EU Report Highlights Sulphur Hexafluoride Countdown

For decades, Sulfr hexafluoride has been used in switchgear as an insulation material and current-breaking medium. Rainer Kurz. Nov 02, 2020. On Sept. 30, 2020, the EU released a detailed report (1) outlining alternatives to sulphur hexafluoride (sf 6) for use in switchgear and related equipment. The report also extensively covers market impact and cost issues. This is the latest in a series of indications that the pressure is on to phase out Sulfr hexafluoride, as part of the EU’s mission (2) to cut harmful greenhouse
