    In gas-insulated switch panels the most common insulating medium used between the conductors and earthed parts (housing) is sf6 gas (sulfur hexafluoride). Since it has a higher insulating capacity than air, much more compact switch panels can be built when insulating gases (such as Sulfr hexafluoride) are used.

  • 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...
