Danube mast
Donaumast is the name commonly used in Germany and Austria for a specific design of overhead line masts for two or four three-phase circuits , in which two conductors of a circuit are located on one crossbeam and one on the other. As a rule, the wider traverse is at the bottom and the narrower is at the top. The name goes back to the 110-kV high-voltage line that went into operation in 1927 along the Danube valley between Regensburg and the Kachlet power plant above Passau , where this mast shape was first used. However, masts had already been built in this order, for example parts of a line from Zschornewitz to Berlin built in 1918 and a 110 kV system built in Ontario, Canada in 1910.
The Danube mast arrangement is a compromise between the one- level arrangement (which requires a wider route) and the three-level arrangement (which requires higher masts).
Danube masts are the most common type of high -voltage masts for three-phase high-voltage transmission (DHÜ) for two circuits in the old federal states , while in the new federal states the single-level arrangement of the conductor cables for the 110 kV voltage level is widespread. Danube masts are also dominant for 380 kV in the new federal states.
There are a few Danube masts where the arrangement is upside down, the wider crossbeam with two conductor cables is attached above the narrower one, for example when crossing the Eyach over the facility 615 .
