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 , 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 tall, were required. Several hundred kilometres were built, including a Volga crossing on three tall towers near Saratov, which were erected between 1989 and 1991. At Ekibastuz construction work at the terminal was started, while it was not the case at Centre substation, Tambov. == Sites == * Centre Substation: * Gryazi Substation * Volga Crossing: * Ekibastuz Electrode Line Branch: * Ekibastuz HVDC Static Inverter Plant: 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「HVDC Ekibastuz–Centre」の詳細全文を読む スポンサード リンク
