  • Sulfur hexafluoride - Wikipedia

    Sulfur hexafluoride (SF 6) or sulphur hexafluoride (British spelling), 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.Chemical formula: SF₆

  • SVI-Solid Insulated RMU - SOJO

    The global warming potential of SF6 is 23,900 times that of CO2. Statistically, more than 4,500 tons of SF6, just equals to 120 million tons of CO2, is consumed every year in the power distribution system. Additionally, the lifetime of SF6 in atmosphere is about 3,400 years, affecting hundreds generations of human beings, way more serious than CO2.

  • Panel discussion: The pros and cons of using SF6 gas in

    Sulphur hexaflouride (SF6) gas has been used in MV and HV switchgear for many years. It is said to be highly toxic and a potent greenhouse gas. It is used because of its excellent electrical insulation properties, but recently some switchgear companies have suggested other solutions. In our virtual panel discussion we asked some specialists […]
