The Top 25 Gas Insulated Substation (GIS) Companies

Nov 27, 2017 · The Gas Insulated Substation (GIS) is a compact assembly consisting of multiple components enclosed in a metallic covering with compressed sulphur hexafluoride (Sulfr hexafluoride) gas as an insulating medium.

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
