  • Myth About SF6 Gas In Electrical Equipment

    Nov 10, 2014What is the difference between high-voltage (HV) and medium- voltage (MV) GIS regarding SF6? Basically there is no difference as both applications use the SF6 in gas-tight compartments with negligible leakage rates. In general the MV (up to 52 kV) use pressures close to atmospheric pressure in sealed pressure systems.
