Wires and cables are divided into copper and aluminum core cables according to different conductors. There are more common copper core cables in our daily life, because it is widely used, but a lot of people are not familiar with copper core cables.

During the storage period, the cold shrinkage parts will not have obvious permanent deformation or elastic stress relaxation, otherwise, after installation on the cable can not ensure enough elastic compression force.

Poor waterproof sealing of cable accessories will cause failure. Through incomplete statistics, there are obvious traces of water in the cable accessories accounting for 71%. It can be seen that the waterproof sealing of cable accessories is extremely important.

Cable sheath is a protective layer covering the cable insulation layer, cable sheath and conductor, insulation layer collectively referred to as the three components of the cable. Typical sheath structure, including inner sheath and outer sheath.

Insulation tubes are divided into two kinds of raw materials. One kind of raw material is heat shrinkable insulation tube, the other kind of raw material is cold shrinkable insulation tube. Let's see the difference between these two raw materials.

Cold Shrinkable Cable Accessories Compared with Heat Shrinkable Cable Accessories, cable accessories that do not require the use of heating tools for construction and can be installed at room temperature. The Cold Shrinkable Cable Accessory is made of imported liquid silicone rubber.
