Professionals of Penzaenergo, a branch of IDGC of Volga, PJSC (a member of Rosseti Group), entered the final straight in reconstruction of 0.4 kV power transmission line (over 6.0 km long) in the Malaya Valyaevka settlement initiated under the 2015 Investment Program. The reconstruction campaign included replacement of two package transformer substations (with the total capacity of 260 kVA); replacement of 326 wooden poles with SV-95-3s reinforced concrete poles; replacement of bare wires with self-supported isolated wires (6.33 km); and replacement of 160 branches of residential houses and buildings. The necessity of reconstruction of this line and replacement of all components was dictated by heavy wear of the facility. Reconstruction and commissioning of the power line will contribute to reliable power supplies to consumers residing in the Malaya Valyaevka settlement, including socially important facilities, reduced failure risk and lower damage caused by power undersupply, as well as to improved quality of power supply to consumers during 2015-2016 autumn and winter season and consequent years.
