Compact High Voltage Direct Current (HVDC) Transmission ...· PDF file2.2 Gas-Insulated Systems. The increasing demand for HVDC technology requires the adaptation of gas insulated switchgear (GIS) or lines (GIL), which were originally developed for the AC grid. GIS are particularly relevant for applications where building volume or right-of-way are critical issues, e.g. for mega-city in-feed or
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.
