The invention is based on the problem of creating a single-pole or multi-pole electrical power transmission device having pairs of sliding contacts which are as simple to produce as possible. The single-pole or multi-pole electrical power transmission device, especially for use on a cable drum, has at least one pair of sliding contacts (23, 21 and 28, 27 respectively). Each pair of contact discs (23, 21 and 28, 27 respectively) has a first contact disc (23, 28) which is closed in the form of an annulus and is flat even in the axially unloaded state. Each pair of contact discs (23, 21 and 28, 27 respectively) also includes a second contact disc (21, 27), which is likewise closed in the form of an annulus and has a projection which extends over a circumferential angle range ( alpha ) and over the entire radial width (b) of the circular ring disc (21, 27) continuously, in the form of a bulge (24, 32). The bulge (24, 32) can spring in parallel (in the x direction) to the rotation axis of each pair of contact discs (23, 21 and 28, 27 respectively). <IMAGE>
