History

The powerline crossing, which was one of the first of its kind in the former USSR, was built between 1930 and 1932 and consisted originally of 4 towers on both ends of the span interconnected by a gangway equipped a railing in a height of 63.5 metres (208.3 ft). In World War II

both towers were destroyed or dismantled.

Between 1945 and 1949 the pylons were rebuilt using the old foundations. However, on each side of the span only three towers were rebuilt. The unused foundation, on which the fourth tower on Khortytsia Island stood, still exists.

Configuration

Each pylon has a single crossarm designed to carry 6 conductors. However, only 4 conductors, two at the edge and two near the pylon, are installed there. From the middle of each crossbar, half a support structure runs down to the gangway. At this point on the underside of the gangway the insulator carrying the middle conductor is fixed.

Although the triple is capable of carrying 18 conductors for 6 150 kV-circuits, only 5 circuits use it at present. A sixth circuit runs parallel to the triple on a new tubular steel monopolar powerline tower.

All towers of both triples are painted red and white and equipped with a ladder.
