The specialists of the Orenburgenergo branch of Rosseti Volga (a brand of IDGC of Volga, PJSC) are repairing the 110 kV overhead power line “Iriklinskaya GRES – GPP4 Gaya.” The high-voltage power line provides electric energy to the mining and processing plant – one of the largest mining enterprises in the Southern Urals.

To increase the reliability of power supply, energy enterprises will repair 6 towers and replace more than a thousand insulators. Given the climatic conditions and the level of industrial pollution of the territory along which the power transmission line passes, power engineers use suspended insulators with an aerodynamic profile and insulators with a hydrophobic coating. Such insulators are resistant to pollution, have high operational properties and increase the stability of the power line.

Work on this section of the line is carried out as part of the preparation of the electric grid complex for the passage of the autumn-winter period 2020-2021. In total, in 2020 in the eastern regions of the Orenburg region before the start of winter, overhaul of 1,700 kilometers of power lines with a voltage of 0.4–110 kV, repair of 781 transformer substations, distribution and transformer points will be carried out. Power engineers will also conduct clearing of protected areas of power lines from overgrowth with a total area of more than 63 hectares.
