    The key difference between g3 and SF6 is that g3 is a gas mixture while SF6 is a single gas. Elodie Laruelle, GE Grid Solutions Eco-design Engineer, explains: “ The critical point for a gas mixture is to maintain the homogeneity of the two components (NovecTM and CO2) throughout the filling process.

  • Development Sf6 Alternative Gases in Switchgears - Switchgear

    Nov 23, 2019 · The possible candidates are introduced, which are air, N2, CO2, perfluorocarbon (PFC), hydrofluorocarbon (HFC), gas mixtures containing SF6 as shown in Figure 1 by boiling temperature. These gases do not have higher dielectric strength but lower GWP than SF6, and their boiling points are below 0 ˚C. Other approaches to apply new alternative gases with low GWP to gas-insulated systems are now under study.
