  • SF6-free Innovative technology for - Schneider

    Air has no global warming potential (GWP), no sole-source supply, and is sustainable by nature. Air-based technology is reliable and future-ready, free from regulatory considerations. To enable the change from SF6, Schneider Electric has combined air for insulation and vacuum technology for arc interruption.
