220kv gis substation leak rate

220kv gis substation leak rate

The Cape Lambert Bulk Supply Substation (CLBSS) was conceived in 2008 as a traditional air-insulated switchgear (AIS) substation to be located in open bushland near the town of Wickham in the Pilbara. After the GFC, the substation evolved into a 9-bay 220kV gas-insulated switchgear (GIS) substation
