MOESK Has Increased Quality and Reliability of "Vnukovo" Airport Electricity Supply

Within the investment program, the branch of JSC "MOESK" High-Voltage Cable Grids completed the works at the facility: "Reconstruction of cable lines (CL) of 110 kV" “Choboty-Polyot 1,2" in the shortest time.

As part of the cable line reconstruction, the oil-filled cable of high-pressure with the current conducting core with the section of 625 sq. mm was replaced by modern cable with cross-linked polyethylene insulation (city cable made by "NKT Cables", Germany) with the section of 630 sq. mm

The total length of the reconstructed area was 7,145 meters, more than 14,000 meters of cable were laid there, 90 mounted couplings and 12 terminations were installed.

It was decided to use city-cable for the reconstruction of the cable line "Choboty – Polyot 1,2" with output of capacity to the airport "Vnukovo", which significantly reduced the cost of construction, reduced the period of works, increased the transmission capacity partly, and, most importantly, improved the reliability of power supply,” the director of the branch High-Voltage Cable Grids Eduard Podadaev said.

The city cable – the three-core cable – has become a frequent practice abroad. It is laid in the already existing pipeline that provides mechanical protection of the cable and significantly reduces costs for relaying cable lines, because it excludes the most part of the construction works. As a result of the city cable application, the costs for maintenance of the cable line are cut significantly.

The reconstruction was performed by the contractors - JSC "Moskabel'set'montazh" (subsidiary of JSC "MOESK") and LLC PSF "SMKS" (production and construction firm “Spetsmontazhcabel’story”). The cable line passes along the territory of the Western and Novomoskovsk administrative districts of the capital. In addition to the power delivery to the airport "Vnukovo", commissioning of CL "Choboty - Polyot" will improve the quality of electricity supply of these rapidly developing urban districts, as well as will ensure the grid connection possibility for new consumers.
