Medium-voltage power cable

The utility model discloses a medium-voltage power cable. The power cable comprises conductors, insulating layers, a packing material, a water blocking layer, an outer sheath, shielding layers, a flame retardant layer, a water retaining layer and an armor layer, wherein the conductors are wrapped in the insulating layers; the insulating layers are wrapped in the shielding layers; the conductors, the insulating layers and the shielding layers form wire cores; a plurality of wire cores are stranded to form a cable core; the cable core is wrapped in the flame retardant layer; the packing material is arranged between the adjacent wire cores; and the water blocking layer, the water retaining layer, the armor layer and the outer sheath are sequentially arranged outside the flame retardant layer. The medium-voltage power cable has flame retardant and waterproof functions, and can meet the use requirement that the flame retardant and waterproof functions are needed when the medium-voltage power cable is applied to pi
