coke backfill is used. The electrode lines, which look like a 110 kV-powerlines with 2 conductors, use similar, but smaller pylons as the main line. In opposite to the main line, all strainers are free-standing lattice towers with a single crossbar, while the suspension towers of the electrode line are usually concrete poles with a single crossbar made of steel. Only suspension towers of extraordinary height are built as lattice towers. The electrode of Mikhailovskaya converter station is situated north of Smile at . It is connected with Mikhailovskaya converter station by a 32 kilometre long overhead line, which consists of two parallelized 2450 mm2 ACSR conductors. The electrode line from Mikhailovskaya converter station follows the main line on the left side seen from Mikhailovskaya converter station until a point northeast of Zolobok at where it undercrosses the main line. After this point, it follows the main line on the other site until a point south of Krymske at where it leaves the course of the main line in southeast direction toward the electrode. The electrode for the terminal at Volgograd is situated northwest of Kamennyy at . It is connected with it by a 24 kilometre long overhead line consisting of two parallelized 2450 mm2 ACSR conductors. Tower at this location, 48.830929N, 44.653909E, completely removed between Oct 2021 and Jun 2022 on Google Earth images. Additional towers also removed until & over rail crossing. 48.827546N, 44.665425E last remaining tower at hydroelectric dam. Trivia HVDC Volgograd–Donbass was the first long-distance HVDC link without a submarine cable section HVDC Volgograd–Donbass is the only HVDC scheme in Europe implemented as overhead line in its whole length HVDC Volgograd–Donbass is the only long distance HVDC system operational in Russia. The experimental Moscow–Kashira scheme has been shut down and the planned ±750 kV, 2400 km Ekibastuz–Tambov scheme, which would have had the longest transmission distance and highest voltage in the world at the time, was never completed because of the collapse of the Soviet Union in the early 1990s. Waypoints Right of way of HVDC Volgograd–Donbass, according to Google-Maps. May be imperfect due to low resolution.
