IDGC of Centre increases the reliability of the distribution grid of the Kursk region

Until the end of 2012 IDGC of Centre is planning to invest more than 1 billion rubles in the construction and modernization of power facilities of the Kursk region, to put into operation 200 km of power lines and 49.7 MVA transformer capacity.

Major investments in the region are associated with the growth of energy consumption, which requires massive financial investments in distribution networks.

One of the important projects of the investment program of IDGC of Centre — Kurskenergo division for this year — large-scale reconstruction of the 110 kV overhead line (Conductor) “Garden-Device — Garden-Boiler” (two circuits of one 110 kV Conductor).

The modernization of a four kilometer section was performed to increase the transmission capacity of the line, improve the quality and reliability of the transmission of electricity, generated by combined cycle gas turbine (CCGT) of the boiler in Northwest district, to transit substations “Garden”, “Ore”, and “Phosphate”.

These substations provide power for more than 10 thousand residents, industrial enterprises, such as CJSC “Gotek”, ZHBI-3, Gormolzavod (city of Zheleznogorsk), Cardboard Plant (city of Kursk) and Kursk Water Intake.

"Given that the ROW of the line passes through a populated area, crosses the Victory Avenue in Kursk and a highway with trolleybus traffic, goes across the pond with a span of 306 metres, intersects with the 330 kV overhead line, the best forces and staff of Kurskenergo and contractors were involved to perform the work, — stressed Head of capital construction of IDGC of Centre — Kurskenergo division Gennady Khardikov.

The line reconstruction project provided for the replacement of existing reinforced concrete intermediate poles PB 110-6 for intermediate poles PB 110-8 and PPM 110-2f, which provide the required distance from the wires of the power lines to the ground and anchor pole # 5 for the pole of the brand U110-2+5 to provide the required distance (11 metres) from the wires of the power lines to the road with trolleybus movement.

For mounting wires and lightning protection cable of the overhead line to the poles supporting and tensioning bunches are used consisting of cap-and-pin suspension insulators, as well as adhesion, supporting, tension and contact fitting.

The reconstructed line was secured against vibration of wires exposed to wind and icing loads: multifrequency vibration dampers are installed on the ends of spans. All metal structures of the poles are protected against corrosion by factory fabricated hot dip galvanizing.

The facility was commissioned and became a reliable link in providing electricity to consumers of the Kursk region.
