breakdown voltage of SF6/CF4 mixtures as add CF4 gas to SF6 gas (0.1MPa). All SF6/CF4 mixtures which have SF6 gas of 0.01MPa satisfied the standard of 25.8kV GIS in power frequency withstand voltage test. Mixed gas of SF6 (0.01MPa) and CF4 (0.01~0.06MPa) show more good dielectric characteristics than pure CF4 gasGet Price
