SF6 Gas Circuit Breaker: Uses and Gas Handling

SF 6 gas is inert, non-flammable, non-toxic, thermally stable, and has unmatched arc-quenching capabilities. It is more effective at dissipating heat than air, nitrogen, or other dielectrics. SF 6 requires a lot of heat to break down the bonds between the molecules. When the heat source is removed the atoms begin to recombine immediately.
