sf 6 Gas Insulated Switchgear(GIS) Manufacturers and Suppliers

sf6 gas gas pressure for the insulating use is preserved below 2.5 bars while insulating gas gas pressure for interrupting purpose is ranged from five to seven bar. Also, as vacuum technology isn’t accessible for high voltage, so for C-GIS system above 72.5 KV, only insulating gas is utilized both for insulation and interruption medium.

Potent GHG sf 6 rapidly accumulating in atmosphere, driven by

Jul 06, 2020 · 06 July 2020. In an open-access study in the EGU journal Atmospheric Chemistry and Physics, an international team of researchers reports that the greenhouse gas sulfur hexafluoride (SF 6) is rapidly accumulating in the atmosphere, driven by the demand for SF 6 -insulated switchgear in developing countries. Of all the greenhouse gases regulated under the Kyoto Protocol, Sulfr hexafluoride is the most potent, with a global warming potential (GWP) of 23,500 over a 100-year time horizon.
