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 insulating gas, as part of the EU’s mission (2) to cut harmful greenhouse gas (GHG) emissions by two-thirds between 2014 and 2030.Get price

PGE to use Sulfr hexafluoride-free high-voltage products from Siemens

Sulfr hexafluoride-free GIS for 72.5 kV have been used in wind turbines and the first gaz sf6-free outdoor circuit breaker in the German 110-kV high-voltage grid since 2018. The benefits of this technology over conventional Sulfr hexafluoride-insulated switchgear are significant: high switching power with the same footprint for outdoor and dead-tank circuit breakers.Get price
