GIS Substations Stabilize Power Supply in Sandstorm Regions

To help improve power supply in Ahvaz, Khuzestan Province, and reduce load shedding and frequent outages, three gas-insulated substations have been built and are being synchronized with the national grid, managing director of Ahvaz Regional Electricity Company said.
"GIS systems cost twice as much as regular substations but play a key role in reducing power cuts in sandstorm regions," Mahmoud Dashtbozorg was quoted as saying by the Energy Ministry news portal. The three 132-kilovolt substations cost $35 million and were built in two years.
