Medium-voltage switchgear - ScienceDirect· GIS switchgear Gas-Insulated switchgear (GIS) also uses SFe gas to insulate not only the switch contacts, but most of the switchgear panel, including the busbars. The GIS has been used at the higher-voltage levels, namely 66 kV and above, but is also becoming a viable option for medium-voltage applications in special circumstances.[email protected]
