GIS or Gas Insulated Switchgear | Electrical4U· SF 6 gas pressure for insulating purpose is generally kept below 2.5 bar whereas SF 6 gas pressure for interrupting purpose is ranged from 5 bar to 7 bar. As vacuum technology is not available for high voltage, so for GIS or gas insulated switchgear system above 72.5 KV, only SF 6 is used both for interruption medium and insulation.

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.
High-voltage substations | Power Transmission | Siemens ... single-pole bus ducts with a total length of 2,700 meters connect the GIS accommodated in the 85-meter-long switchgear building with the air-insulated part of the substation. The 245-kV breakers were the world's first of its kind to switch a short-circuit current of 80 kA.
What is Switchgear? | Features, Components and Classification is Switchgear? Definition of Switchgear: The apparatus used for switching, controlling and protecting the electrical circuits and equipment is known as switchgear. The term 'switchgear' is a generic term that includes a wide range of switching devices like circuit breakers, switches, switch fuse units, off-load isolators, HRC fuses, contactors, miniature circuit breakers, ELCBs, GFCIs ...
220/132kV Gas Insulated Substations at Rs 2000000/no | Gas ... consumes much smaller space comparing to outdoor switch yard. Space restraints forcing project owners to opt for Gas insulated switchgears instead of Air insulated. All switchgear components like CB, isolator, CT, PT, LA bus bars are mounted in SF6 gas filled chambers. Since SF6 gas provides much better insulation than air.Location: Kolkata - 700156, West Bengal, India
SF6 Sensors | Gas Insulated Switchgear (GIS) | smartGAS 6 sensors for gas-insulated switchgears (GIS) . The main area of application for the non-flammable gas sulphur hexafluoride (SF 6) is insulation of electrical high-voltage switchgears, transformers and cables.Although sulphur hexafluoride is non-toxic and non-flammable, its global warming potential is about 24,000 times higher than carbon dioxide (GWP=23,900).
