Cable accessories:10~35kV Silicon Rubber Precast Cold Shrinkable Intermediate Joint [Clicked:148] 

 

10~35kV Silicon Rubber Precast Cold Shrinkable Intermediate Joint
General
10~35kV Silicon Rubber Precast Cold Shrinkable Intermediate Joint is an upgraded product of cable accessories made by our company to meet the need of the technique development of power distribution system and the requirement of customers. Precast cold shrinkable technique is introduced into this serial product. The products with convenient installation, using high dielectric capacity material, can improve the stress distribution in the electric field. Once using this product, the safety and reliability of the circuit can be improved. It is used to intermediate connect packed insulated power cable and is the first-choice product for power plant, large factory field and distribution system of some great programs.


Product Features

a.Using high quality organic silicon rubber imported from abroad. Possessing the characteristic of perfect electrical insulativity and tracking resistance and electric corrosion resistance.
b.With good hydrophobic capacity, possibility to transplant filth, and high dielectric strength.
c.Working ambient temperature(-50ºC--+200ºC).
d.Using stress control material with special prescription, and possessing excellent electric field stress control capability.
e.Adopting precast technique,so the installation is very convenient, without using special tools.
