Heat shrinkage ratio: that is, the diameter ratio of the heat shrinkable tube before and after shrinkage.
In the installation of power engineering, the cable termination kits and the joint kits are important power equipment components in the power transmission and transformation cable line. Its role is to disperse the electric field at the external shielding of the cable termination, maintain the cable from being broken down, and have internal and external insulation and waterproof effects.
Constant force springs are an essential component in heat shrink cable accessories, providing constant tension to minimize cable stress and create durable, lasting connections.They provide reliable long-term performance even as materials expand/contract with temperature changes. When paired with adhesive lined heat shrink tubing, environmental sealing is enhanced.
he termination kit of the cold shrinkable cable accressories and the cold shrinkable straight through joint kit are vulcanized and molded by injection of elastomer materials (commonly used silicone rubber and ethylene propylene rubber) in the factory, and then expanded and lined with plastic spiral supports to form various cable accessories.
Heat shrinkable tube is a kind of insulation sleeve with high temperature shrinkage, soft flame retardant, insulation and corrosion prevention function, which is widely used in various wire harnesses and inductors insulation protection.
The material of cold shrinkable cable accessories is mainly silicone rubber, and the material of heat shrinkable cable accessories is mainly PE, from the point of use, cold shrink cable accessories are more convenient, heat shrinkable cable accessories need heating installation, more complex than cold shrinkable cable accessories.
