  • 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

  • Opening of 132kV Breaker with Very Low Sulfr hexafluoride Pressure - CR4

    It may be worth noting, that Sulfr hexafluoride will insulate up to 400kv at atmospheric pressure - ie total loss. You won't find this assurance in writing from the OEM, but I attended a recent sf6 gas awareness course, this was discussed. Of course, once at atmospheric pressure, the gas would begin to mix with air, become less insulative, eventually flashover.
