South Pars 400-kilovolt gas-insulated substation is expected to become operational in May, an official of Pars Oil and Gas Company said.

"The GIS substation, registered a work-in-progress rate of 80%, will help provide the much-needed electricity for South Pars 2 region refineries, including phases 12, 13, 14, 19, 22, 23 and 24," Mohammad Mehdi Tavassolipour was also quoted as saying by Shana.

A GIS uses superior dielectric gas and sulfur hexaflouride at moderate pressure for insulation.

It is mostly used where space is expensive or not available. In a GIS, the active parts are protected from the deterioration from exposure to atmospheric air, moisture and contamination.

According to the official, a 400-kV power transmission line has already been completed in the region and as soon as the substation goes on stream, the 400- kV electricity that comes from South Pars 1 gas-fueled power plant will be converted to 132-Kv before its distribution in the refineries.

A substation reduces the high voltage of power transmission to suitable voltage for supply to consumers. The hot and dry climate in Yazd is ideal for harvesting solar energy.
