Summaryedit

Description
English: Shukhov Towers on the Oka River - hyperboloid diagrid shell electricity pylons.
  • The Shukhov Towers were a part of a 110kV powerline crossing the Oka River. Between 1927 and 1929, two parallel-running, 110kV, three-phase AC powerlines designed by Russian engineer and scientist Vladimir Shukhov were built there.
  • For the Oka River crossing, six hyperbolic pylons (three for each powerline) were built, a 20 metre tall anchor pylon, a 68 metre tall crossing pylon on the South shore and a 128 metre tall crossing pylon on the North shore. As the terrain on the South shore is hilly, the pylons there were lower.
  • In 1989 the powerline 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.
  • The Shukhov Towers each consist of five 25-metre steel lattice sections, formed by single-cavity hyperboloids of revolution. The pylon sections are made of straight profiles, the ends of which rest against circular foundations. The tower's circular concrete foundation has a diameter of 30 metres.
