The invention relates to the technical field of charging cables, and discloses a cable and a manufacturing method thereof, the cable comprises a cable core, an aramid fiber braid layer and a sheath layer, a plurality of conductor monofilaments and an aramid fiber bundle are twisted into a plied yarn, and the tensile strength is provided; a plurality of strands are reversely stranded to form a semi-finished conductor, so that repeated bending deformation is avoided, and the flexibility is ensured; the copper wire braided layer is braided on the outer surface of the semi-finished conductor to assist the cable in resisting deformation, the copper wire braided layer and the semi-finished conductor can transmit current, the transmission efficiency is improved, and the economic value is high; an insulating layer is extruded on the outer surface to form a conductor, so that the safety is improved; the plurality of conductors and the filling member form the cable core, the appearance is round, the structure is stable, and the service life is prolonged. Finally, the outer surface of the cable core is sequentially braided and wrapped with the aramid braided layer and the sheath layer, the tensile strength of the cable is further improved, and wear resistance is improved; the cost is reasonable, the low-temperature use requirement of the intelligent movable charging robot is met, and good winding and bending performance and electrical performance are achieved.
