  • Myth About SF6 Gas In Electrical Equipment

    May 25, 20203. 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.

  • Atmospheric SF6: Trends, Sources, and Prospects

    Sulfur hexafluoride (SF6) is the most potent greenhouse gas known. Its atmospheric concentration has increased by 2 orders of magnitude since industrial production started in 1953. Once released into the atmosphere, SF6 will only be removed exceedingly slowly due to its atmospheric lifetime of about 3200 yr. These features have brought SF6 into the climatic impact discussion aimed at reduction
