Product technical advantages and features

·The stress cone is formed by injection molding with high-quality imported liquid silicone rubber, and the finite element electric field analysis is used for optimized design, which solves the problem of electric field optimization of the product to ensure the reliability of long-term operation of the product.

·The terminal adopts a multiple sealing structure, which can be disassembled at any time to solve the problems of water ingress and oil leakage in the terminal, making operation and maintenance more convenient.

·The composite bushing uses a silicone rubber umbrella skirt as external insulation, which has excellent anti-pollution flashover, anti-ultraviolet, and anti-aging properties.

·The product is light in weight, convenient to transport and install, and has good explosion-proof performance.
