It's a single circuit tower with a triangle shape wires.
This triangle tower or cactus tower looks like Hollandish silhouette with first two upper arms.

I know. But the question to Toliman was, if he knows if these pylons are still the original pylons from the year 192x or if they were reconstructed because of the age. On Google they look quite fragile like most pylons from the 1920s, so these could be the oldest 110 kV transmission towers in Baden-Würtemberg (or even in Germany), which are still in service.

I have no information concerning the age of the 110 kV-powerline from Karlsruhe to Pforzheim. As I know this line should be dismantled when the 380 kV-branch to Pforzheim is operational and that the 220 kV-line from Karlsruhe to Pforzheim should then run with 110 kV. It should then also feed the substation of Langensteinbach with 110 kV.

If it doesn't mind, a photo of this old 110 kV power line would be on my wishlist then.

The Mehrum power plant gets a new 380 kV substation! The power plant will be decommissioned, so the 220 kV lines to Hannover will be feeded by this substation then.

It connects the existing line Vechelde - Hameln. From Mehrum, there are several power lines to Lehrte, so...

the old 220 kV connection between Vechelde - Lehrte (right) would be obsolete after completion of the 380 kV substation.
Some dutch Donaumast pylons I have seen here always resemble me to the design of the 220 kV power lines near Lehrte.

The Bahnstrom power line near Sehnde is renewed. Seems that only 2 circuits of the 4 remain. The other power line is the connection Lehrte - Sandershausen, in background a 4x110 kV line.

Tower 145 of powerline Hoheneck-Herbertingen west of Ehningen. The line was recently sold from Amprion to Transnet and will be kept workable in next time although it is not connected to the grid at present.

Base of Tower 146 of powerline Hoheneck-Herbertingen. One can see several versions of conductor arrangement signs at the base. One obviously did not take much care in removing past conductor arrangement markings at the base. A consequence of its relatively remote location?

The pylon on the following picture is not part of a single-phase AC line of the German Railway Company or a pylon of an HVDC line. It is the tower 1 of Facility 1360 in Leingarten, which connects the substation Grossgartach of Transnet with the substation Grossgartach of Süwag. Facility 1360 uses a single pylon, which is shown on the picture.
The most estonishing feature of this line is however that there are four conductors on the pylon: three for the phase of the 110 kV-system, which are implemented as two bundle conductors and one neutral conductor, which is realized as single conductor. The reason for this arrangement results from the fact, that this line feeds the power from one 380 kV/110 kV-transformer on the area of Grossgartach Transnet Substation to Grossgartach Süwag Substation, where the grounding of the neutral conductor is realized over a coil.
As I know this is the only high-voltage three phase AC line with neutral conductor outside a switchyard area. Do other forumers know also such lines?

Tower 1 of Facility 1360. The double-bundle conductors are for the phases of the 110 kV-system it carries, the single conductor is for the neutral conductor
