Nov 02, 2020. On Sept. 30, 2020, the EU released a detailed report (1) outlining alternatives to sulphur hexafluoride (gaz sf6) 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 sf 6, as part of the EU’s mission (2) to cut harmful greenhouse gas (GHG) emissions by two-thirds between 2014 and 2030.Get price
