The utility model provides a composite festoon cable which comprises a power wire core and a control unit, a conductor I of the control unit is formed by stranding a steel wire reinforcing core and acopper wire, an insulating layer is arranged outside the conductor I of the control unit, and a cable hemp filling body is arranged in the center of a wire group of the control unit. An isolation layer is arranged outside the wire group of the control unit; an ethylene-propylene rubber insulator is arranged outside the conductor II of the power wire core; a central filling body is arranged in thecenter of a general wire core group of the cable, and a first braided reinforcing layer, an inner sheath, a second braided reinforcing layer and an outer sheath are sequentially arranged outside the general wire core group. The research and development of the product solve the problems that large hoisting machines such as gantry cranes and travelling cranes have the requirements for frequent movement and use, low-voltage power and composite cable control are achieved, and the problem of core breakage of a control unit and the problem of flexibility of the cable are solved.
