Application of liquid silicone rubber in cable accessory industry

2023-03-02

In the early days, people used ethylene propylene rubber to process the electric stress control cone and intermediate joint. The advantage of ethylene propylene rubber is the high insulation performance of the material. At the same time because of the emergence of new silicone rubber materials, cable accessories manufacturers have adopted silicone rubber to manufacture cable termination electric stress control cone and integral prefabricated straight through joint.

The processing property of solid high temperature vulcanized silicone rubber has been greatly improved than that of ethylene propylene rubber. In recent years, the appearance of liquid high temperature vulcanized silicone rubber has provided the basic conditions for us to manufacture high performance cable termination electric stress control cone and integral prefabricated straight through joint. Especially for cold shrinkable cable accessories as a raw material of liquid silicone rubber role is more obvious.

Because liquid high temperature vulcanized silicone rubber not only has excellent insulation performance, but also has good processing performance, its flow performance is very good, take this material processing cable terminal electric stress control cone and the whole prefabricated type of intermediate joint, insulating silicone rubber can smoothly flow to the mold cavity of each small narrow area.

It can maintain a precise R surface transition between the conductive cone (conductive tube), form a neat interface, and the conductive cone (conductive tube) is closely bonded and well combined. The closer the adhesion between the insulating silicone rubber and the conductive silicone rubber, the smaller the interface residual air gap, the better the electrical performance between the stress control cone and the intermediate connector and the cable insulation set.
