The invention relates to a special-shaped wire strand cable conductor and a production method of the special-shaped wire strand cable conductor and relates to a wire and cable special-shaped wire strand round conductor with the nominal cross section ranging from 25 mm<2> to 630 mm<2>. The cable conductor comprises a single round wire and special-shaped wires with all the strand layers designed in the tile-shaped structure according to the specifications of cables. The production method includes the steps that first, according to the designed special-shaped wire structure, the single round wire in the center is manufactured in a drawing mode through a drawbench, and then the special-shaped wires of various specifications of strand layer structures are manufactured on a water tank type or sliding type or fractional motor type drawbench in a drawing mode through a special-shaped high-speed wire drawing die; the round line in the center is placed on a payoff rack of a wire stranding machine, and all the stranding layer special-shaped wires are placed on a frame winch or fork winch and manufactured into the special-shaped wire strand cable conductor through stranding. The outer surface of the cable conductor is smooth and free of burrs, the gap between single wires is small, the filling coefficient is larger than 0.98, and the strand cable conductor is stable in structure. The production method is high in technology universality, and updating and upgrading of the products can be achieved in small and medium-sized enterprises through the technology.
