  • SF6-free Innovative technology for - Schneider Electric

    for your network For decades, SF6 (sulfur hexafluoride) has been trusted for use in MV switchgear, but it is the most potent greenhouse gas. The time has come to move away from SF and switch to the best sustainable gas: pure air. It helps improve safety and avoid future regulatory risks as well as recycling treatment and costs.

    Of all the greenhouse gases regulated under the Kyoto Protocol (United Nations, 1998), SF 6 is the most potent, with a global warming potential (GWP) of 23 500 over a 100-year time horizon (Myhre et al., 2013). In practical terms, this high GWP means that 1 t of SF 6 released to the atmosphere is equivalent to the release of 23 500 t of carbon dioxide (CO 2).
