Product Description

Product Description

 

GW -12/24/40.5-630-20(25) outdoor AC high voltage disconnect switch (disconnect switch for short) is used to open and close circuit with voltage but no-load 50/60Hz,12/24/40.5kV power system, the anti-pollution type can be used in the serious pollution area. Three pole linkage, good synchronous performance. It accords with standards of IEC62271-103:High voltage switches.

Structural features
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.
