sure, but you can't turn the actual wire itself indefinitely or it will shear eventually

You can just use a slip ring[1] at one or both ends (along with a whole bunch of axial thrust bearings, I imagine).

There are some neat (and very non-RoHS) slip ring implementations that use a series of liquid mercury filled channels to sidestep the brush wear issue, but I don't know that would be useful here, based on rotation speeds.
