both sets of towers were destroyed or dismantled. Between 1945 and 1949 the pylons were rebuilt using the old foundations. However, only three towers were built at each end of the span. 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 triples are capable of carrying 18 conductors for 6 150 kV-circuits, there are only 5 circuits 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.
