SF6 however is not photo-decomposed at ozone layer altitudes (32-44 km), so very little atomic fluorine is released. Any free fluorine which is released has a strong tendency to combine with free hydrogen rather than with ozone.

  • Myth About SF6 Gas In Electrical Equipment

    May 25, 2020 · 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. Low pressure and small size result in little gas quantities of only some kg.
