Product Overview

    GW22-126, 252-type disconnecting switches are three- pole outdoor high-voltage electrical appliances for 126kV/ 252kV, 50Hz high-voltage lines to switch lines under no current-carrying conditions, and to electrically isolate the electrical equipment under repair from live lines. The moving contact system of this product is a manipulator type single arm folding type. The transmission parts are sealed inside the conductive tube and are not affected by the external environment. The balance spring in the conductive tube is used to balance the gravitational moment of the moving element, making the opening and closing action very light and stable.

    The clamp structure is used to clamp the static contact conductive rod, and the clamping force is guaranteed by the clamping spring force in the conductive tube. The top pressure trip device is used to ensure the reliable closing of the disconnecting switch. The conductive tubes of the main knife and the ground knife are made of aluminum alloy, and the moving and static contacts are copper plated with silver. The rotating joint has a composite bushing with excellent wear resistance and conductive rolling contact fingers. The mechanical and electrical properties are very good. stable.
