Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (SF6) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on SF6 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, SF6 is 22,800 times more effective at trapping infrared radiation than an equivalent amount of c…See more on epa.govPublished: 2021/2/4Sulfur Hexafluoride Market Insights, Trends Growth Outlook transparencymarketresearch/pressrelease/sulfur hexafluoride market.htm2019/3/27In terms of value, the global sulfur hexafluoride market is projected to expand at a CAGR of 6.3% from 2018 to 2026, according to a new research report titled 'Sulfur hexafluoride Market – Global Industry Analysis, Value, Share, Growth, Trends, and Forecast, 2018–2026' published by Transparency Market Research (TMR) .In terms of value, the global sulfur hexafluoride market is expected
