The next tower of the 110 kV-line Echterdingen/Nord - Böblingen/Ost in direction Böblingen is Tower 13 of Facility 9219. It is a strainer with two crossbars. The communication cable, which starts at the pylon showing in my previous posting runs to this tower and can be seen on my photograph left of the structure of the pylon.

Kupferzell substation is a 380 kV/110 kV/20 kV-substation north of Schwäbisch Hall. Originally, it was a 110 kV/20 kV-substation, but at the end of the 1970ies, it got a 380 kV switchyard and was turned into 380 kV/110 kV/20 kV-substation.
While its 110 kV switchyard is a common open-air switchyard, its 380 kV switchyard is an indoor SF6-switchyard - a new technology at its construction time. For a better overvoltage protection of this switchyard, all 380 kV-lines carry in the proximity of Kupferzell substation at least two ground conductors - either on a crossbar over the crossbars with the conductors or on an enlengthened top crossbar. Three 380 kV-lines start at Kupferzell substation - one to Goldshöfe, one to Grossgartach and one to Grafenrheinfeld over Stalldorf substation.

While the first tower of the 380 kV-line Kupferzell-Stalldorf-Grafenrheinfeld carries only its conductors, starting at the second tower, which is shown on the picture, the towers of this line carry until Tower 63, which is situated southeast of Adolzhausen, also the two 110 kV-circuits of the line from Kupferzell to Niederstetten.
Until 2022 at this tower also two garland-like communication cables, which were fixed at the ground conductors started, but these were replaced by ground conductors with integrated communication cable.

The next tower, tower 3, is the first suspension tower of the line.

The 380 kV-line Kupferzell-Stalldorf-Grafenrheinfeld running morthward. One can see tower 3 (right), tower 4 (left) and tower 5 (left at the edge) of the line.

The 380 kV-line Kupferzell-Stalldorf-Grafenrheinfeld has until tower 12 a crossbar for the ground conductors above the crossbars for the conductors. Until 2022 communication cables were fixed like garlands at these ground conductors. In 2022 ground conductors with integrated communication cables were installed, which end at tower 12. The cables run on the ground conductor crossbar to the body of the pylon, where they are brought together to a single cable.

The next tower of the 380 kV-line Kupferzell-Stalldorf-Grafenrheinfeld in northern direction, which carries the number 13 and which has a height of 67.03 metres, is the southern terminus of the 994.7 metres long span across Kocher valley.

Through its lakes one can see the powerline span across Kocher valley.
