The Shukhov Tower on the Oka River (also Dzerzhinsk High-Voltage Mast, Shukhov Oka Tower) is the world's only hyperboloid electricity pylon. It is located in Russia, in the western suburbs of Nizhny Novgorod, on the left bank of the Oka River near Dzerzhinsk. The tower is one of several tower structures designed by Russian engineer and scientist Vladimir Shukhov; however, its power lines were decommissioned in 1989.
HistoryThe Shukhov Tower was a part of a 110kV three-phase AC transmission line crossing the Oka River commissioned between 1927 and 1929. For the Oka River crossing, six hyperbolic pylons (three for each powerline) were built: a 20-metre (66 ft) tall anchor pylon, a 68-metre (223 ft) tall crossing pylon on the hillier south shore, and a 128-metre (420 ft) tall crossing pylon on the lower terrain of the north shore.
In 1989, the power line was rerouted and the 20- and 68- metre pylons were dismantled. The 128 metre pylons were left intact as a monument. Today, only one of the 128-metre pylons stands as the other was illegally demolished to sell its steel in May 2005.
