Cable Terminal Kit Cold Shrink Tube For Power Cable Termination For Cable Joint Shrink Tube Grip

The Cold Shrink Cable Terminal Kit is a high-performance insulation and sealing solution designed for medium and high-voltage power cable termination and joint applications. It uses pre-expanded silicone rubber tubing with an internal support core, which contracts automatically after installation to provide consistent pressure, reliable sealing, and long-term electrical stability.

This product is widely used in power distribution systems, underground cable networks, and industrial electrical installations where safety, durability, and fast installation are required.

Product Features

1. Advanced Cold Shrink Technology (No Heat Required)

The tube is pre-stretched and mounted on a removable plastic spiral core. During installation, the core is simply pulled out, allowing the silicone rubber tube to shrink evenly around the cable or joint area. This eliminates the need for heat guns or open flames.

2. High Elastic Silicone Rubber Material

Manufactured from premium-grade silicone rubber, the tube provides:

• Excellent electrical insulation
• Strong UV and ozone resistance
• Long-term aging stability
• High elasticity for tight cable grip

3. Reliable Cable Joint Sealing Performance

The shrink tube creates a constant radial pressure on the cable surface, ensuring:

• Moisture-proof sealing
• Dust and corrosion protection
• Stable mechanical protection at cable joints

4. Wide Application Compatibility

Suitable for:

• Power cable termination systems
• Cable joint / straight-through splice protection
• Medium-voltage XLPE cable accessories
• Indoor and outdoor installation environments

5. Fast & Safe Installation

No flame, no heating, no special tools. Installation is faster and safer, especially in confined or hazardous environments such as substations or underground cable trenches.

FAQ

Q1: What is a cold shrink cable termination tube?

It is a pre-expanded silicone rubber tube mounted on a removable core. Once installed, it shrinks automatically to form insulation and sealing around cables or joints.

Q2: Can it be used for both cable termination and cable joints?

Yes. It is designed for both end termination protection and straight-through cable joint sealing applications.

Q3: What voltage levels does it support?

Depending on design, it can be used from low voltage (1kV) up to medium/high voltage systems (up to 35kV).

Q4: Is special installation equipment required?

No. Only basic cable preparation tools are required. No torch, heat gun, or electrical heating equipment is needed.

Q5: How long is the service life?

Under standard operating conditions, the service life typically exceeds 20 years.

Q6: Can it be used outdoors?

Yes. The silicone rubber material provides strong UV resistance, weather resistance, and waterproof performance, making it suitable for long-term outdoor use.
