Located in Yueqing Economic Development Zone, China, we specialize in the research, development, manufacturing, sales, and service of electrical equipment including Cable accessories, Cable distribution boxes, ring main units, Prefabricated Substations, combination transformers, SF6 load switches, and Vacuum circuit breakers.

Among our professional Cable Accessory solutions, the 35KV three core cold shrink terminal cable is designed for safe and stable termination of medium voltage three-core power cables. It is widely used in electrical distribution networks, industrial facilities, renewable energy projects, and infrastructure systems where reliable cable connection performance is required.

From our experience working with different power projects, we understand that cable termination is a critical point in electrical systems. A good cable terminal must provide strong insulation, reliable sealing, mechanical protection, and long-term operation stability.

For this reason, we developed our 35KV Cold Shrink Cable termination solution using advanced materials and strict manufacturing processes. Our purpose is not only to provide a product but also to help customers build safer and more efficient power networks.

Product Overview of 35KV Three Core Cold Shrink Terminal Cable

The 35KV three core cold shrink terminal cable is a medium voltage cable termination accessory designed for connecting and protecting three-core 35kV power cables.

The main function of this product is to restore the insulation structure after cable termination and provide protection against external environmental conditions.

Compared with traditional cable termination methods, cold shrink technology offers a simpler installation process. It does not require heating equipment, which reduces installation risks and improves working efficiency.

Our product is suitable for:

• 35KV power distribution systems

• Underground cable networks

• Industrial electrical facilities

• Renewable energy projects

• Commercial and infrastructure buildings

The design combines electrical insulation, stress control, sealing protection, and mechanical strength to ensure stable cable operation.

Why We Developed 35KV Cold Shrink Terminal Cable

During our years of manufacturing electrical equipment, we found that many power system problems come from cable connection points. Even when the cable itself has excellent quality, improper termination may affect system reliability.

Customers usually need cable accessories that can handle:

• Continuous electrical stress

• Temperature changes

• Outdoor humidity and moisture

• Mechanical impact during operation

• Different installation environments

Based on these practical requirements, we developed the 35KV three core cold shrink terminal cable with three main goals:

• Improve electrical safety

• Increase installation convenience

• Provide long-term protection

We believe a reliable cable termination product should help customers reduce maintenance problems and improve the overall stability of power systems.

Working Principle of 35KV Three Core Cold Shrink Terminal Cable

The working principle of cold shrink technology is based on the elastic recovery performance of special silicone rubber materials.

During manufacturing, the insulation tube is expanded and installed on a removable support core. Before installation, the product maintains its expanded shape.

After the cable preparation process is completed, the technician places the cold shrink terminal in the correct position and removes the support core.

The silicone rubber then naturally contracts and creates continuous pressure around the cable surface.

This pressure provides:

• Stable insulation contact

• Electric field control

• Moisture sealing

• Mechanical protection

Because no external heating is needed, installation quality is less affected by weather conditions and construction environments.

Main Features of 35KV Three Core Cold Shrink Terminal Cable

1. Excellent Electrical Insulation Performance

For a 35KV cable termination, insulation performance is the most important factor. Our cold shrink terminal cable uses high-performance insulation materials designed to maintain stable electrical characteristics.

The insulation structure helps control electrical stress and improves system reliability during long-term operation.

2. Strong Environmental Protection

Cable terminals are often installed in complex environments, including underground systems, outdoor areas, and industrial locations.

Our product provides reliable sealing protection against moisture, dust, and environmental changes.

3. Easy Installation Without Heating Tools

Traditional heat shrink products require heating equipment and skilled operation. Cold shrink technology simplifies the installation process.

Technicians can complete installation without flame or heating tools, improving safety and efficiency.

4. Stable Long-Term Performance

The elastic silicone rubber structure maintains constant pressure on the cable surface, helping the product keep reliable performance during long service periods.

5. Suitable for Multiple Medium Voltage Applications

The 35KV three core cold shrink terminal cable is designed for various medium voltage systems, including power utilities, industrial plants, renewable energy facilities, and infrastructure projects.
