Gas-Insulated Switchgear
The gas-insulated switchgear integrates high-voltage components including vacuum circuit breakers, three-position switches, busbars and inner cone cable sockets. Fully enclosed in a laser-welded stainless steel gas tank, it adopts mature sealing technology and sophisticated craftsmanship to operate independent of external environments, suitable for harsh working conditions such as humidity, high altitude and heavy pollution.
