The Ekibastuz-Kokchetav-Kustanay power transmission line operated at a nominal voltage of 1150 kV from 1988 to 1991[2]. This power line was the only power transmission line of this voltage class in the world; its capacity reached 5,500 MW.
It currently operates at a voltage of 500 kV. The length of the section is 432 kilometers, mounted on supports with an average height of 45 meters. Phase division is used: each phase consists of 8 wires, forming a regular octagon in cross-section.
On the Kazakhstan section, five of the eight wires were removed and the unique 1150 kV substation equipment, manufactured in 1981-1986, became unusable; on the Russian sections the wire is preserved, but the line operates at a voltage of 500 kV.
