Sulfur Hexafluoride (SF6) is an inorganic, colorless, odorless, and non-flammable gas. The primary use of Sulfur Hexafluoride (SF6) is as a gaseous dielectric medium in the electrical industry for various voltage circuit breakers, switchgear and other electrical equipment; this often replaces oil filled circuit breakers (OCBs) that can contain harmful PCBs.

Oct 15, 2009· In this study, we investigated the pure SF6 and SF6-N2 mixture gas hydrates formation equilibrium aswell asthe gas separation efficiency in the hydrate process. The equilibrium pressure of SF6-N2 mixture gas was higher than that of pure SF6 gas. Phase equilibrium data of SF6-N2 mixture gas was similar to SF6 rather than N2.
gas to SF6. CHARACTERISTICS OF GAS CANDIDATES The pure gas and gas mixtures must offer following features: non toxic, non corrosive, non flammable nor explosive, low GW, and no or very low ODP (Ozone Depletion Potential). Overall it must be environmental friendly. Among the wide range of available gases, those from the
1 COLD-WEATHER APPLIION OF GAS MIXTURE (SF 6/N 2, SF 6/CF 4) CIRCUIT BREAKERS: A UTILITY USER’S PERSPECTIVE R. L. Middleton, P. Eng. Manitoba Hydro, Winnipeg, Canada SUMMARY Very low temperatures stress a circuit breaker in a complex manner.
Sulfur hexafluoride (SF 6) is an inorganic, colorless, odorless, non-flammable, non-toxic extremely potent greenhouse gas, and an excellent electrical insulator. 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, it is poorly soluble in water but quite soluble in nonpolar organic solvents.
