  • 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

    The default equipment leak rate for SF6 equipment is 0.5% per annum for closed pressure systems and 0.1% for sealed pressure systems. If any SF 6 filled chamber is being topped up every 6 years or less due to low SF6 gas pressure, then an investigation will be conducted to find the source of leakage. When a leak occurs, SF 6

    The process is reversible, so that nearly all of the SF6 recombines after interruption. Thus, very little of the SF6 is "used up" during interruption, particularly for interruption of moderate (load) currents. SF6 dissociates during arcing into its atomic constituents, one sulfur atom and six fluorine atoms.
