GW13-126 Outdoor disconnector of neutral point 126kv
GW13-126 isolation switch has a wide range of applications, especially for 110kv neutral ground system, which can effectively realize the isolation and switching of the circuit to ensure the safety of maintenance and fault handling. In addition, it can also be used with other power equipment such as lightning arrester, fuse, etc., to form a complete power system protection scheme .
The GW13-126 isolation switch is composed of a support, a base, a post insulator, a contact and a patch board. The post insulator and the conductive part are installed on the base, and the intersection Angle of the two post insulators is 50°. The base is fixed on a bracket with a tilt of 25°, which is equipped with a shaft connected with the operating mechanism, and can be equipped with a manual operating mechanism such as CS17G or CJ6
