Three-phase line Ekibastus – Kökschetau
The three-phase line Ekibastus - Kökschetau - Qostanai ( Russian Экибастуз – Кокчетав – Кустанай ) is an overhead line for electrical energy transmission with a nominal voltage of 1150 kV, which is unique in the world and is operated by the Kazakh energy supplier KEGOC . The power is given as 5500 MVA. It is part of the overhead line from Itatsk, Siberia to Chelyabinsk (Челябинск) in the Urals . The line uses bundled conductors with eight individual conductors each.
Construction began in 1980, and it was partly put into operation in 1985 and 1988. This power line runs from the Ekibastus power plant over approx. 700 km to Qostanai in Kazakhstan and is mounted on triangular high-voltage pylons 60 m high. By expanding to the east, the cheaper night-time electricity from Siberia can be used due to the time difference in the Urals.
