Prefabricated cable accessories are made by injection molding and vulcanizing high-temperature vulcanized silicone rubber, and processed into tubular components of various structures (without expansion).

        On-site installation, the tubular parts smaller than the cable insulation diameter molded by vulcanization are directly placed on the cable insulation at the end of the treated cable or at the joint. Since the inner diameter of the silicone rubber part is smaller than the cable insulation, it can be directly pressed against the cable. Insulate the surface to form a prefabricated cable accessory.

     It can also be said that, due to the continuous introduction of new varieties of silicone rubber materials, the gradual improvement of physical properties of silicone rubber materials, and the advancement of processing technology of silicone rubber, especially liquid high-temperature vulcanized silicone rubber materials, new products are developed for the power cable accessories industry , To improve product quality and improve product qualification rate created conditions.
