At Jihui Electric Group Co., Ltd., we focus on providing reliable medium and low voltage power transmission and distribution equipment up to 35kV. Located in Yueqing Economic Development Zone, China, we specialize in the research, development, manufacturing, sales, and service of electrical products for global power applications.

Our product range includes Cable accessories, Cable distribution boxes, ring main units, Prefabricated Substations, combination transformers, SF6 load switches, and Vacuum circuit breakers. Among our Cable Accessory solutions, the JH LS 10KV Cold Shrinkage Terminal Insulation Tube is designed to provide safe, stable, and efficient insulation protection for medium voltage cable termination systems.

From our experience working with electrical projects, we know that cable accessories are not just small components. They directly affect the safety and service life of the whole power system. A weak insulation connection may cause unexpected failures, while a reliable insulation tube can help maintain stable operation for many years.

That is why we developed the JH LS series using advanced cold shrink technology, high-quality silicone rubber materials, and strict manufacturing control. Our purpose is simple: help customers build safer and more reliable power networks.

Product Overview of JH LS 10KV Cold Shrinkage Terminal Insulation Tube

The JH LS 10KV Cold Shrinkage Terminal Insulation Tube is a professional cable accessory designed for 10KV medium voltage cable termination applications. It provides insulation protection, sealing performance, and mechanical protection for cable connection areas.

This product is widely used in power distribution systems, industrial electrical networks, renewable energy projects, underground cable systems, and infrastructure construction.

Unlike traditional insulation solutions that require heating equipment, cold shrink technology uses pre-expanded elastic insulation materials. During installation, technicians only need to position the insulation tube correctly and remove the support core. The silicone rubber material then automatically contracts and creates continuous pressure around the cable.

This simple installation method helps reduce installation errors and improves working efficiency, especially in outdoor environments where construction conditions may be challenging.

Why We Developed Cold Shrinkage Terminal Insulation Tube

During our years in the electrical equipment industry, we have worked with customers from different countries and industries. We noticed that cable termination systems often face similar challenges:

• Moisture entering the cable connection area

• Insulation aging caused by environmental conditions

• Installation quality differences between workers

• Limited construction space and difficult installation conditions

The JH LS 10KV Cold Shrinkage Terminal Insulation Tube was developed to solve these practical problems.

By using elastic silicone rubber materials and cold shrink installation technology, our product provides stable insulation pressure and reliable protection without complicated installation procedures.

Working Principle of JH LS 10KV Cold Shrinkage Terminal Insulation Tube

The working principle of our cold shrink insulation tube is based on the natural elastic recovery ability of silicone rubber.

During production, the insulation tube is expanded and installed on a removable support core. Before installation, the product maintains its expanded shape. When the technician completes cable preparation and removes the support core, the insulation tube shrinks automatically.

The shrinking process creates continuous radial pressure around the cable surface, forming a tight insulation layer.

This structure provides several important functions:

• Improved electrical insulation performance

• Reduced risk of moisture penetration

• Better cable connection protection

• Stable operation under changing temperatures

• Long service life in outdoor environments

Because the installation does not require flame or heating tools, cold shrink technology provides a safer and cleaner installation method compared with some traditional solutions.

Main Features of JH LS 10KV Cold Shrinkage Terminal Insulation Tube

1. High-Performance Silicone Rubber Material

The insulation material plays a key role in cable accessory performance. Our JH LS 10KV cold shrinkage terminal insulation tube uses high-quality silicone rubber with excellent flexibility and insulation characteristics.

The material can maintain stable performance under different environmental conditions, helping the cable system operate safely for a long time.

2. Reliable Electrical Insulation Protection

Medium voltage cable systems require strong insulation protection because they operate under continuous electrical stress.

The JH LS insulation tube helps improve electric field control around the cable termination area and reduces the possibility of insulation breakdown caused by uneven electrical stress.

3. Excellent Sealing Performance

Moisture is one of the major causes of cable accessory problems. Outdoor cable systems may face rain, humidity, dust, and temperature changes.

Our cold shrink terminal insulation tube provides a tight sealing structure that helps prevent water and contaminants from entering the cable connection area.

4. Easy Installation Without Heating Equipment

One of the biggest advantages of cold shrink technology is installation convenience.

Traditional heat shrink products require heating tools and careful temperature control. The JH LS cold shrink insulation tube only requires mechanical installation, reducing installation complexity.

This helps contractors save installation time and improve construction safety.
