High-voltage heat shrinkable cable accessories can be divided into 10kv and 35kv ones. 10kv are suitable for 8.7/15kv cable termination processors, and 35kv are suitable for 26/35kv cable termination processors.

Let us introduce materials of high-voltage heat shrinkable cable accessories first. In fact, it is not only heat shrinkable cable accessories, as long as other heat shrinkable products, such as heat shrink tube of different pressure levels, insulation protection boxes, middle wall tubes, double wall tubes etc. Both of them are made of PE, EVA and other materials, which through a series of processing techniques. To put it simply, the production process is to pelletize the formulated raw materials, and then form by extrusion, and pull them to the irradiation factory for irradiation, and wait until the irradiated products are returned to the factory before they are processed, and expansion, the final step is packaging.

The above is the production process of heat shrinkable cable accessories, because of the particularity of its production process, high pressure heat shrinkable cable accessories have the characteristics of being heated to shrink and be tightly wrapped on the covered object. Heating tools are needed during the operation. Once heating tools are used for operation, the construction personnel must be particularly cautious. Because in the process of operation, it is likely to cause damage and rupture to the product. Most feedback on the rupture and damage of heat shrinkable products are for improper operation methods. Therefore, the operation method should be cautious.
