Myth About SF6 Gas In Electrical Equipment· From 0kV thru 800kV SF6 is my choice for the insulating and arc-extinguishing characteristics delivered by SF6. it is heavier than air, and just as the old OCB's were designed, the SF6 chamber and contacts are designed much like they were, whereby a "puff" of SF6 gas is jettisoned right through the arc zone thus assuring the thorough ...
Myth About SF6 Gas In Electrical Equipment· 3. Is SF6 harmful for the environment? It has no ecotoxic potential, it does not deplete ozone. Due to its high global warming potential of 22.200 (*) it may contribute to the man made greenhouse-effect, if it is released into the atmosphere. However in electrical switchgear the SF6 gas is always used in gas-tight compartments, greatly minimising leakage.
