The 110 kV line Anklam – Bansin is the first 110 kV line connection between the island of Usedom and the mainland. The second 110-k V - high-voltage line that connects Usedom to the mainland, only in 1950 was added and crosses east of Kröslin the Peenestrom .

history

In 1900 electrification also reached Anklam. Up until now there were local producers of direct current , now an overland control center for the three-phase current has been built here from Friedland . In 1910, the provincial parliament for Pomerania was the first province in Prussia to decide on full electrification. In 1911 the overhead lines in Pomerania were put into operation. The exact date or year of the connection via the overhead line to Usedom has not yet been determined, but it will also have been around 1911. From the overland control center - today the substation - in Anklam, the line ran east towards Kamp and then went to the Peenestrom. The overhead line crossing will not have looked like it did today. The construction took place at the narrowest point of the river between Kamp and Karnin. Masts and lines had to be constantly renewed and modernized. At times there were two overhead line crossings, one for medium voltage and one for 110 kV.

Until 1950 it was the only civil service route to the island of Usedom. It supplied the island with electricity. When the construction of the HVA-Peenemünde began in 1936 , the power plant was built soon afterwards, but only for the HVA. In 1945 the undestroyed power plant had to supply electricity again - now for civil use. However, the output was too high to supply the island, so that in 1950 the Peenemünde - Kröslin overhead line was built to supply the surrounding mainland with electricity.

course

The two-system line route begins in the 110 kV substation in Anklam ( 53 ° 51 ′ 8 ″ N, 13 ° 39 ′ 47 ″ E ) , runs south past the city and reaches the Peene River crossing and thus the island of Usedom near Karnin ( 53 ° 50 ′ 45 ″ N, 13 ° 51 ′ 24 ″ E ) . Then it leads northwest past the place Usedom. At Morgenitz the route turns to the east ( 53 ° 55 ′ 14 ″ N, 13 ° 58 ′ 17 ″ E ) and at Benz to the northeast ( 53 ° 56 ′ 22 ″ N, 14 ° 5 ′ 52 ″ E ) , where it turns Bansin substation ( 53 ° 57 ′ 39 ″ N, 14 ° 7 ′ 37 ″ E ) and ends there.

Crossing the Peene River

The Anklam – Bansin route crosses the Peene River about 160 meters northwest of the remaining fragment of the Karnin lift bridge . The two 85-meter-high crossing masts designed as barrel masts are located in Kamp ( 53 ° 50 ′ 31 ″ N, 13 ° 50 ′ 54 ″ E ) and Karnin ( 53 ° 50 ′ 49 ″ N, 13 ° 51 ′ 30 ″ E ) . The masts have ladders for ascent and catwalks on the trusses. The span of the crossing is 780 meters.

Until around 2002 these masts were lower and a 20 kV medium voltage line on delta masts ran parallel to the 110 kV line . In addition to the Karniner Bridge, it had an intermediate mast on the foundations there, which also served to directly power the lift bridge, as there was a transformer station at the foot of the bridge. This line was dismantled during the modernization work after 2002 and the masts of the 110 kV line were enlarged to their current height.

With the exception of the Peene River crossing, the entire line is laid on masts with a one- level arrangement . To the west of the Peene river crossing on the mainland, modern masts of the GDR design are used, which have wider cross members than their West German counterparts and are equipped with two earth ropes. The original masts of the line are, however - unique in Germany - designed as rope-braced structures. These are similar to delta masts , with the branch of the two inclined supports being on the ground. Compared to other masts - not only in the course of the line, but also to most of the overhead line masts in Germany - they are very narrow and light.

In the 1970s, consideration was given to making the design used here the standard design in the GDR. However, this plan was abandoned because this type of construction is not suitable for future renovations and the land consumption is higher because of the foundations required for the bracing.

Aerial photographs from 2001 show that the entire line was originally built on such masts.

Such masts are often used in some countries such as Sweden because of their lower construction costs, but they are rarely found in Central Europe because the guy ropes, including the foundations required for their use, hinder agricultural use and there is a risk of damage from agricultural machinery. This is why these masts are exchanged during reconstruction, for example in the area of ​​Anklam only masts with normal foundation are set (see photo).
