The 67.8 metres tall tower 14 is the northern terminus of Kocher valley crossing of 380 kV-line Kupferzell-Stalldorf-Grafenrheinfeld. Originally 5 ropes above the conductor cables were installed at these crossing, which were the rope with the flight warning marker balls and two communication cables each hung up on a rope like a garland. In 2022 these communication cables were replaced by a single free-spun cable, so today only 2 ropes above the conductors exist today.

Anlage (German for "facility") 334 is the 110 kV-powerline branch from the 380 kV/110 kV-powerline Pulverdingen-Oberjettingen to Sindelfingen substation. It starts from two branch pylons southwest of Sindelfingen-Maichingen and runs from there straight to Sindelfingen substation. It enters Sindelfingen substation in a somewhat unusual way as its circuit on the lowest crossbar enters it directly from the tall Tower 10, while the circuits on the upper crossbar run over a further tower, carrying the number 11, whose height is between that of Tower 10 and the height of the portals of Sindelfingen substation.
Anlage 334 was built in 1971. Its upper circuits use double-bundled conductors and hang from the startpoint of the branch until Tower 10 on insulators for 220 kV. Interestingly the last section has single conductors and are installed on insulators for 110 kV. From 1971 to 1979 only one of the circuits on the upper crossbars was in use.
The circuit on the lowest crossbar was installed together with its crossbar in 1990. It uses in its whole length single conductors, which are mounted on insulators for 110 kV.

A closer view on Tower 11 of Anlage 334, which is used for the introduction of the circuits on the upper crossbars of Anlage 334 into the switchyard of Sindelfingen substation.

My picture https://www.hoogspanningsforum.com/down ... p?id=42895 shows the bases of the towers of the future branch from the 380 kV-line Philippsburg - Pulverdingen to Birkenfeld. Meanwhile these towers are completed, while the old Tower 116 of the line Philippsburg - Pulverdingen is already partly dismantled. The eastern of these towers (left on the second picture) has a height of 95.65 metres, while the other one measures 88.15 metres.

Tower 117 of powerline Philippsburg-Pulverdingen and a tower of the paralell-running traction power line Wiesental-Vaihingen east of the towers shown in my previous post. Note the moon "in" the tower of the traction power line!

The first towers of the future 380 kV-branch to Birkenfeld substation are still without conductors. They will not only carry 380 kV-circuits. Their lowest crossbar will be used for the 110 kV-line Mühlacker-Karlsruhe of the German railway company and replace the existing line.

The circuits of the 110 kV-powerline Kupferzell-Niederstretten share until Tower 63, which is situated south of Adolzhausen the towers of the 380 kV-line Kupferzell-Stallldorf-Grafenrheinfeld. After Tower 63, which has a height of 47.48 metres, both lines run on their own course.

Until 2022 the powerline Kupferzell-Stallldorf had 2 garland-like communication cables - one on the ground conductor and one on an auxiliary rope on the pinnacle just below it. Interestingly the 110 kV-branch to Niederstetten has still two communication cables - one like a garland on the ground conductor and a free-hanging one.

The powerline Kupferzell-Stalldorf-Grafenrheinfeld running northward after Tower 63. Until 2022 the ground conductor of these towers carried a garland-like communication cable. It is planned to install a further 380 kV-circuits on these towers in near future.
