Disclosed is a power conducting device, especially for long displacement paths, comprising at least one power conducting unit (1) that is composed of members which are hingedly interconnected via pins (3) extending perpendicular to the longitudinal direction of the power conducting unit (1). A first end of the power conducting unit (1) can be fixed in a stationary manner while the second end (5) is movable at least in the longitudinal direction. The power conducting unit (1) forms a top strand (8) and a bottom strand (7) between which at least one supporting carriage (9) is disposed which can be moved fore and aft in the longitudinal direction of the power conducting unit. Said supporting carriage is provided with a base (10) that is joined to a drawback device (12) which is formed at least in part by at least one curved conduit (13) such that the power conducting unit (1) is guided within the curved section (6).
