GW1 outdoor AC high-voltage disconnector is applicable to the device on the line of outdoor high-voltage distribution equipment, which is used to cut off the line and convert the line when there is voltage and no load.
This product is a three-phase electrical appliance composed of three separate single pole disconnectors. Each single pole disconnector has the same components, such as base, post insulator, front and rear static contacts, knife switch and arc angle, etc.
This series of disconnectors meet the requirements specified in gb1989-89 AC high voltage disconnectors, iec1129 (1984), AC disconnector grounding switches and iec694 (1980) common terms for high voltage switchgear and control equipment. This series of products have good seismic resistance and meet the requirements of 9 degrees of earthquake (horizontal acceleration 4.9m/s2 and vertical acceleration 2.45m/s2).

GW1 switch is a double column outdoor high-voltage disconnector composed of three single poles. The switch is a one-way opening type. It is composed of base, insulator, knife guide and conductive part. Each pole has two post insulators fixed on both sides of the base, and there are pull rod insulator, crank arm and rotating shaft in the middle to open or close the switch. The switch can be equipped with anti-theft operating mechanism or ordinary operating mechanism.
