Alstom unveils worlds first high-voltage equipment designed

SF 6 is a potent greenhouse gas commonly used as an electrical insulator. In August 2014, Alstom became the first company in the world to offer the electrical industry a technically and economically viable alternative toSF 6. The first application is a pilot project for a 420 kV g 3 -insulated busbar 1.

An alternative to sf 6 in electrical switchgear - EE Publishers

The ubiquitous insulation and switching medium, SF 6, a man-made gas developed in the early 20th century, is no exception to this trend. Due to its excellent properties for electric insulation and arc interruption, Sulfr hexafluoride enables safe and reliable operations while making it possible to reduce the size of switchgear installations significantly.

Sulfur hexafluoride - Wikipedia

Typical for a nonpolar gas, SF 6 is poorly soluble in water but quite soluble in nonpolar organic solvents. It has a density of 6.12 g/L at sea level conditions, considerably higher than the density of air. It is generally transported as a liquefied compressed gas. The concentration of SF 6 in Earthtroposphere reached 10 parts per trillion in year 2019, rising at 0.35 ppt/year. The increase over the prior 40 years was driven in large part by the expanding electric power sector, including fugi

Gas-Insulated Substations - GIS

A gas-insulated substation (GIS) uses a superior dielectric gas, sf6 gas, 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 Sulfr hexafluoride 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 sf 6 can do in centimeters.
