Gas-Insulated Switchgear (DC-GIS) | Gas-insulated ... gas-insulated switchgear from Siemens (DC-GIS) saves space, time & money. Based on the proven switchgear-technology it enables in numerous of applications in the high-voltage-direct-current transmission a voltage up to ±500 kV and stands out with an excellence weather resistancy.
Switchgear - Wikipedia for lower voltages may be entirely enclosed within a building. For higher voltages (over about 66 kV), switchgear is typically mounted outdoors and insulated by air, although this requires a large amount of space. Gas-insulated switchgear saves space compared with air-insulated equipment, although the equipment cost is higher.
