Abstract
The invention discloses a multi-core cable which comprises a plurality of functional core wires, an outer sheath and non-metallic flexible core wires, wherein, the outer sheath is used for wrapping the functional core wires; the non-metallic flexible core wires are arranged in the outer sheath for preventing the condition that the multi-core cable is ruptured due to excessive distortion so as to lead the plastic deformation of the non-metallic flexible core wires to be less than that of the functional core wires; and the functional core wires comprise conductor cores and a core wire insulator comprising the conductor cores. In the invention, as the plastic deformation of the non-metallic flexible core wires arranged in the multi-core cable is less than that of a core conductor, the non-metallic flexible core wires can share more tensile force during the repeated bending and stretching process, thus reducing the load of the conductor cores and improving the anti-breaking property of the multi-core cable. The non-metallic flexible core wires further strengthen the external force undertaken thereby under the action of restoring force, thus reducing the plastic deformation of the multi-core cable and avoiding the functional core wires from being broken owing to excessive local plastic deformation.
