With years of experience in the electrical industry, we provide professional solutions including Cable accessories, Cable distribution boxes, ring main units, Prefabricated Substations, combination transformers, SF6 load switches, and Vacuum circuit breakers.

Among our Cable Accessory products, the JH LSJ 10KV cold shrink intermediate joint is designed to provide a safe, stable, and long-lasting connection solution for medium voltage cable systems. We understand that cable joints are critical points in power networks. A small problem in a cable connection may influence the operation of the whole electrical system.

Therefore, we developed this 10KV Cold Shrink Cable joint by combining reliable insulation materials, advanced cold shrink technology, and strict manufacturing processes. Our goal is simple: help customers build safer power systems with products that are easy to install, stable during operation, and suitable for different environments.

Product Overview of JH LSJ 10KV Cold Shrink Intermediate Joint

The JH LSJ 10KV cold shrink intermediate joint is a medium voltage cable accessory used for connecting two sections of 10kV power cables. It is mainly applied in underground cable systems, industrial power distribution networks, renewable energy projects, and infrastructure facilities.

Unlike traditional cable jointing methods that may require heating tools, our cold shrink intermediate joint uses pre-expanded elastic insulation technology. During installation, technicians only need to remove the support core, and the silicone rubber body automatically contracts around the cable connection area.

This design creates continuous pressure and reliable sealing performance, helping prevent moisture, dust, and external environmental factors from affecting the cable connection.

For customers looking for a reliable 10KV cable joint kit, the JH LSJ series provides a practical solution that balances safety, installation efficiency, and long-term performance.

How Does a Cold Shrink Intermediate Joint Work?

The working principle of the JH LSJ 10KV cold shrink intermediate joint is based on the natural elastic recovery force of silicone rubber materials.

Before delivery, the insulation tube and stress control components are expanded and placed on a removable support core. During installation, the cable ends are prepared and connected according to technical requirements. After positioning the joint body, the support core is removed.

The silicone rubber material then shrinks evenly around the cable surface, creating a tight connection between the cable insulation layer and the joint body.

This process provides several important functions:

• Maintains stable electrical insulation performance

• Controls electric field distribution around the cable joint

• Provides moisture-proof sealing protection

• Improves mechanical strength of the connection area

• Supports long-term operation in outdoor and underground environments

Because the installation process does not require flame heating, cold shrink technology reduces installation risks and improves working efficiency, especially in projects where construction conditions are limited.

Main Features of JH LSJ 10KV Cold Shrink Intermediate Joint

1. Excellent Electrical Insulation Performance

Electrical insulation is one of the most important requirements for Medium Voltage Cable Accessories. Our 10KV cold shrink intermediate joint uses high-quality insulation materials designed to maintain stable electrical performance during long-term operation.

The internal structure helps reduce electric field concentration and improves the reliability of cable connections. This makes the product suitable for power distribution systems that require continuous and safe operation.

2. Strong Sealing and Waterproof Protection

Cable joints are often installed underground or outdoors, where they may face rainwater, humidity, soil moisture, and temperature changes.

The JH LSJ 10KV cold shrink cable joint provides reliable sealing performance through elastic compression. The tight connection between components helps prevent water and contaminants from entering the cable joint area.

This protection helps extend the service life of cable systems and reduces maintenance requirements.

3. Simple Installation Process

One of the biggest advantages of cold shrink technology is easy installation. Traditional methods may require heating equipment and experienced operators to control temperature during installation.

Our cold shrink intermediate joint removes this requirement. The installation process is faster, cleaner, and safer, which helps contractors reduce project time and improve construction efficiency.

4. Excellent Environmental Adaptability

Power systems are installed in many different environments, including cities, industrial areas, renewable energy sites, and underground networks.

The JH LSJ 10KV cable intermediate joint is designed to maintain reliable performance under changing conditions. The product provides good resistance against temperature variation, humidity, and outdoor environmental stress.

Technical Advantages of Our 10KV Cable Joint Solution

When we design cable accessories, we focus on practical project needs. A good cable joint should not only work well during installation but also remain reliable after years of operation.
