Heat-Shrink Cable Joint CellPack SMH 4 PL 5 for 150–240 mm², 0.6/1 kV

Heat-Shrink Cable Joint CellPack SMH 4 PL 5 for 150–240 mm², 0.6/1 kV is a prefabricated heat-shrinkable joint designed for medium-voltage single-core and multi-core power cables. The joint uses a heat-activated polymer sleeve to provide electrical insulation and environmental sealing for conductors with cross-sections from 150 to 240 mm², rated for 0.6/1 kV. It is intended for use in distribution networks for splicing, repairs and transition points where reliable insulation and moisture protection are required.

Advantages

The CellPack SMH 4 PL 5 joint delivers a uniform shrink fit that conforms to cable geometry when activated with controlled heating, creating a tight seal against moisture and contaminants while restoring dielectric protection. Its construction simplifies on-site installation by combining insulating and sealing functions into a single shrink sleeve system compatible with medium-voltage conductors. The design supports both single-core and multi-core applications within the specified conductor size range and is suitable for use in buried and aerial cable runs.

Suitable for

• On-site splicing of medium-voltage cables in distribution networks
• Repair of underground and overhead single-core or multi-core cables
• Creating transition points between different cable segments
• Applications requiring moisture-tight electrical insulation at 0.6/1 kV

Key specifications

• Conductor cross-section range: 150–240 mm²
• Voltage rating: 0.6/1 kV
• Heat-shrinkable polymer sleeve for electrical insulation and environmental sealing
• Suitable for single-core and multi-core medium-voltage cables
• Design suited to underground and overhead installations

How to use

Prepare cable ends by cutting, cleaning and arranging conductors according to standard splicing procedures, ensuring correct conductor alignment and any required metallic connectors are in place. Position the heat-shrink sleeve over the joint area and apply controlled heat evenly along the sleeve circumference until full shrinkage and sealing are achieved; use suitable heating equipment and follow safe working temperatures specified by the sleeve manufacturer. After cooling, verify that the sleeve has uniformly conformed to the cable profile and confirm electrical continuity and insulation resistance as per installation standards.

Usage recommendations

Use appropriate personal protective equipment and calibrated heating tools to achieve consistent shrinkage. Follow local regulations and industry standards for medium-voltage cable joints, and perform insulation and continuity tests after installation. Store the product in a dry, cool place away from direct sunlight to preserve the heat-shrink material until use.
