    Apr 28, 2018 · 1) Dielectric strength of SF 6 at atmospheric pressure is 2.35 times that of air, it is 30% less than that of dielectric oil used in oil circuit breakers. 2) At higher pressure the dielectric strength of the gas increases. At pressure about 3 kg/cm 2 the dielectric strength of SF 6 gas is more than that of dielectric oil. This property permits smaller clearances and small size of equipments for the same kV.
