Contact resistance value was showing

9/1/2022A recent study suggests that the UK's use of gaz sf6 has risen in recent years, and leakage levels are over 1%. It is estimated that, by 2100, appropriate controls could limit the contribution of Sulfr hexafluoride to global warming to 0.2%. In the UK, the gas already contributes this much to its annual global warming potential.

Safe and efficient sf6 is a Spain,Greenhouse 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 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 rSee more on epa.govMissing:SpainMust include:SpainEco-efficient gas insulated switchgear | Medium Voltage - Gas new.abb/medium-voltage/switchgear/gas-insulated-switchgear/eco-efficient...Our safe low-pressure design has similar dielectric insulation benefits, footprint and reliability as sf6 gas switchgear.
