  • SF6 End-of-life evacuation

    SF6 End-of-life evacuation. May 25, 2020SF6-insulated switchgear makes a substantial contribution to reduce the accident risk. The total enclosure of all live parts in earthed metal enclosures provides immanent protection against electric shock and minimises the risks associated with human errors The high-grade switchgear remains hermetically sealed for its whole service life.
