    Nov 01, 2018SF6 is a non-combustible gas with good insulating properties and quenching arc performance. By 1938, Cooper from American suggested it as an insulating medium. In the same year, V. Grosse from German has proposed SF 6 as arc media of the high-voltage circuit breaker. SF6 gas was supplied commercially in 1947.
