The invention aims to design a special cable for a concrete structure of a graph-digital-analog integrated grid data management platform. The special cable is simple in structure, convenient in maintenance, and high in safety performance. Therefore, in the invention, the special cable of the graph-digital-analog integrated grid data management platform includes a wire cover; an inner pat of the wire cover is provided with an insulating protective layer; the cable cover is internally penetrated by six to eight secondary functional wires; the secondary function wires are inserted by wire cores; each wire core of each secondary function wire is provided with a same wire core diameter and function; the wire cover is internally provided with a plurality of deconcentrators; the wire cores are connected to a plurality of joints through the deconcentrators; each joint is connected with wire cores in different secondary function wires; and the wire cores of the secondary function wire which are connected on each joint are arranged in different sequences. According to the invention, a plurality of wire cores are arranged differently, so that each joint can be a special joint; and the joint can only be matched with a special interface which is arranged on a corresponding device, and cannot be freely applied to other situations.
