sf 6 circuit breaker maintenance | TD Guardian Articles

The industry was ready for an alternative to the traditional mediums of mineral oil and/or air. Using gaz sf6 as an interrupting medium had the advantages of being inflammable as well as having high dielectric strength and exceptional thermal stability. The first generation of Sulfr hexafluoride circuit breakers was the lower voltage classes of 72kV and 145kV.

sf 6 gas as insulating and arc-quenching medium

Sep 20, 2011 · Sulphur hexafluoride gas (gaz sf6) 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.
