  • Myth About SF6 Gas In Electrical Equipment

    Nov 10, 2014Basically 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. Low pressure and small size result in little gas quantities of only some kg.
