Building of an air transmission line 110 kV «Kiembaj – Priisk Kumak - Svetlyi» will pass in 2 steps. Within the framework of the first stage power engineers will mount sites of air-lines 110 kV from substation " Kiembaj " to substations "Priisk Kumak". The second, more scale stage of building of a line is planned in 2012. Power engineers will mount over 67 kilometers of air line and connect substations «Priisk Kumak» and "Svetlinsky". Over 92 km of air line will be constructed during 2 years. Building of the given line has strategic character for the East of the Orenburg region. It feeds large central substations 110/35/6 kV – "Svetlinskaya" and "Priisk Kumak" which supply 15 substations of Adamovsky, Jasnensky and Svetlinsky areas, Buruktalsky metal factory and Buruktalsky Ore Administration with electric power . Also the new line will raise reliability of the work of Nasosnaya substation from which the electrical supply of the Kumaksky water intake, a unique source of water supply of a city Yasnyi and settlement Svetlyi is made.
