Safe and efficient sf6 insulation Russia

Greenhouse GasUse in Electric Power SystemsCommon Emission SourcesSulfur hexafluoride (sf6 gas) 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 kSee more on epa.govMissing:RussiaMust include:RussiaABB expands eco-efficient medium-voltage portfolio new.abb/news/detail/18522/abb-expands-eco-efficient-medium...1/4/2019ABB expands eco-efficient medium-voltage portfolio.
