View on the towers of Powerline Kupferzell-Stalldorf-Grafenrheinfeld south of Adolzhausen toward Kupferzell, where the pylons are shared by the 110 kV-powerline Kupferzell-Niederstetten on the lowest and the 380 kV-powerline Kupferzell-Stalldorf-Grafenrheinfeld on the upmost crossbars. You can see on the pinnacles of these towers a small beam between the top crossbar and the pinnacle. It was used until 2022 for the installation of an auxiliary rope, which carried - as the ground conductor - a garland-like communication cable.

Nice towers and winter landscape.
I also notice to climb this tower, the linemen can avoid the 110 kV conductors by transferring to a climbing rail at the center of the tower. When they are passed the lower cross arm, they can go back to the stepping bolts at the main leg again :grin: .

This device was not installed when the pylons were built. An older picture of the line on https://commons.wikimedia.org/wiki/File ... usen_1.jpg does not show it! I believe it was installed at the same time when the communication cables on the pinnacle were replaced.

My last posts showed various communication cables installtions along high voltage power lines. In this posting, the communication cable, which is installed on the pylons of the 110 kV-powerline Brendlorenzen-Kleinbardorf, is shown. It is wrapped around the conductor rope, which is attached to the inner suspension point of the northern side of the lowest crossbar and is therefore installed on high voltage potential!

The 380 kV-powerline Grafenrheinfeld-Stalldorf-Kupferzell and the 380 kV-powerline Grafenrheinfeld-Höpfingen are between Grafenrheinfeld and Rittershausen installed on the same pylons. West of Ritttershausen at the such called "Mast X" the lines split. The right branch runs to Höpfingen, the left branch over Stalldorf to Kupferzell. Until 2015 the branch to Kupferzell was equipped with a garland-like communication cable on the ground conductor, which ended at Mast X.
Originally the branch to Höpfingen belonged to "Badenwerk" and that to Kupferzell to "EVS", while the double-circuit line was property of "Bayernwerk". Today the double-circuit line before the branch is property of "Tennet" while both branches are owned by "Transnet BW".

A closer look to the such called "Mast X", where the two 380 kV circuits from Grafenrheinfeld split into the line to Kupferzell (leaving the picture on the right) and to Höpfingen (leaving the picture on the left). The branch to Kupferzell was until 2015 equipped with a communication cable, which was fixed like a garland on the ground conductor.

The last towers of the 380 kV-line from Grafenrheinfeld before the branching. The last four towers of this line before the branch tower carried until 2015 a communication cable on the horizontal joist of the pinnacle.

On December 27th, 2023 I was again at the startpoint of the future branch from the 380 kV-line Philippsburg - Pulverdingen to Birkenfeld. Meanwhile the line from Philippsburg to Pulverdingen is working again. The eastern of these towers (left on the first picture, right on the second and third picture) has a height of 95.65 metres, while the other one measures 88.15 metres. On the second and third picture you can see a red-white painted radio mast in the background; it is the 273 metres tall mast of Mühlacker transmitter.
