What are the alternatives to sf6 gas gas?

Mar 31, 2020 · Director of Communications and CSR, ECA. Sulphur hexafluoride (sf 6) gas is an excellent electrical insulator. It’s great at preventing short circuits in medium- and high-voltage electrical installations that would otherwise lead to damage, disruption, fire or explosion. Unfortunately, SF 6 is also believed to be the world’s most potent greenhouse gas, with a global warming potential 23,500 times more, kg for kg, than CO 2 .

Development Sf6 Alternative Gases in Switchgears - Switchgear

Nov 23, 2019 · An additional alternative approach is proposed to use air for insulation. The possible candidates are introduced, which are air, N2, CO2, perfluorocarbon (PFC), hydrofluorocarbon (HFC), gas mixtures containing sf6 gas as shown in Figure 1 by boiling temperature. These gases do not have higher dielectric strength but lower GWP than sf 6, and their boiling points are below 0 ˚C.
