Advancements in Clean Air Insulation Technologies for Switchgear and Circuit Breakers

Our power systems and grids are rapidly transforming to help realize a CO2 -neutral world. Reducing CO2 and equivalent greenhouse gases (GHG) is an important step to address global warming. Power systems must phase out the most potent GHG, sulfur hexafluoride (SF6 ), to achieve this CO2 -neutral society. SF6 has the highest known global warming potential (GWP) of all GHG, estimated to remain in the atmospheric environment for 3,200 years. There is also no SF6 gas waste management system commercially available today. At the same time, utilities must ensure transmission performance and reliability are maintained or increased.
