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.
heat shrink cable accessories and cables are integrated, after cooling can obtain high mechanical strength, can resist quite high pressure, and can be sealed waterproof; In addition, an iron shell protective layer is designed and installed at the underground connection interface to further increase its mechanical strength, wear resistance and water resistance.
There are many scientific research achievements in the temperature monitoring of wire and cable joints in the world, which are distinguished by data signal collection methods, and the key is electronic signal measurement and optical signal temperature measurement.
A wide variety of cable accessories, each cable accessories have different characteristics and different types of product characteristics and limitations, cable accessories between the varieties can not replace each other. In general, outdoor refers to open-air wire and cable accessories, while indoor refers to the connection between cables and electrical equipment.
