HVDC Ekibastuz–Centre
Encyclopedia
HVDC Ekibastuz–Centre is an unfinished HVDC transmission line between Ekibastuz
in Kazhakstan and Tambov
(Centre substation) in Russia
whose construction was started in 1978. It was planned to have a length of 2414 kilometres (1,500 mi), which would have made it the longest powerline of the world with a maximum transmission rate of 6,000 MW and a transmission voltage of 750 kV between conductor and ground (respectively 1,500 kV between conductors). For this line the erection of 4,000 pylons
, most 41 metres (134.5 ft) tall, were required. Several hundred kilometres were built, including a Volga crossing on 124 metres (406.8 ft) tall towers near Saratov
. However, no construction at the terminals was ever started.
