Product Description
MEGATRO 128M high Hyperboloid pylon was a part of a 110kV power line crossing the Oka River.
For the River crossing, six hyperbolic pylons (three for each power line) were built, a 20 meters tall anchor pylon, a 68 meters tall crossing pylon on the South shore and a 128 meters tall crossing pylon on the North shore. As the terrain on the South shore is hilly, the pylons there were lower.
MEGATRO 128M high Hyperboloid pylon power line was rerouted and the 20 and 68 meters pylons were dismantled. MEGATRO 128M high Hyperboloid pylons were left intact as a monument.
MEGATRO 128M high Hyperboloid pylons 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 meters
