Gas Insulated Switchgear

The SRM16-40.5 Gas Insulated Switchgear (GIS) is a medium voltage (40.5kV) rated gas insulated switchgear. It uses SF6 and other insulating gas as the main insulating medium, the main components such as bus, circuit breaker, isolating switch, transformer, arrester and so on are closed in the grounded metal shell, and through the optimized design of the electrical connection and insulation structure, the circuit in the power system can be switched on, protected and controlled.
