Yeah, all you could do with that one is line_clamp=mixed.  The down/up/down
situation you could maybe handle as
line_clamp=suspension;pin;suspension.

Insulators are a particular practical mean to do so especially for power

That's true.  Insulated cable, so the attachment isn't an insulator.

The main point is to remove power dedicated values from tower:type.

Maybe.  Or maybe you need different terminology.  How about
"line_attachment" rather than line_clamp?
