Elbe Crossing 1 is a group of masts providing an overhead crossing of 220kV three phase AC Current line across the River Elbe . Constructed between 1959 and 1962 as part of the line from Stade to Hamburg north, it consists of 4 masts:
Because of the swampy underground, each mast's foundation is built on stakes rammed into the ground. The Lühesand portal mast rests on 41 stakes and the one on the Buhnenfeld on 57. In contrast to the usual construction of such Lattice Steel Pylon s the direction of the line passes diagonally over the square ground cross section of the pylon, which brought certain savings in material. The two crossbeams for the admission of the 6 conductor cables are at a height of 166 meters and 179 meters. The mast on the Buhnenfeld carries a radar facility of the navigation management Hamburg at a height of 30 meters. Each portal mast is equipped with stairs and gangways for maintenance of flight safety beacons and with a hoist for lifting heavy loads. Elbe crossing 1 was supplemented in the 1970s by Elbe Crossing 2 . EXTERNAL LINKS
