Gas Insulated Switchgear and GIS - EA Technology

Gas Insulated Switchgear (GIS) into Electric Power Transmission substations. The superior dielectric and arc quenching properties of SF 6 gas allow a substantial reduction in the size of the switchgear and GIS substations can therefore be smaller than conventional air-insulated substations. Enclosed active parts within GIS can also increase the reliability and safety of GIS substations.Get price

5 Differences Between Air-Insulated Substations and Gas

ConstructionInstallationOperationMaintenanceTotal Cost of OwnershipGIS high voltage substationengineering uses the gas sulfur hexafluoride for insulation, whereas AIS uses air insulation in a metal-clad system. Sulfur hexafluoride is five times heavier than air and offers excellent extinction behavior. Another significant construction-based difference between the two switchyards is that a metal-clad AIS uses three-position draw-out circuit breakers (on, off and test). GIS systems use fixed, mounted circuit breakers. The sealed mounted breakers are a ‘sealed-for-life’ technology, whereas the AIS breaker can be removed for maintenance and troubleshooting.Get price
