Medium-voltage dynamic cable and manufacturing method

The invention discloses a medium-voltage dynamic cable and a manufacturing method, the medium-voltage dynamic cable comprises multiple groups of wire core bodies, each wire core body comprises a new conductor, and the outer side of each new conductor is sequentially wrapped with a new semi-conductive conductor shielding layer, a new insulating layer, an inner semi-conductive insulating shielding layer, a metal shielding layer and an outer semi-conductive insulating shielding layer; a new inner sheath, a new braided reinforcing layer and a new outer sheath are sequentially wrapped outside the plurality of groups of wire cores, polyethylene octylene wires are arranged in the new inner sheath, and new center filling is arranged among the plurality of groups of wire cores; the new conductor is formed by stranding bare soft copper wires into strands and then stranding the strands; and the new semi-conductive conductor shielding layer, the new insulating layer and the inner semi-conductive insulating shielding laye
