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 insulating gas as shown in Figure 1 by boiling temperature. These gases do not have higher dielectric strength but lower GWP than sf6 gas, and their boiling points are below 0 ˚C.
