There are many types of cable jacket or sheathing. The compatibility of connectors and adaptability to the environment should be taken into account in the selection of raw materials for cable sheathing.
The silicone grease used in cold shrinkable cable accessories is a kind of insulating lubricating silicone grease made by special process by modifying silicone oil, ultra-pure insulating filler and adding functional additives.
At present, the cold shrinkable tube on the market is mostly made of silicone rubber and EPDM material. EPDM has the advantage of being "seen as a more durable rubber than silicone" (again citing organosilicone engineering).
The basic requirements of Cold Shrinkable Cable Accessories are to effectively control the electric field strength at the break of insulation shield, reliable sealing and complete insulation protection to the external environment, adequate mechanical strength, and good conductor connection.
Busbar box are mainly used for insulation protection at live connection of electrical equipment, as well as for insulation of special parts such as complete sets of switchgear, substations, circuit breakers and transformer terminals.
Heat shrinkable tube is usually used for wire insulation, encapsulation and protection. It can be tightly wrapped around wire or cable by heat shrink to improve its insulation performance. Different application scenarios require different materials of heat shrink tubes.
