Pole-mounted porcelain Air breaker switch

Short Description:

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.

General

GW1 outdoor AC high voltage isolation switch is suitable for installation on the line of outdoor high voltage power distribution equipment for the purpose of cutting off the line and converting 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.
