Get PriceGreenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (sf 6) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on sf6 gas 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, Sulfr hexafluoride is 22,800 times more effective at trapping infrared radiatioSee more on epa.govSulfur hexafluoride circuit breaker: Types Working Principle mariaelectricals/sf6-circuit-breaker5/6/2020Types of sulfur hexafluoride circuit breaker.
