Electromagnetic insulator of transformer substation

The utility model relates to the field of insulators, in particular to an electromagnetic insulator for a transformer substation, and aims to solve the technical problems that the surface of an insulator is cleaned by special equipment in the prior art, however, omission is often caused by manual operation, and the special equipment is very inconvenient to transport. The connecting gold pieces at the two ends are rotationally connected to the bearing frame and the fixing frame respectively, the bearing frame and the fixing frame are connected with different conductors, the fixing frame is fixedly arranged, a sliding groove is formed in the fixing frame, the brush rod is connected into the sliding groove in a sliding mode, bristles are connected to the brush rod, the bristles are located between the two insulators, and the brush rod slides through the transmission mechanism. The connecting metal piece rotates through the transmission mechanism, the cleaning assembly and the insulator are integrally arranged, c
