    Breakdown voltages of SF6/N2 and SF6/C02 (50/50) gas mixtures at low pd-values. Symbols: 0, d = 0.04 mm, x, d = 0.65 SF6/N2; A, d = 0.04 mm, U, d = 0.65 mm, SF6/C02. minimum of the SF6/Nz mixture is about the same as that of COz. Therefore it seems that the gas mixture, though very promising for compressed gasCited by: 14
