The invention relates to a cable for a power transmission tower. The power transmission tower comprises a tower body and a power transmission assembly arranged on the tower body. The cable is a milliken conductor connected with the power transmission assembly. Multiple layers of copper wires arranged in a round shape are stranded and pressed to form the milliken conductor in a round structure. According to the cable for the power transmission tower provided by the invention, skin effects of the conductor are reduced, and the problem that insulating paper of the cable conductor is likely to break can be solved.
