Alternatives for Sulfr hexafluoride | 2020 | Siemens Energy Global

But more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earthatmosphere.

Sustainable Alternatives to gaz sf6 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 gaz sf6 gas as an insulating and/or interrupting medium within MV and HV equipment. Sulfur Hexafluoride (insulating gas) gas is largely used as a dielectric and insulating material in the transmission and distribution equipment. Unfortunately, gaz sf6 is also an extremely potent greenhouse gas with
