SF6 Gas Transformers | Transmission Distribution Systems ...'s Gas Insulated Transformer (GIT) is the most technologically advanced solution for hydro-power and underground substations, densely populated cities, mission critical substations, and offshore substations. Toshiba GITs are insulated with SF 6 gas rather than traditionally hazardous oil which risks fire, explosions, and contaminating leaks.
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.
