Branch of OAO "UES FGC" — Trunk Power Grids of the South — has completed construction of three cable lines (CL) of 110 kV in the Imereti lowland, which will provide transmission of power of the newly constructed Adler CHPS.
The new generation facility is designed to solve the problem of energy shortage and the city of Sochi, will also be a second source of power supply for the Olympic Park, and if necessary, be able to exercise the power of sports facilities for new lines even complete loss of connection to the grid.
The total length of 110 kV Adler CHPS — Imereti, of 110 kV Adler CHPS — Ice Palace and 110 kV cable line Adler CHPS — Fun is 12.4 km. At the intersections of the lines with the federal highway "Dzhugba-Sochi", with the railroad tracks, as well as outbuildings equipped with three special micro-tunnels underground. Their length is 241 m, 137 m and 451 m, and the cable is laid at a depth of 6.9 to 29.3 m
CL built MES South, equipped with sensors of the innovation system of automatic diagnostics that will produce continuous analysis of the technical condition of the lines. Under the ground and laid fiber-optic communication line (FOCL).
Cable lines are more reliable and easy to operate than air, they are designed to the highest environmental and safety standards. Insulation of cable products made from cross-linked polyethylene, which is celebrated among the benefits of significantly higher throughput, high strength, low weight, and a smaller diameter and bend radius compared to the previously applied oil-filled cables.
Implementation of the project of construction of cable transmission lines 110 kV in the Imereti Valley began in 2010. In 2011, OAO "UES FGC" has completed the construction of visits 220 kV overhead line Psou — Dagomis at the Adler CHPS. This enabled the transmission of electricity power plants to consumers Adler district of Sochi.
OAO "UES FGC" carries out building and renovation of 33 main power supply facilities for electricity Olympic Winter Games in 2014 in accordance with the deadlines established by the International Olympic Committee and the Program for Construction of Olympic Venues and Development of Sochi as a mountain resort.
