Gas Insulated Switchgear - GIS

ABB pioneered high-voltage gas-insulated switchgears in the mid-1960s. It continues to drive innovation today with a product portfolio that includes voltage levels from 72.5 kV to 1,100 kV.

Main features of ABB GIS, like extremely low space requirements and high reliablility, offer smart and economic solutions for complex switchgear applications, e.g. in densely populated areas, for aesthetic town planning or under severe environmental impact.
