Product Description

The intermediate joint adopts a three-layer waterproof sealing process to ensure excellent sealing and moisture-proof performance.


Product Description

Full Cold Shrinkage Technology: No need for hot work and special tools, nor the trouble of gradually inserting. Just gently pull out the core rope, and it will rely on its own elastic retraction to tightly adhere to the cable, completing the installation.

Reliable insulation: Imported liquid silicone rubber is used to ensure excellent insulation and high recovery elasticity. After installation, it always provides constant and lasting radial pressure to the cable body, with a small amount of partial discharge, and "breathes with" the cable body.

Good sealing performance: The intermediate joint adopts a three-layer waterproof sealing process, with excellent sealing and hydrophobicity, ensuring excellent elastic sealing and moisture-proof performance of the accessories.

Easy installation: simple installation, low technical dependency on operation, short stripping distance during cable preprocessing, and small installation space required. The grounding adopts a constant force spring process, which eliminates the need for welding or copper binding, making it faster and more reliable.

Widely used: anti pollution, aging resistance, good hydrophobicity, corrosion resistance and UV resistance, ensuring stable long-term performance. With excellent cold resistance, it is particularly suitable for high altitude areas, cold areas, humid areas, salt fog areas, and heavily polluted areas.
