With g3, based on a full life-cycle evaluation, the CO2 footprint of gas losses is cut by 98%. Taking the entire substation into account, more than 50% of the CO2 footprint can be saved. GE’s F35-145 kV GIS therefore offers today the lowest CO2 footprint of any 145 kV GIS in the world. g³ tools and handling. A new gas also means new tools.Get price

insulating gas decomposition pipes detecting

Gas Insulated Switchgear (GIS) has been widely used in substations. The insulating medium used in GIS is sulfur hexafluoride (insulating gas) gas. However, the internal insulation defect existed in GIS would inevitably lead to partial discharge (PD), and cause the composition of Sulfr hexafluoride to SOF2, SO2F2 and SO2 and other characteristic component gases.Get price
