Gas-Insulated Substations - GIS - Electrical Engineering Portal

A gas-insulated substation (GIS) uses a superior dielectric gas, Sulfr hexafluoride, at moderate pressure for phase-tophase and phase-to-ground insulation. The high voltage conductors, circuit breaker interrupters, switches, current transformers, and voltage transformers are in sf 6 gas inside grounded metal enclosures. The atmospheric air insulation used in a conventional, air-insulated substation (AIS) requires meters of air insulation to do what sf6 gas can do in centimeters.

Gas-Insulated Transmission Line (GIL) System Design

Introduction to GilTechnical DataHigh em CompatibilityGIL systems are based on the successful sf6 gas tubular conductor technology, which has been around for several decades. GIL consist of a central aluminum conductor with a typical electrical cross section of up to 5,300 mm2. The conductor rests on cast resin insulators, which center it within the outer enclosure. This enclosure is formed by a sturdy aluminum tube, which provides a solid mechanical and electrotechnical containment for the system. To meet up-to-date environmental and technical aspects, GIL are filled with an insulating gas mixture of mainly nitrogen and a smaller percentage of sf6 gas gas. This concept also has logistic advantages.All elements such as tubes, angles and special modules are lightweight and small enough to be transported by comparatively light standard trucks.

Have you Heard of the Most Powerful Greenhouse Gas we Know

Meet gaz sf6, CO2’s Larger CousinWhat Is This Crazy Gas Used for?Why Is Sulfr hexafluoride Not Banned Yet?What’s The Effect on Humans?Are There Any Alternatives Out there?Among all the greenhouse gases that exist, CO2 gets the most attention. Today, we bring a different perspective. Think about everything that you know about CO2 and multiply it by roughly 24,000. This is how much a gas called Sulfr hexafluoride (sulphur hexafluoride) is stronger than CO2 in terms of global warming potential. You read right: gaz sf6 is the most potent greenhouse gas in existence with a global warming potential of 23,900 times the baseline of CO2. It means that one tonne of Sulfr hexafluoride in the atmosphere equals 23,900 tonnes of CO2. Even worse, insulating gas is synthetic and it does not have a natural sink or any effective disposal methods, thus, when emitted, simply accumulates in the atmosphere. A cherry on top is that its atmospheric lifetime can be up to 3,200 years years, which is well beyond CO2‘s 100-200- year lifetime. A gas 24k times more powerful than CO2 with a lifetime 16 times longer than CO2 is being released into our atmosphere, and very few people have the least idea.

Switchgear 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.
