The famous 146.5 metres tall Berlin Radio Tower (German: Berliner Funkturm) was in its first years also a "pylon" (or how would you call a tower, at which an electrical wire ends) as it carried from its inauguration in 1926 until 1935 a T-antenna for mediumwave broadcasting, whose other end was fixed on a 80 metres tall guyed mast, which was dismantled after the destruction of the transmitter in 1935.
What makes this tower unique is the fact, that it is the only observation tower in the world, which stands on electrical insulators, which were however never used as one detected, that if one would insulate the tower against ground, visitors may get an electric shock, when they enter the tower, so it was decided to ground it over the elevator shaft.
Unfortunately the tower is at the date, when the picture was made (July 9th, 2023) under renovation and so I was not able to photograph the insulators, which are still in place.
Berlin Radio Tower is, when open, a wonderful touristic destination with a panorama lift, an open-air observation deck and a restaurant in the middle. Do not miss it, when you are in Berlin and it is open for visitors!
The full history of this tower is decribed on https://de.wikipedia.org/wiki/Berliner_Funkturm (in German).

In the eastern parts of Berlin, which formed before 1990, the former capital of GDR, you can find more overhead electricity lines. The following picture shows pylons of the 220 kV-line Marzahn-Wuhlheide with the tallest chimney of Berlin, the 169 metres tall chimney of Marzahn district heating plant in the background.

Nice pictures from Berlin! That chimney mast in your previous post is a really unique one. Never seen something like that :s .

Neuenhagen substation is the most important hub for the power supply of the eastern parts of Berlin. It went in service in 1957 as 220 kV/110 kV-substation with two 220 kV-lines to Trattendorf power station and is today a 380 kV/220 kV/110 kV-substation.

Neuenhagen substation has also a 99 metres tall radio relay tower.

Nice images from Berlin. I have seen a picture of the chimney pylon somewhere before. I also see that I have to make some adjustments to the Neuenhagen substation on the map.

A 110 kV-tower with 4 circuits in Berlin-Kaulsdorf. It is the classical GDR-type, however with 2 crossbars.

Powerline towers north of Neuenhagen substation with nocturnal clouds in the background. The illumination of the conductors of the line in the foreground however comes from street lamps in a nearby industrial area.

North of Königs Wusterhausen, there is one of the oldest transmission sites in Germany, established in 1916. From 1925 until 1972 it consisted of a 243 metres tall lattice tower, 6 guyed masts with a height of 210 metres, 5 guyed masts with a height of 150 metres and 2 guyed masts with a height of 100 metres between which wires as antenna were spun. On November 13th, 1972 storm "Quimburga" destroyed the central tower and as result of decreasing demand for longwave transmission antennas most of the other masts were dismantled.
Of the large masts only one 210 metres tall guyed masts survived, which carried until the turn of the century wire antennas for longwave broadcasting. However in 1994 a 67 metres tall tower for cellphone and low-power FM-broadcasting was built.
The oldest existing towers of the facility are however the three 29 metres tall counter towers, which were built in 1913 and originally used as pylons for the antenna running from the transmitter building to a horizontal wire spun between two large guyed masts, which exist not any more today. One of these counter towers is unused, while the two others carry an antenna looking like a powerline - a such called T-antenna - which is used for occasional transmissions on 810 kHz under the name "Welle 370".

The landmark of Königs Wusterhausen transmitter , the 210 metres tall radio mast built in 1925. Originally, there were 6 such masts arranged in a circle around a 243 metres tall free-standing lattice tower. Surely a great sight!

Vandaag ben ik nog even naar Bad Bentheim gereden en heb ik op de terugweg enkele masten van het 110kV enkelcircuits steeklijntje naar Bentheim gefotografeerd.

Als je bij Oldenzaal via de snelweg de grens overgaat komt het steeklijntje na een paar kilometer al in zicht waarbij al snel de scherpe hoek van mast 13, die vlakbij de snelweg staat, opvalt. De mast staat bij een viaduct maar is desondanks toch nog lastig te fotograferen.

Vanaf het viaduct over de A30 en de A30 zelf is wel het verdere verloop richting Pkt. Quendorf te volgen waar het enkelcircuits steeklijntje aftakt van de 110kV verbinding tussen Nordhorn en Schüttorf. Het blijft een leuke herkenbare lijn als je vanaf De Lutte via de autosnelweg verder Duitsland in rijdt.
