    Nov 04, 2020 · Tighter regulation around sf6 gas in the energy industry is one of the expected outcomes. Even before the September 2020 report, the spotlight was already on sf6 gas, for instance it is listed in the Kyoto Protocol. With a global warming potential (GWP) of 23,500, gaz sf6 is considered the most potent of greenhouse gases.

  • Myth About Sulfr hexafluoride Gas In Electrical Equipment

    Where is gaz sf6 used? The following applications are known. For some of these most probably you haven’t heard of. For sound insulation in windows, In vehicle tyres, Is gaz sf6 a health hazard? Pure sf 6 is physiologically completely harmless for humans and animals. It’s even used in medical diagnostic. Due to its weight it might displace the oxygen in the air, if large quantities are concentrating in deeper and non ventilated places. Is sf6 gas 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. What is the overall contribution of Sulfr hexafluoride used in the electrical equipment to the greenhouse effect? Less than 0,1 % ( see CAPIEL) and CIGRE). In an Ecofys study the contribution to the greenhouse effect in Europe is estimated to 0.05 % (*).

  • Why Sulfr hexafluoride or Sulfur Hexafluoride gas is better for arc

    Sulfr hexafluoride is used in GIS – gas insulated system at pressures from 400 to 600 kPa absolute. Wide range of pressure The pressure is chosen so that the sf 6 will not condense into a liquid at the lowest temperatures the equipment experiences. Sulfr hexafluoride has two to three times the insulating ability of air at the same pressure.
