EU Report Highlights Sulphur Hexafluoride Countdown

Nov 02, 2020. On Sept. 30, 2020, the EU released a detailed report (1) outlining alternatives to sulphur hexafluoride (Sulfr hexafluoride) 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 gas (GHG) emissions by two-thirds between 2014 and 2030.

Sulfur hexafluoride circuit breaker - Wikipedia

Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases, and relatively low maintenance. Developed in the 1950s and onward, sf 6 circuit breakers are wid
