Wait, that doesn't sound right. It's a bit hard to tell with Google translate. But from what I see on the wikipedia article (https://de.wikipedia.org/wiki/Verdrillmast https://de.wikipedia.org/wiki/Verdrillmast) Germany is doing exactly the same thing as is done in the US - the US does not twist lines in midair. Only at poles. What do you mean by "moving parts"? The US lines don't have any parts that move more than slightly, which EU lines do as well (they have too: the lines themselves expand and contract, and move in the wind, so the insulators have to have flexibility).
