5 Differences Between Air-Insulated Substations and Gas

ConstructionInstallationOperationMaintenanceTotal Cost of OwnershipGIS high voltage substation engineering 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...
