On http://www.hoogspanningsforum.com/viewt ... &start=860 , one can see some pictures of powerlines under construction north of Grossgartach substation west of Heilbronn. Meanwhile some changes occurred also there, as the conductors on the new line with 6 conductors were installed meanwhile, while the three missing conductors on the other line are still missing.
Interestingly the two circuits of the new line are still not in use.

Southwest of Marbach am Neckar one can find in the powerline Hoheneck-Wendlingen two branch pylons with follow each other. The branch on the right runs to Marbach power plant and is operated with 220 kV, while the branch at the left runs toward Neckarwestheim and toward Stuttgart-Mühlhausen. It is the newest pylon on the picture as it was realized when the voltage of the circuits of this line were changed from 220 kV to 380 kV,
The powerline branch to Marbach power plant originally started at the pylon, which carries as well suspension and strainer inulators. It is part of the powerline Hoheneck-Dellmensingen.

The branch to Marbach power plant. It consists just of 4 pylons. The last two pylons of the branch carry on its lowest crossbar the circuits of the 110 kV-line Marbach-Winnenden, which run south of Marbach on pylons with two crossbar before it gets northeast of Poppenweiler a part of the powerline Hoheneck-Winnenden.

The branch to Marbach power plant from an other point of view. Note the communication cable, which hangs like a garland on its ground conductor

The branch pylon of the powerline Hoheneck-Wendlingen, where the powerline to Marbach power plant starts and which carries the designation "Anlage 326, Mast 9", at the left of the picture and the double branch pylon "Anlage 326, Mast 10A" at the right of the picture.

The double-branch pylon "Anlage 326, Mast 10A". It carries on its two upmost crossbars the conductors of the line Hoheneck-Wendlingen and on the third upmost crossbar the conductors of the line Hoheneck-Winnenden.
On the lowest crossbars of this tower, which run in right-angle to the upper mentioned circuits the conductors of the 380 kV-line Neckarwestheim -Mühlhausen and the conductors of the 110 kV single-phase AC line Neckarwestheim Switching Station -Zazenhausen of the German Railway Company. Later line is together with the single-phase AC line Neckarwestheim Switching Station - Neckarwestheim Nuclear Power Plant the only single-phase AC line with quadruple conductors.
Originally, the power lines Neckarwestheim-Mühlhausen and Hoheneck-Wendlingen crossed each other without using a tower at this site. There was also no kind of interconnection.
When the voltage of the line Neckarwestheim-Mühlhausen was changed from 220 kV to 380 kV an interconnection between both lines were realized by the shown tower.
While the line Neckarwestheim-Mühlhausen had in earlier days two 220 kV-circuits, today only the section Neckarwestheim-Anlage 326, Mast 10A has two three-phase AC circuits, which are operated with 380 kV.
The section Anlage 326, Mast 10A carries beside the both circuits of the 110 kV-single phase AC line of the German Railway Company only one three-phase AC circuit for 380 kV.

The powerline Neckarwestheim-Mühlhausen north of the tower shown on the last posting. The lowest crossbar carries the circuits of the 110 kV single-phase AC line Neckarwestheim Switching Station-Zazenhausen, while the others carry the 380 kV-circuits of the powerline Neckarwestheim-Mühlhausen and Neckarwestheim-Endersbach. The circuit of later line uses between the branch tower ob the last picture and Endersbach the towers of the line Hoheneck-Wendlingen.

Concerning the construction of the branch from the powerline Philippsburg-Pulverdingen I can offer you a picture of the base of a tower at Mühlacker-Enzberg, where the branch will start.
The tower will have a height of 95 metres as it is used for overcrossing a 110 kV-line of the German railway company with 3 crossbars.
