35kV Cold Shrink Intermediate Joint

35kV Cold Shrink Intermediate Joint

Product Description

The 35kV Cold Shrink Intermediate Joint is a premium solution for seamlessly splicing medium-voltage power cables in underground networks, industrial complexes, and renewable energy systems. Utilizing pre-expanded silicone rubber components held under tension by removable support cores, this joint enables tool-free installation without the need for heat, flames, or specialized equipment. Its design integrates advanced stress control layers that ensure uniform electric field distribution across the splice, preventing partial discharge and maintaining electrical integrity. The joint's robust construction accommodates thermal cycling, mechanical vibrations, and environmental challenges, making it ideal for direct burial, duct, or trench applications where reliability and longevity are critical.

Engineered for exceptional performance, the joint features a multi-layer architecture including conductive and semi-conductive shields, insulation, and environmental seals—all pre-assembled into a single, compact unit. The high-grade silicone rubber material offers excellent resistance to moisture, UV radiation, chemicals, and temperature extremes (-50°C to +50°C), ensuring durability in harsh conditions. This cold-shrink intermediate joint is compatible with XLPE-insulated cables and supports a wide range of conductor sizes. Its innovative design not only simplifies installation but also reduces maintenance needs, providing a cost-effective and sustainable solution for modern power infrastructure.
