Insulated bearer for breaker

The utility model discloses an insulated bearer for a breaker. The insulated bearer comprises a body and connecting pieces arranged inside of the body. The body consists of a cylinder body and an umbrella skirt which is arranged on the outer periphery of the cylinder body, distributed at intervals along the axial direction of the cylinder body, and capable of increasing the creepage distance. The connecting pieces are arranged on the end surfaces at the two ends of the cylinder body. On the basis of guaranteeing the insulation strength and mechanical strength of the body and on the premise of maintaining the size of a conventional insulated bearer, the umbrella skirt is capable of increasing the creepage distance of the insulated bearer, thereby decreasing the risk of surface breakdown of the insulated bearer in a high-voltage, narrow, and enclosed space.
