▎ 摘　　要

NOVELTY - The cable has a cable inner conductor (1) comprising a carbon fiber core coated with a graphene conductive film composite conductor. An insulating layer (2) is mounted outside the cable inner conductor. A graphene conductive film outer conductor (3) and a sheath layer (4) are mounted outside the insulating layer. The insulating layer is a microporous PTFE belt, and is sintered at a high temperature. USE - Non-metallic coaxial cable such as radio frequency (RF) coaxial cable used for signal transmission in fields of defense industry, medical equipment and special detection equipment. ADVANTAGE - The manufactured cable has wide application temperature range, no metal material. The cable is lightweight, safe and has long-service life. Environmental protection is ensured. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a manufacturing method of non-metallic coaxial cable. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view of the non-metallic coaxial cable. Cable inner conductor (1) Insulating layer (2) Graphene conductive film outer conductor (3) Sheath layer (4)
