Get PriceGreenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (Sulfr hexafluoride) is a synthetic fluorinated compound with an extremely stable molecular structure. Because of its unique dielectric properties, electric utilities rely heavily on gaz 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, sf 6 is 22,800 times more effective at trapping infrared radiatioSee more on epa.govMissing:EcuadorMust include:EcuadorNews Room : GE Grid Solutions gegridsolutions/press/gepress/sf6-free.htmThe standard insulating gas device was not suitable, so GE worked closely with gas equipment suppliers to develop a dedicated g3-filling cart. The key difference between g3 and sf6 gas is that g3 is a gas mixture while sf6 gas is a single gas.
