The branch “Rosseti Centre Tverenergo” developed a unique design solution for the restoration of a damaged line in difficult terrain


Power engineers of “Rosseti Centre Tverenergo” commissioned the 110 kV “Redkino-Bezborodovo-1” overhead line (Conductor), which was damaged by a gale in the Konakovsky district of the Tver region. Disaster recovery work was carried out from 4 to 6 April.

Due to the fact that the steel structure is located in an impassable peat marshy area, the power engineers of the Tver branch of Rosseti Centre developed a special design solution. For its implementation, the transportation of highly passable equipment to the place of work was carried out by specialized low loader trailers through towing, accompanied by representatives of the regional General Directorate of the EMERCOM of Russia.

Also, due to the impossibility of crew vehicles to travel, personnel were delivered by tracked vehicles.

The old damaged power facility was dismantled, after which, at the site of the technological violation, the power engineers assembled and installed a new 110 kV pole with installation of an additional unit that prevents capsizing in wetlands.

The work was carried out around the clock using light towers, bulldozer and cross-country vehicles. In total, 18 people, 2 bulldozers, an aerial work platform, a crane drilling machine, a truck crane with a lifting capacity of 25 tons and a tracked vehicle were involved in the recovery event.

Also, to organize the speedy restoration of the damaged section, assistance to the power engineers was provided by “Rosseti FGC UES” - Valdai PMES, which involved an aerial work platform with a highly qualified crew.

Damage to the metal structure did not affect the power supply to consumers, which during the period of work were powered by a backup circuit. Currently, the line is energized, the electric grid complex in the municipality operates without technological failures.

“The section of the overhead line on which the power transmission line pole fell is strategically important for the Konakovsky district, since it provides transit of electricity to the Moscow region and to the substations from which the railway nodes supplying Sapsan trains on the Tver-Konakovo section are powered,” comments First Deputy General Director - Chief Engineer of Rosseti Centre - the managing organization of Rosseti Centre and Volga Region Alexander Pilyugin. “The prompt and well-coordinated actions of the employees of Rosseti Centre, Rosseti FGC UES and the regional General Directorate of the EMERCOM of Russia made it possible to restore the damaged section of the 110 kV overhead line as soon as possible in difficult conditions under the storm warning in the region and ultimately to prevent the development of a system failure”.
