Production method for light low-attenuation wrinkled coaxial cable

Abstract

The invention relates to a cable processing technology, in particular to a production method for a light low-attenuation wrinkled coaxial cable. The technical scheme is that the production method for the light low-attenuation wrinkled coaxial cable sequentially comprises the following steps: (1) preparing an inner conductor; (2) wrapping an insulator, first enabling the inner conductor to enter an inner thin layer extruder to enable an inner thin layer to be formed outside the inner conductor; enabling the inner conductor where the inner thin layer is wrapped to enter a foaming insulating layer extruder to form an insulating layer; and forming an outer thin layer outside the foaming insulating layer through an outer thin layer extruder; (3) preparing an outer conductor; and (4) wrapping a sheath, and using a plastic extruder to enable a sheath material to be wrapped outside the outer conductor to form the sheath. The wrinkled coaxial cable prepared in the method has the advantages of being low in attenuation, uniform in impedance and large in return loss.
