    But more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earths atmosphere. According to the Intergovernmental Panel on Climate Change IPCC, abandoning SF 6 completely could contribute 1.5 percent to

  • Green Switching: A sustainable alternative for SF6 gas

    Aug 23, 2010SF6 is on the list of greenhouse gases in the Kyoto Protocol (1). SF6 is the most potent of the six main greenhouse gases, with a GWP of 23,000 (5). The United Nations institution that monitors this, the Intergovernmental Panel on Climate Change (IPCC), has since added SF6 gas to the list of extremely harmful greenhouse gases.

  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), is an extremely potent and persistent man-made and naturally occuring 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.

  • Sulfur hexafluoride circuit breaker - Wikipedia

    Sulfur hexafluoride circuit breakers protect electrical power stations and distribution systems by interrupting electric currents, when tripped by a protective relay. Instead of oil, air, or a vacuum, a sulfur hexafluoride circuit breaker uses sulfur hexafluoride (SF 6) gas to cool and quench the arc on opening a circuit. Advantages over other media include lower operating noise and no emission of hot gases,

    Sep 03, 2018Sulphur hexafluoride (SF6) is a man-made gas comprising of one sulphur and six fluoride atoms. SF6 gas is extremely chemically stable, non-flammable and highly electronegative, with an excellent dielectric property of approximately 2.5 times more than air. Therefore, it is commonly used in electrical switchgear, transformers and substations as an electrical insulation, arc quenching and
