Vibration self-constriction low-loss stable-phase coaxial cable

The invention provides a vibration self-contraction low-loss stable-phase coaxial cable and relates to the technical field of communication cables. The vibration self-constriction low-loss stable-phase coaxial cable comprises an inner conductor, a first vibration self-constriction intermediate insulating layer, an outer conductor and a vibration self-constriction outer sheath. The inner conductor, the first vibration self-constriction intermediate insulating layer, the outer conductor and the vibration self-constriction outer sheath are successively arranged from inside to outside. The outer conductor comprises an alloy belt layer, a second vibration self-constriction film layer and a metal wire mesh grid layer which are successively arranged from inside to outside. A vibration self-constriction function of a micro-nano material is applied to the low-loss stable-phase coaxial cable, so that the mechanical stability of the cable is improved, and the mechanical loose problem of a cable system caused by different expansion and contraction coefficients among the layers of the cable is fundamentally solved.
