Abstract

An arrangement for distributing a cable assemblage between a stationary part and a part which is arranged for limited rotation relative to the stationary part, the cable assemblage comprising at least one power cable and at least one signal transmission cable. The arrangement includes a centrally located tubular element mounted on the stationary part and a housing which surrounds the tubular element and which is connected to the rotatable part. The signal transmission cable extends axially through the tubular element and is folded or deflected through about 90.degree., and extends out through an opening provided in the element and is then loosely wound helically for a number of turns around the outer surface of the tubular element. The cable then extends out through an opening in the surrounding housing and is again folded or deflected through 90.degree., so as to extend substantially axially along the outer surface of the housing. The arrangement also includes a co-axially arranged power-cable winding device. The winding device is arranged to rotate synchronously with the rotatable element. The power cable extends through a sleeve or loom which is fastened to the stationary part and to the winding device. The power cable extends through an opening located in the periphery of the winding device, and is folded or deflected through about 90.degree., so as to extend axially along the outer surface of the housing, parallel with the signal transmission cable.
