    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.

    Apr 24, 2018 · As discussed, in 220 kV, 400 kV and 765 kV applications, the SF6 gas pressure is maintained at 6.5 bar. You will be amazed that, even though voltage level is increasing, same pressure of SF6 i.e. 6.5 bar is used for 220, 400 and 765 kV applications. Actually as we go up at higher voltage level, the number of contacts increases in SF6 circuit
