A bit further northward this powerline crosses Tauber valley. Until 2022 the shown pylons, which were built in 1980 had only the two upmost crossbars with a single 380 kV and a single 110 kV circuit. However the pinnacles of these pylons carried until then two garland-like communication cables, one ...

The same line a few kilometres northwards west of Elpersheim. Until 2022 the 110 kV-circuits on the lowest crossbar ended at the branch pylon in the background and run from there in direction of Bad Mergentheim. In 2022 the lowest crossbar was installed on the pylons in front of the branch tower inc...

At the next pylon the 110 kV-branch starts. This branch pylon is remarkable as it is a strainer for the 110 kV-circuits and a suspension tower for the 380 kV-circuit. Until 2022 on this pylon and the next in the line two garland-like communication cables were installed: one on the ground conductor a...

Tower 73 of powerline Kupferzell-Rittershausen northwest of Niederstetten. Originally, the tower carried a garland-like communication cable at its ground conductor, but in 2022 this was replaced by a ground conductor with integrated communication cable

Although the following two pictures did not show a powerline, but instead the way of an aerial cable car, I do not want to keep them from the forum as they look too nice. The pictures show the Neckar river crossing of Mannheim aerial cable car, which interconnects "Luisenpark" and "Sp...

The small 110 kV-line in the background had originally two circuits (6 conductors). One circuit was used for the 110 kV-link from Birkenfeld to Pulverdingen substation, the other for the 110 kV-link from Birkenfeld to Pforzheim Cogeneration Plant. In 2003 the 110 kV-line from Birkenfeld to Pulverdin...

I have no information, if these pylons were originally designed for lower voltages. I also do not know, why the distance between the lowest and the medium crossbar is larger than that between the medium and the topmost crossbar. In my opinion the old design for pylons of lines carrying two 380 kV-ci...

The next towers of the line were not realized on August 23rd, 2023. Interestingly Tower 30, which is a tubular steel tower north of Pforzheim-Eutingen, is completed. It has as the unfinished Tower 20 crossbars and ground conductor pinnacles implemented as lattice steel elements. The tower has some s...

The next tower of the line is still under construction, but it is from special interest, as it is a tubular steel structure and not a lattice structure. When completed, it will be as the previous tower be capable of carrying two 380 kV and two 110 kV-circuits.

On August 23rd, 2023, when the picture was taken, the conductors end at the strainer carrying the number 19. It is temporarily anchored in eastern direction with multiple guys, obviously in order to avoid too large horizontal forces on its structure and its base.
