Summary:The invention relates to a cable reinforcing mandrel for a power transmission cable. The cable reinforcing mandrel comprises an inner electroconductive layer and an outer insulating layer, and is characterized in that a winding layer is arranged between the inner electroconductive layer and the outer insulating layer. According to the technical scheme adopted in the invention, the winding layer is added, therefore, the cable reinforcing mandrel for the power transmission cable has the advantages of increased resistance to destructiveness in a radial direction, and simultaneously enhanced flattening, bending and other mechanical properties.
