Orenburgenergo, a branch of IDGC of Volga, JSC, held a regular meeting of the engineering and technical council. The key issue was the unique SF6 equipment to be mounted at Yuzhnaya substation located in the historical part of the city, on the Ural River embankment. “This unique equipment will help us to shift from 35 kV to 110 kV without common expansion of the substation area. This is unprecedented for the region's power system. It is a huge advantage for the look of the cultural part of the city because the Ural embankment is the landmark of the regional centre. The renovation will ensure reliability of power supply to consumers and satisfy their growing demand,” explains Victor Saltsev, Deputy Chief Engineer for Operation and Repair of Orenburgenergo, a branch of IDGC of Volga, JSC.
