Railway power line Neckarwestheim – Zazenhausen

Railway power line with bundles of four

The Neckarwestheim – Zazenhausen traction power line is a traction power line built in 1977 in Baden-Württemberg . The 26-kilometer-long line operated by DB Energie leads from the traction current switchgear in Neckarwestheim ( Lage ) to the central feed point in Stuttgart-Zazenhausen ( Lage ). Special features are the largely hybrid line and the use of four bundles . Each conductor of the bundle of four has an aluminum cross-section of 300 mm² and a steel cross-section of 50 mm². 49.0428 9.201448.8445 9.1853

The line begins at the Neckarwestheim switchgear, to which the traction current line from the Neckarwestheim nuclear power plant is also connected. Together with this, it runs for the first kilometer south on the same pylons, parallel to three-phase lines on the 220 and 380 kV level. On the area of the Schloss Liebenstein golf course , this branches off to the west together with a two-circuit 380 kV three-phase current line and ends at a traction current converter plant built in 2010/2011. The masts of this line have five cross members (one earth cable cross member , three for three-phase current and one for traction current). The traction current line in the direction of Zazenhausen swings onto the lowest crossbeam of a hybrid line being created here , whereby the lines to the Hoheneck substation are crossed under . The hybrid masts is Danube masts with an additional lower beam for traction power.

As far as the Neckar, southwest of Pleidelsheim , this line runs parallel to the north-south line and the 220 kV Neckarwestheim – Hoheneck line before it branches off in a south-easterly direction to bypass Ludwigsburg to the east. At the level of the Marbach power station , the Neckar is crossed a second time, then some masts with only two traverses (one for traction current, one for three-phase current) are used around the two extra-high voltage lines from Hoheneck to the Wendlingen substation and the 110 kV line To cross under Marbach– Winnenden . A very unusual crossing mast was erected here in 2012 . This is similar to a junction pylon , with another traverse for the traction power line being built under the junction. This happened due to the planned conversion of a circuit from Neckarwestheim to Wendlingen to 380 kV.

East of Neckarweihingen , the Neckar is crossed for the third time. It then runs parallel to the 110 kV Hoheneck– Altbach line to Aldingen , where it turns in a south-westerly direction. Because of the former military airfield in Kornwestheim (today the Pattonville settlement ), low masts with only two trusses are used in this area.

South of the airfield it meets another hybrid line (combined three-phase / traction current line from EnBW ), which follows next to it to Kornwestheim. Originally, this was a branch of the Hoheneck – Wendlingen 220 kV line from the 1930s (part of the Black Forest line ). After this line was dismantled in 2007/2008, the branch was converted for 380 kV and, at the same time, the Zazenhausen - Plochingen traction current line was re-laid on the lower traverse . This newly routed line now uses parts of the old masts of the 220 kV line to Wendlingen. The original route through Zuffenhausen was dismantled.

Originally, both 220 kV circuits of the lines coming from Neckarwestheim and Hoheneck / Wendlingen ended at the Kornwestheim switchgear station, where a 220 kV line continued to the Seewiesen substation. From 2008 to 2009 it was converted into a 380/110 kV substation and the line from Hoheneck / Wendlingen was connected to it. The line to Seewiesen was converted to 110 kV. Temporarily, the 220 kV line from Neckarwestheim ended blindly due to a lack of connections. It was not until 2013 to 2014 that this was also converted to 380 kV and connected to the substation. Today one circuit leads from Neckarwestheim to the junction pylon built in 2012 near Marbach and on to Wendlingen, the other to Kornwestheim. The line masts south of Marbach were also converted accordingly. To the west of Aldingen, the 110 kV line Hoheneck – Altbach was laid on the same mast and two new 110 kV circuits were set up between Marbach and Kornwestheim.

The new masts have a very unusual structure: the 380 kV circuit and a 110 kV circuit run on the top crossbeam. Instead of the earth rope tip common in Germany, earth rope horns are used with a total of two earth ropes , similar to the masts in the new federal states . Just below this is a small one-sided cross-member for another 110 kV circuit. This is followed by the traverse for traction current and then, in sections, a 110 kV traverse. Since the Pattonville airfield can still be used, double warning markers were installed on the earth ropes. Shortly before Kornwestheim, the original masts were left, but roped accordingly.

Behind the Kornwestheim switchgear station, the traction current line to Zazenhausen runs the only part on its own masts before it reaches the Zazenhausen central feed point, which houses a substation as well as a load distributor.
