Salt-fog-resistant environment aluminum alloy power cable

The utility model relates to the technical field of power cables, in particular to a salt-fog-resistant environment aluminum alloy power cable, which comprises a stranded conductor adopting a four-layer stranded structure. The polyester belt wrapping layer is wrapped on the outer wall of the stranded conductor; the insulating layer is extruded on the outer wall of the polyester tape wrapping layer; the outer sheath is extruded on the outer wall of the insulating layer; and the water blocking structure is arranged among the four layers of stranded structures. The stranded conductor adopts a same-direction stranding mode, and the pitch of the outer layer is smaller than that of the inner layer, so that the formed stranded conductor has good bending performance, the pressing effect of the outer layer on the inner layer is strong, gaps between the conductors are reduced, and the water blocking ropes arranged between the conductors are matched, so that the water blocking effect is good. And a closed region with th
