A conductor line for supplying an electric load movable on the conductor line in the longitudinal direction of the conductor line, includes at least one conductor strand which runs in the longitudinal direction and has an electrically conductive profiled conductor section for contacting a sliding contact of a current collector of the load and at least one elongated slotted waveguide, which runs in the longitudinal direction, with a longitudinal slot for receiving an antenna which can be moved together with the load. A related current collector and a conductor line system are also provided. The aim is to allow a compact and material-saving design with good fault-tolerant transmission. This is achieved by a conductor line in which the longitudinal slot is tilted by an angle which does not equal 90° about the longitudinal direction with respect to a movement plane on which the current collector can be moved, by a current collector in which the antenna or a part thereof is completely or partly tilted by an angle which also does not equal 90° about the longitudinal direction with respect to the movement plane, and by a conductor line system including such a conductor line and current collector.
