Get PriceNov 01, 2018SF 6 gas is widely used in electric power apparatus as an insulation and arc-quenching medium. However, the application of SF 6 gas faces two serious problems, including the heavy global warming effect and high toxicity of its decomposition products. So, scholars committed to finding environmental-friendly alternative to SF 6 gas and the relevant research results have been obtained.
Get PriceIn gas insulated transformer, gas is used as the insulating and cooling medium for the transformer. Sulphur Hexafluoride, SF6 is the gas used in gas insulated transformer. These transformers are adopted due to its environment-friendliness, non-explosive and non-flammable in nature.
