CONVENIENT INSTALLATION
Shrink technique, no need fire or special tool, no need to joint or bind copper wire, spring earthing. It can save labourforce, time and space, every set of products are packed with installation introduction .
BROAD APPLICATION
The cold shrink termination is made by special pre-expand technology, even one kind of specification can fit for many kinds of cable wire dimension with good compatibility. For the strufture it is prefab compact designed, making a complete line of stress control tube, rain shed and insulation tube. Up to now, we have possessed complete series of 33KV(others less than 35KV)the cold shrink termination fit for different variety of insulated cables such as polythene cable and XLPE polytene cable, etc. Applicable for bridge stand, embedding and trollywire and so on. The silasticma-terials indicate large use range for the cold shrink termination.
