Sustainable Alternatives to sf6 gas 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 sf6 gas 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, sf6 gas is also an extremely potent greenhouse gas with
