Elbe Crossing 1

The Elbe crossing 1 is a built between 1959 and 1962 overhead line crossing the Elbe and the 220 ​​- kV three-phase line Stade -Hamburg- Nord.

Execution

The Elbe crossing 1 consists of four pylons:

• Two executed as a portal masts tension towers of 50 m height with a crossbar in 33 m. One of these poles is at the Schleswig-Holstein side of the river, the other on the side of the Elbe in Lower Saxony in the Old Country.
• Two identical suspension towers of 189 meters with 330 tons of weight in order to guarantee the required vertical clearance of 75 meters on the river Elbe. One of these towers stands on the Elbe island Lühesand, the other on Julssand, a former river island near the Hetlinger ski jump on the Schleswig-Holstein side of the river. Because of the marshy subsoil both masts were carried out as pile foundation. Here, the mast rests on the island Lühesand to 41 and the. Groynes on the field on 57 piles In contrast to commonly used in pipeline construction practice, the corner posts of these masts are diagonal to the direction of the line, which brought certain material savings. The two beams for the inclusion of the six conductors are located at an altitude of 166 m and 179 m.

The span between the supporting masts above the Elbe is about 1140 m.

The mast at Julssand carries in 30 m height a radar installation of the water and Shipping Authority Hamburg. Both masts are equipped with stairs and catwalks for maintenance of flight safety lights and a winch to lift heavy loads.

The Elbe crossing 1 was supplemented in the 1970s by the Elbe crossing 2.
