Are brushes effective?

Getting back to the OP's original question, there is another way besides "slip rings". Slip rings are probably more practical in most situations. This is difficult to describe without pictures, but I'll give it a go.
Have a hollow central shaft that passes through a plate with a bearing. The plate is at one end of the shaft and the shaft is normal to the plate. (like a wheel on the end of car axle). A jacketted cable is passed through and clamped to the shaft, bent in a "U", and fastened to the plate. You can then rotate the plate on the shaft without twisting the cable.
