NOVELTY - This utility model relates to wire processing field, specifically to a method of ultra-fine coaxial line shielding composite. Said technical purpose of this utility model is realized by the following technical solution: a micro coaxial shielding composite cable, comprising a conductor made of metal material composed of a central conductor layer and the insulating layer of the outside of the central conductor layer, graphene shield layer by graphene material is set on the outside of the insulating layer. The purpose of the utility model is to provide a fine coaxial line shielding composite, adopts the new design of the shielding layer, which not only increases the shielding effect, but also further reduces the wire diameter and the weight of the whole cable.
