Bushing Cover For Transformer, in other words, A transformer insulation protective sleeve belongs to the field of power equipment. Its main body is a set body. The sleeve body is a hollow rectangular structure. One end of the sleeve body is connected with an outlet, and the top of the other end is provided with a cylindrical wiring port, wiring port, and sleeve The outlet is provided with an opening edge, and the opening edge is provided with a buckle, characterized in that: the outlet is provided with an annular clamp ring, the top of the clamp ring is extended with a convex edge, and the convex edge is provided with a buckle on the edge Corresponding to the card hole, the sleeve body is made of synthetic silicone rubber. The utility model has simple structure and reasonable design, the synthetic silicone rubber material will never be deformed, and the flexibility and tearability are high; the installation is convenient, and the buckle structure is convenient for maintenance. Disassembly and re-use; the setting of the clamp ring can effectively stabilize the cable and prevent friction and loosening.
