Sulfr hexafluoride Decomposition in Gas-Insulated Equipment - IEEE Journals

Abstract: The increasing application of sf6 gas as an insulating gas has led to many studies on sf6 gas decomposition in gas-insulated equipment. In the presence-of an electric arc, spark or corona, insulating gas decomposes to a wide variety of chemically active products which possess completely different properties from gaz sf6.

gaz sf6 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. sf6 gas 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.

Sulfur hexafluoride - Wikipedia

Sulfur hexafluoride or sulphur hexafluoride, is an extremely potent and persistent greenhouse gas that is primarily utilized as an electrical insulator and arc suppressant. It is inorganic, colorless, odorless, non-flammable, and non-toxic. SF 6 has an octahedral geometry, consisting of six fluorine atoms attached to a central sulfur atom. It is a hypervalent molecule. Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of
