Zaporizhzhia Pylon Triple

The Zaporizhia Pylon Triple is a set of two triples of 74.5 metres (244 ft) tall electricity pylons extending over the Dnieper River standing on a 27m rock in Zaporizhia, Ukraine. They are used for the transport of electricity generated at the Dnieper Hydroelectric Station over a span of 900 metres from Khortytsia Island to the east bank of Dnieper River. The two triples are an unofficial landmark of Zaporizhia.

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 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.

gollark: It might be running better than yours because the display is lower resolution.
gollark: It has an i5-7200U, 8GB of RAM, and the integrated HD 620 graphics.
gollark: Zachary's laptop is my old one so I of course know the specs.
gollark: It doesn't? Mysterious. It has extremely low end graphics.
gollark: Probably those "microstutter" things where some frames take a lot longer due to ??? garbage collection.
