Heat Shrink Cable Termination Kit (High Voltage Power Cable Accessory)

The Heat Shrink Cable Termination Kit is a widely used solution for medium and high-voltage power cable termination systems. It uses radiation-crosslinked polymer materials that shrink when heated, forming a tight insulation and sealing layer around the cable. The product is designed for XLPE power cables and provides reliable electrical performance in both indoor and outdoor environments.

This type of termination is commonly used in substations, industrial power systems, and distribution networks where cost-effectiveness and proven installation methods are required.

Product Features

1. Heat-Activated Shrink Technology

The termination tube is made from pre-expanded cross-linked polyolefin material. When heated using a hot air gun or flame tool, it shrinks uniformly to tightly wrap the cable surface, ensuring strong insulation and mechanical protection.

2. Reliable Electrical Insulation Performance

Designed with high dielectric strength materials, the kit provides stable insulation performance under medium and high voltage conditions, reducing the risk of partial discharge and electrical breakdown.

3. Integrated Stress Control Design

Equipped with stress control components such as stress cones or mastic layers, it helps optimize electric field distribution at the cable termination point, improving long-term operational stability.

4. Strong Environmental Resistance

The outer layer offers resistance to moisture, UV radiation, and chemical corrosion, making it suitable for both indoor and outdoor installation environments.

5. Cost-Effective Installation Solution

Compared with cold shrink systems, heat shrink termination kits offer a more economical solution for large-scale power distribution projects.

FAQ

Q1: What is a heat shrink cable termination kit?

It is a cable accessory that uses heat-shrinkable materials to form insulation and sealing protection at cable termination points after heating.

Q2: What tools are required for installation?

A hot air gun or controlled flame torch is required to evenly heat and shrink the material onto the cable surface.

Q3: What voltage levels is it suitable for?

It is commonly used for low voltage up to 35kV medium/high voltage cable systems.

Q4: Can it be used outdoors?

Yes. It is designed with UV-resistant and waterproof materials suitable for outdoor substations and distribution systems.

Q5: What is the difference between heat shrink and cold shrink termination?

Heat shrink requires heating for installation, while cold shrink uses a pre-expanded elastic tube that shrinks automatically without heat. Heat shrink is more economical; cold shrink is faster and safer.
