or propane torch with controlled technique to avoid overheating. Verify that cable dimensions and insulation types match the kit range before installation. Store the kit in a dry, temperature-stable environment and follow local electrical codes and safety procedures during jointing work.
