Problems solved by technology

[0004] Generally, the traditional national defense high-speed data transmission cable, the inner conductor is made of stranded silver-plated copper conductor, the shield is braided with high-braided silver-plated round copper wire, and the insulation and use of polytetrafluoroethylene, polyfluoroethylene propylene and other materials, In order to meet the multi-channel transmission of data signals, twisted pairs or shielded twisted pairs are used. The following problems often occur during the use of such products: when the inner conductor is silver-plated copper and the cross-section is small, the DC resistance of the conductor increases, which

Abstract

The invention discloses an ultrahigh-speed data transmission cable and a manufacturing process thereof. The ultrahigh-speed data transmission cable comprises graphene silver-copper alloy inner conductors which are twisted concentrically, and a sheath-foam-sheath tetrafluoroethylene-hexafluoropropylene copolymer insulating layer wrapping the conductors, wherein the cable core employs a star-twist group structure, and is additionally provided with a filling material, a silver-plated copper-clad steel flat wire and a silver-plated copper-clad nickel round wire are woven outside the conductors, and the sheath is made of a cross-linked ethylene tetrafluoroethylene material. According to the technical method, the cable has the advantages of ultra-light property, high rate, high strength, high electromagnetic interference resistance and high-reliability and high-speed data transmission.

Description

technical field [0001] The invention relates to the technical field of product design and manufacturing process of an ultra-high-speed data transmission cable, in particular to an ultra-high-speed data transmission cable and its manufacturing process, which are applied to a cable with small outer diameter, light weight, high resistance to electromagnetic interference, and high speed , high reliability, high-speed signal data transmission suitable for space environment transmission, suitable for aerospace, aviation and other special environmental fields.
