Alternatives for sf6 gas | 2020 | Siemens Energy Global

A hurdle to these solutions, though, are currently higher production costs compared to SF 6. This is why it is mainly energy suppliers in rich countries such as Norway or Germany who choose this more environmentally friendly technology. However over time cost should become lower thanks to economies of scale.

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 Sulfr hexafluoride 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, gaz sf6 is also an extremely potent greenhouse gas with
