Anqiang Power manufactures a reliable Indoor High Voltage Disconnect Switch designed for safe isolation and circuit separation in 12kV distribution systems. The GN19 series is widely applied in indoor switchgear rooms, substations, and industrial power control cabinets where visible disconnection and operational safety are required. Its three-pole structure ensures synchronized operation and stable mechanical performance under repeated switching conditions.
The device is built with a rigid base frame, rotating shaft mechanism, porcelain post insulators, and high-conductivity copper switch blades. Each component is engineered to maintain stable contact pressure and minimize electrical resistance during operation, ensuring long service life and dependable switching performance in medium-voltage networks.
The switch adopts a three-pole integrated mechanical structure consisting of a base frame, rotating shaft system, connecting rods, porcelain post insulators, and copper alloy switch blades. The operating shaft can be flexibly connected to manual or motorized operating mechanisms, allowing adaptable installation in different switchgear layouts.
Special variants such as GN19-12W, GN19-12G, GN19-12X, and GN19-12ST are designed for different environments including polluted areas, high-altitude regions, voltage indication requirements, and double-throw switching applications.
