Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, gaz sf6, 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 gaz sf6 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 Sulfr hexafluoride can do in centimeters.Get price

The history of gas-insulated substations - Think Grid

Jun 13, 2012 · Their first GIS for 220 kV was delivered in 1970 and the 145 kV, 40 kA in 1971. The original circuit breakers with double pressure SF 6 systems (220 kV, 50 kA), developed together with ITE USA, were operated by the well-known Sprecher motor-wound spring operating mechanisms, which contributed to the success of subsequent GIS families. The exclusive third-generation FK mechanism today serves all Grid Solutions' GIS products on the world market.Get price
