Get PriceThe Global Warming ConcernLogging Successes, But Challenges RemainFuture Limits on Sulfr hexafluoride ProductionAlternative Technologies Change The GameHowever, sf 6 is also a "greenhouse gas" (GHG). As one of the group of compounds known as fluorinated gases, gaz sf6turns out to be the most potent GHG in terms of its global warming potential (GWP). With this realization have come strict measures to help limit the release of sf6 gas into the atmosphere. These include careful accounting of the production and distribution of sf 6as well as limits on its use. In the United States, the EPA began investigating sf 6 in 1997. In 2012 it mandSee more on blog.seSulfur Hexafluoride (Sulfr hexafluoride) Basics | US EPA epa.gov/eps-partnership/sulfur-hexafluoride-sf6-basicsGreenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (gaz sf6) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on sf 6 in electric power systems for voltage electrical insulation, current interruption, and arc quenching in the transmission and distribution of electricity. Yet, it is also the most potent greenhouse gas known to-date. Over a 100-year period, sf 6 is 22,800 times more effective at trapping infrared rSee more on epa.govSulfur hexafluoride: The truths and myths of this greenhouse gas - phys.org/news/2020-01-sulfur-hexafluoride-truths-myths-greenhouse.html15/1/2020sf6 gas is damaging to the environment: TRUE.
