  • 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.

    Tracer gas leak testing is a simple and highly-efficient method of leak detection that provides high sensitivity, accuracy, and repeatability. A tracer gas leak test can be used to test parts with very low leak rates that are outside the range for conventional air-flow pressure decay and mass flow testing, or to replace bubble test methods.
