The two copper conductors in each copper conductor pair are arranged in a parallel manner. Each copper conductor is externally covered with an insulated foaming layer which is used for insulation and provided with a plurality of holes. A piece of non-woven cloth is covered on the copper conductor pair wrapped by a first single-sided aluminum foil. The five copper conductor pairs respectively wrapped with first polyester tapes are twisted on the outer side of the non-woven cloth. An inner PVC sheath layer is covered on the outer surface of a second single-sided aluminum foil. An outer PVC sheath layer is covered on the outer side of the inner PVC sheath layer. A shielding woven belt woven by tin-coated copper wires is located between the inner PVC sheath layer and the outer PVC sheath layer. The twisting-resistant high-speed data cable is capable of reducing the influences of high-frequency electromagnetic radiation and capacitance coupling on data communication, increasing the stretch-proofing and twisting-resistant capacities of the cable in the utilization process, prolonging the service life of the cable, and having very good practical values and popularization values.
