Ultrahigh-speed data transmission cable and manufacturing process thereof

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.

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 affects the transmission rate. , At the same time, the strength of the conductor is not enough, and it is easy to break

In order to meet the technical requirements of the characteristic impedance of the data cable, because the outer diameter of the insulation of the product cannot be effectively reduced, the outer diameter of the twisted group is greatly increased, which ultimately affects the weight and outer diameter of the product. The outer conductor is a silver-plated round copper braid material, which is heavy

The overall product cannot meet the design requirements for high-speed transmission, weight reduction, strength, and high reliability
