Until 2016, there was in Dazhou a really unique powerline
It started at a quite tall termination tower

which was followed by a huge tubular tower for crossing a highrise building

which was followed by a powerline tower on a highrise building (coordinates: 31°11'28"N 107°30'43"E)

Unfortunately, I have no details on the used voltages and the construction year of the powerline and the highrise building, on which the tower stood.
