Material Selection And Elastic Recovery Mechanism Of Cold Shrink Cable Accessories

Liquid silicone rubber is the core material of Cold Shrink Cable Accessories. This imported material is injection-cured at the factory to form a polymer structure. Silicone rubber's high dielectric strength and low dielectric loss characteristics ensure its stability under voltage stress. The material's molecular structure is not easily broken, allowing it to withstand electric fields for extended periods without breakdown.

The cold-shrink accessory is pre-supported by an internal plastic spiral structure, allowing it to adhere tightly to the cable at room temperature using elastic restoring force. This mechanism ensures uniform stress on the insulation layer, avoiding thickness variations caused by uneven heating in heat-shrink products. Constant radial pressure maintains a tight contact between the insulation layer and the conductor shield, significantly reducing partial discharge; its partial discharge performance is far superior to that of heat-shrink products.
