Gas Insulated Switchgear (GIS)

The gas insulated switchgear, abbreviated as GIS, is a combination of circuit breaker, disconnecting switch, grounding switch, bus, mutual inductor, lightning arrester and other components. These electrical components are housed in enclosed metal containers which are filled with SF6 gas for insulation and arc extinguishing.

Featuring small footprint, safe and reliable operation, easy maintenance, and high weatherability, this metal enclosed switchgear is the best choice for various transformer substations.

Our company started producing GIS in 1983. Up to now, we have produced more than 8,000 bays and assembled about 900 substations. Our gas insulated switchgears have been exported to many countries in Africa, Eastern Europe, and Southeast Asia. By means of the rich experience in design and production, we have provided a variety of safe and reliable electric power system components to customers.

As a China-based gas insulated switchgear (GIS) manufacturer and supplier, we also offer withdrawable switchgear, low voltage switchgear, high voltage circuit breaker, high voltage vacuum contactor, and more.
