Spiral micro-groove type air-blowing micro-cable, and manufacturing equipment and manufacturing method

The invention discloses a spiral micro-groove type air-blowing micro-cable, and manufacturing equipment and a manufacturing method. The air-blowing micro-cable comprises a cable core and an outer protective layer coating the cable core, and the outer wall of the outer protective layer is provided with a spiral groove used for guiding air to increase air-blowing pushing force. According to the spiral micro-groove type air-blowing micro-cable, the manufacturing equipment and the manufacturing method, the spiral groove is formed in the outer wall of the outer protective layer of the air-blowing micro-cable, so that under the condition that the original performance of the air-blowing micro-cable is not changed, high-pressure airflow can uniformly wrap the air-blowing micro-cable during layingto make the air-blowing micro-cable always kept in the center of a pipeline, the friction between the air-blowing micro-cable and the pipe wall in the conveying process is reduced, the air-blowing resistance is reduced, and t
