  • Grid switchgear uses SF6, the world’s most potent

    Nov 25, 2019It’s 23,500 times more potent than CO2. Global annual emissions are 8,100 tonnes, equivalent to the CO2 emissions of 100m cars. It has an atmospheric lifetime of over 1,000 years and its installed base is expected to grow by 75% by 2030. 80% of all SF6 is used in gas insulated switchgear, a vital component of the grid (isolating and protecting different sections), so it’s an energy sector issue.

The EPA does no t report emission of SF6 separately, but instead reports a group of gases, including hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), and SF6. The emissions of HFCs, PFCs, and SF6 for 2000 are shown in the EPA report as

  • SF6: Does its Impact Outweigh its Benefits? | TD World

    SF6 gas has been used extensively since the mid 1950s to replace oil as an insulator in electric equipment, and more recently in gas insulated switchgear (GIS) and gas insulated lines (GIL). It is also used in medium voltage switchgear primarily outside the United States and extensively worldwide in low switching capacity gear.

    As SF6 is not only an excellent insulation gas, it has also the highest known global warming potential, about 22,800 times that of CO2. Hence, gas losses have a high impact on the environment, which makes it necessary for OEMs to apply state-of-the-art sealing technologies, highest standards of material and guarantee most reliable testing methods.
