GIS substations - Hitachi ABB Power Grids

Hitachi ABB Power Grids substations with gas-insulated switchgear (GIS) are unmatched when it comes to compactness, reliability, efficiency and safety, ensuring maximum power availability for utility, commercial and industrial customers. The robust and low maintenance GIS based design minimizes the substation’s footprint by as much as 70 percent, enabling it to be installed indoors, in busy urban areas and in harsh environments.Get price

Gas-Insulated Substations - GIS

Nov 10, 2010 · A gas-insulated substation (GIS) uses a superior dielectric gas, sf 6, 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 sf6 gas can do in centimeters.Get price

GIS | High-Voltage Gas Insulated Switchgear Substations

A gas insulated substation (GIS) is a high voltage substation in which the major structures are contained in a sealed environment with sulfur hexafluoride gas as the insulating medium. GIS technology originated in Japan, where there was a substantial need to develop technology to make substations as compact as possible. The clearance required for phase to phase and phase to ground for all equipment is much lower than that required in an air insulated substation; the total space required forGet price
