sf6 insulated switchgear leakage IEC specifications

sf6 insulated switchgear leakage IEC specifications

The term GIS (gas insulated switchgear) in MV is commonly used also in hybrid solutions, which are partially SF6 based switchgear systems. It is used where, for example, the busbars are solid dielectric and only the circuit breaker, disconnectors and earthing switch are in sf6 gas. GIS is today a proven technology with more than 30 years of ...
