1150 kv transmission line in the chelyabinsk region

            In the eighties, the construction of the power transmission line-750 kV became widespread. On the agenda was the development of new, previously non-existent in the world voltage classes -1150 kV AC and 1500 kV DC, called ultra-high.

The construction of ultra-high-voltage transmission lines opened up exciting prospects - the ability to quickly, with minimal losses, transfer electricity and power for thousands of kilometers from energy-surplus regions of the country to energy-deficient ones.

The world's first "latitudinal" transmission lines were to link together the five unified power systems of the Soviet Union-Siberia, Kazakhstan, the Urals, the Volga, and the Center. The power transmission line Siberia-Kazakhstan-Ural was built and put into operation in stages
On March 24, 1977, the Central Committee of the CPSU and the Council of Ministers of the USSR adopted Resolution No. 243 "On the establishment of the Ekibastuz Fuel and Energy Complex and the construction of a 1500 kV DC power transmission line Ekibastuz-Center". This resolution provided for more efficient development of the fuel and energy complex, implementation of the energy program of the USSR, where Kazakhstan was provided for in the coming years one of the key roles in the Soviet energy sector. At that time, Kazakhstan ranked third among the republics of the USSR in terms of electricity production.

Given the myriad coal reserves and the scale of its production, it was decided to build large thermal power plants in Ekibastuz in the immediate vicinity of the mines, in order to minimize the cost of coal transportation. With the commissioning of power units at the GRES under construction, Kazakhstan not only fully provided electricity to the national economy of the republic, but also had the opportunity to transfer electricity to other regions of the former Soviet Union.

So in 1987, the section of this line from Ekibastuz to Chebarkul with a length of 432 kilometers was commissioned at a voltage level of 1150 kV. No other line in the world is capable of operating at such a high voltage. The site was supposed to deliver power from the two Ekibastuz GRES built to the 1150 kV substation in Chebarkul. Dispatch name: Kostanay-Chelyabinsk. The capacity of the line reached 5500 MW.

Laid from Ekibastuz through Kokchetayev and Kustanai up to Chelyabinsk, the power line-1150 connected the power systems of Kazakhstan and Russia. The average height of the line supports is 45 meters. The weight of the conductors is approximately 50 tons.

The unique high-voltage power transmission line "Siberia-Center" with a design voltage of 1150 kV cost the country 1.3 trillion rubles. rubles'. At the same time, the construction of a 1500 kV DC power transmission line Ekibastuz – Center was underway.
On the territory of Kazakhstan, the 1150 kV Ekibastuz-Kokchetav-Kustanai transmission line operated at a nominal voltage of 1150 kV from 1988 to 1991.

The completion of the "latitudinal" transmission lines of 1150 and 1500 kV was planned in 1995, but due to the collapse of the USSR, the project remained unfinished. Most of the line was "abroad", as approximately 1400 of the 1,900 km of the line "Barnaul-Ekibastuz-Kokchetav-Kustanai-Chelyabinsk" is located in Kazakhstan.
