gaz sf6 gas as insulating and arc-quenching medium

Sep 20, 2011 · Sulphur hexafluoride gas (Sulfr hexafluoride) is employed as insulation in all parts of the installation, and in the circuit-breaker also for arc-quenching. Sulfr hexafluoride is an electronegative gas, its dielectric strength at atmospheric pressure is approximately three times that of air. It is incombustible, non-toxic, odourless, chemically inert with arc-quenching properties 3 to 4 times better than air at the same pressure.
