Supported by the construction firm Usole VSEM Cable, Irkutsk Energo, Electrical Grids of Angarsk Subdivision completed the reconductoring of the 110kV line Power Station 10 of Irkutsk – Meget – Novolenino near the town of Irkutsk next to Angarsk in Siberia, Russia to increase line capacity.

Irkutsk Energo selected 367.4 mm^2 (725 kcmil) ACCC Amsterdam size conductor to upgrade their 8.5 kilometer line originally built in 1956. The line consisted of 18 dead end towers and 22 mid span towers. Unkomtech Holding, KirsCable factory supplied 44.7 kilometers of ACCC conductor to complete the project. Burndy and PLP Belos supplied ancillary hardware. CTC Global’s Master Installer, Sergey Salnikov provided training and installation support.

The contractor used TESMEC #ARS 510; #FRS 403; and #800 equipment to help with the installation which included substantial swamp crossings. According to the local residents, the area was a forest when the line was first constructed. It has transformed into a giant swamp aparently due to climate change.

The installation began in early April and was completed at the end of September and recently energized. To maneuver through the swamp it was necessary to build wooden bridges to be able to move equipment and deliver tools. This project represents the 4th ACCC installation in Siberia.
