The leaky coaxial cable includes: an inner conductor, an insulating layer, an outer conductor and an outer sheath. In order to reduce the dielectric constant of the insulating layer, reduce the attenuation of the insulating layer, optimize the good attenuation performance of the leaky coaxial cable, and ensure the electrical performance of the leaky coaxial cable, the insulating layer will be set in a spiral shape. Therefore, it is necessary to provide a processing device for the spiral insulating layer of the leaky coaxial cable.
