  • SF6-free Innovative technology for greater sustainability and

    A breath of fresh air 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.
