  • Panel discussion: The pros and cons of using SF6

    10 mins readJul 14, 2015SF 6 is always used in gas tight compartments, which greatly minimise leaks. As the quantities that leak from the switchgear are low, the contribution to the greenhouse effect can be considered extremely minimal to affect climate changes.

    Gas-insulated switchgears are furthermore never absolutely leakproof. Leaks in seals, flanges, etc. allows SF 6 to emerge and allows air to enter. The loss rate of sulphur hexafluoride is generally about 0.5 percent by volume of SF 6 per year. These leaks must be eliminated immediately, since sulphur hexafluoride is extremely harmful to the environment.

    8 mins readNov 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.
