In view of the many shortcomings of the cross-linked cable itself and the partial discharge or electric tree discharge of the cable terminal due to the lack of attention to details by the construction personnel in the production of cold shrinkable accessories, we should strictly control the process in the future production process, and put forward the following preventive countermeasures and precautions
In the actual operation of power cable, there are quite a lot of accidents caused by COLD SHRINKABLE ACCESSORIES. Generally, the most likely place for cold shrinkable accessories to fail is in and near the middle connector and terminal head of the cable, especially the manufacturing process of the middle connector is more complicated, so it is relatively more likely to have potential accidents.
Heat Shrinkable Tube adopts high quality polymer, by scientific ratio, mechanical blending polymer, the product is formed by electron accelerator radiation crosslinking, continuous expansion.
For example, the product 10kV Cold Shrinkable Three Cores Termination Kit for Outdoor. Cold shrinkable cable accessories made of imported silicone rubber, it is with very good electrical performance, and also with excellent hydrophobicity, high elasticity, long usage life and constant pressure of shrinking.
The Cold Shrinkable Cable Accessories produced by Huayi cable accessories Co., Ltd. are all bonded with special sealing adhesive to realize the overall sealing and avoid operation accidents caused by atmospheric environment.
Heat shrinkable cable accessories (Heat Shrinkable Series) is a kind of power cable accessory, which is widely used in developing countries. It can be used in the cable joint and termination of crosslinked cable or oil-immersed cable of 35KV and below voltage grade, so there are Heat Shrinkable Straight Through Joint and Heat Shrinkable Termination Kit.
