cold shrink cable accessories and heat shrinkable cable accessories performance:

1, making the difference between raw materials: shrink cable accessories used raw material is a silicon rubber; heat shrinkable cable accessories used raw material is polyethylene.

2, cable accessories structure difference: cold shrink cable accessories will be stress cone, outer insulation protection pipe and an umbrella skirt as a whole; heat shrinkable cable accessories using stress control tube, insulation protection tube and umbrella skirt etc. alone produced supporting construction.

3, ground connection way of difference: shrink cable accessories using the spring constant; heat shrinkable cable accessories ground wire is used for welding.

4, contraction of the way the difference: shrink cable accessories selected core plastic support natural shrinkage; heat shrinkable cable accessories for fire heat shrinkage.

5, electric field control of difference: cold shrink cable accessories using geometric should stress cone to control the electric field; heat shrinkable cable accessories using heat shrinkable stress control tube to control the electric field. and there are some other differences, such as shrinkage cable accessories partial discharge quantity is small, the construction space is relatively small, slightly faster installation; heat shrinkable cable accessories in the partial discharge is larger, the construction space requirements, the installation of slower. Therefore, installation of heat shrinkable cable accessories technical requirements to be higher than the cold shrinking installation, shrinkage annex installed faster and more convenient.
