Hollow expanded-diameter aluminum steel wire

The utility model relates to the technical field of power cables, in particular to a hollow expanded-diameter aluminum steel wire. The cable comprises an embossed aluminum pipe for providing radial support, an inner wire layer and an outer wire layer are concentrically stranded outside the embossed aluminum pipe, the outer wire layer is stranded outside the inner wire layer, the stranding direction of the outer wire layer is opposite to that of the inner wire layer, and the inner wire layer and the outer wire layer form a circular structure after being stranded; the inner conductor layer is composed of a certain number of aluminum single wires with circular sections and a plurality of galvanized steel wires with circular sections, the galvanized steel wires are evenly distributed among thealuminum single wires at intervals, the diameter of the galvanized steel wires is the same as that of the aluminum single wires, and the aluminum single wires and the galvanized steel wires are distributed in a single-layer
