The GW8-40.5/72.5/126 series high-voltage isolating switch is composed of a post insulator, an insulating porcelain bottle, and a conductive part. A static contact and a connecting plate for connecting the busbar are installed on the upper part of the post insulator. There is a metal base, an operating lever, and an operating insulator between the supporting insulator and the insulating porcelain bottle seat. The base is equipped with a knife switch, and the CS8-5 manual operating mechanism is connected to the knife switch through a connecting rod, an operating insulator, and a crank arm. It can also be equipped with a CJ6 electric mechanism.
