Introduction. SF6 is a colorless non-toxic gas, with good thermal conductivity and density approximately five times that of air (6.14 kg/m 3.).It does not react with materials commonly used in high voltage circuit breakers.Applications for SF6 include gas insulated transmission lines and gas insulated power distribution
