GW1 outdoor AC high voltage isolating switch is suitable for installation on the line of outdoor high voltage power distribution equipment, which is used to cut off the line and convert the line when the line has voltage and no load. This product is a three-phase electrical appliance consisting of three separate single-pole isolating switches. Each single-pole isolating switch has the same components, such as base pillar insulator, front and rear static contacts, knife and arc angle, etc.
The isolating switch is composed of three identical single-pole isolating switches. When installing, the three poles are formed as a whole by the pipe connecting rod, and the CS8-1 manual operating mechanism is used. Each single-pole isolating switch has a separate iron frame, and two post insulators are installed at both ends, which are equipped with contacts. There is a rotating shaft in the middle of the iron frame, and the knife switch is opened and closed by means of a pull rod insulator. The GW1 switch is a double-column outdoor high-voltage isolation switch composed of three single poles. The switch is a one-way opening type. It consists of a base, an insulator, a contact knife guide and a conductive part. On both sides of the base, there are tie-rod insulators, a crank arm and a rotating shaft in the middle to open or close the switch. The switch can be equipped with an anti-theft operating mechanism or a common operating mechanism.
