GIS or Gas Insulated Switchgear | Electrical4U· GIS is a kind of metal enclosed switchgear. That means, all the equipments of the electrical switchgear are enclosed by gas tight metal enclosure and SF 6 gas is used as insulation between live parts of the equipments and earthed metal enclosure. This type of switchgear, means, and gas insulated switchgear is available from 12 KV systems to 800 KV system.
Introduction to Gas Insulated Substations / Switchgears (GIS) article is an introduction to Gas-insulated Substations. Gas Insulated Substation (GIS) also called SF6 Gas Insulated Metalclad Switchgear is preferred for 12kV, 36kV, 72.5kV, 145 kV, 245 kV, 420 kV, and above voltages.

High voltage - Wikipedia dielectric breakdown strength of dry air, at Standard Temperature and Pressure (STP), between spherical electrodes is approximately 33 kV/cm. This is only as a rough guide, since the actual breakdown voltage is highly dependent upon the electrode shape and size. Strong electric fields (from high voltages applied to small or pointed conductors) often produce violet-colored corona discharges ...
Alternatives for SF6 | 2020 | Siemens Energy Global more and more often, SF 6 is no longer the gas of choice. For a simple reason: if the gas escapes, it contributes to climate change. It is around 23,500 times more warming than the greenhouse gas CO 2 and has a life span of 3,200 years in the earth's atmosphere. According to the Intergovernmental Panel on Climate Change IPCC, abandoning SF 6 completely could contribute 1.5 percent to ...
