Product Description

Liugao is a 132KV Outdoor High Voltage Disconnecting Switch supplier. The GW4 Outdoor Disconnecting Switch is composed of a base, an insulating strut, a conductive part, and an operating mechanism. Each pole is equipped with two pillars, and the upper end of each pillar is fitted with a conductive knife. The contacts of the knife are positioned in the middle of the two pillars. At the lower ends of the pillars, bearing sleeves are installed. Driven by the operating mechanism, the knife can be horizontally rotated by 90° to fulfill the requirements of opening and closing. The outdoor disconnecting switch is designed for use in three-phase AC 50Hz electrical systems to switch on/off the high-voltage circuit when there is no load in the circuit, allowing charging or transferring of the circuit. It is also used to disconnect the current with the bus bar, breaker, or any other high-voltage electrical equipment during circuit maintenance.
