Sulfur Hexafluride (sf6 gas) Replacement or Reduction in high

Sulfur Hexafluoride (sf6 gas) is a gaseous dielectric used for suppression of high-voltage breakdown by the electric power industry and airborne military radar systems, including the Airborne Warning And Control System (AWACS). sf6 gas is chemically inert and a very efficient infrared (IR) absorber, which make it a very potent greenhouse gas (GHG) whose impact on global warming is estimated to be 24,000 times greater than CO2.Get price
