The invention relates to a cable air supply pipeline, and belongs to the technical field of bridge cables. Comprising a corrugated pipe and a steel wire, a continuous thread structure is formed on the pipe wall of the corrugated pipe, and the steel wire is connected with the corrugated pipe and the steel wire in a threaded mode. The steel wire is wound on the outer wall of the corrugated pipe along the thread structure; the connector comprises a universal connector and an air outlet connector, and the universal connector and the air outlet connector are arranged in a spaced mode. The dehumidification device serves as a dehumidification component of the cable and is arranged in the middle of a steel wire bundle of the cable, and ventilation and dehumidification are conducted on the interior of the cable through the air supply pipeline. The air supply pipes have good flexibility, the coiling requirement is met, and the multiple sections of air supply pipes are alternately connected through the air outlet connec
