Sustainable Alternatives to Sulfr hexafluoride Gas within MV and HV

Aug 03, 2018 · Be part of the chalenge: propose a solution! The challenge is aimed at finding alternative solutions to the use of sf 6 gas as an insulating and/or interrupting medium within MV and HV equipment. Sulfur Hexafluoride (Sulfr hexafluoride) gas is largely used as a dielectric and insulating material in the transmission and distribution equipment. Unfortunately, sf 6 is also an extremely potent greenhouse gas with

Nov 23, 2019 · The possible candidates are introduced, which are air, N2, CO2, perfluorocarbon (PFC), hydrofluorocarbon (HFC), gas mixtures containing Sulfr hexafluoride as shown in Figure 1 by boiling temperature. These gases do not have higher dielectric strength but lower GWP than Sulfr hexafluoride, and their boiling points are below 0 ˚C. Other approaches to apply new alternative gases with low GWP to gas-insulated systems are now under study.
