The invention provides a stranding type carbon fiber composite material core aluminum round wire stranded wire. The stranded wire comprises multiple strands of stranded wires and at least one aluminum stranded wire layer, wherein the strands of stranded wires are stranded to form a wire core and are all carbon fiber composite material stranded wires; in addition, the cross section of each strand of the stranded wires is circular; the wire core is coated with the respective aluminum stranded wire layers in sequence; and the aluminum stranded wire layers are stranded. The wire core of the stranded wires provided by the invention is the wire core which is formed by stranding of the multiple strands of carbon fibre composite material stranded wires, equivalently, the wire core of the stranded wires is the carbon fiber composite material wire core; compared with the conventional wire, the wire with the carbon fibre composite material stranded wires has smaller sag at a high temperature, so that clear distance over the ground of the wire is ensured and potential safety hazards are reduced; and in addition, the stranded wires with the carbon fiber composite material wire core are high in mechanical characteristics and have the best sag and loading indexes in all heat-resistant wires, so that the stranded wires are suitable for large-span and important circuits.
