PROBLEM TO BE SOLVED: To provide a solid cable with a conductor to be hardly twisted. SOLUTION: This solid cable 1 includes the conductor 10 of multilayer structure constituted by stranding concentrically a plurality of irregular strands 12 having a sector-shaped cross section, on an outer face of the center strand 11 having a circular cross section, and an insulating layer 21 constituted by winding an insulating material on an outer face of the conductor 10. A thickness of the irregular strand constituting the outermost layer is thinner than a thickness of the irregular strand constituting the layer in a just under side of the outermost layer, in the conductor 10. A pitch magnification (set pitch/outer diameter of corresponding layer) constituting the outermost layer is smaller than a pitch magnification of the irregular strand constituting the layer in the just under side of the outermost layer. A rotation angle of the outermost layer is made low, by this constitution, to hardly twist the conductor. COPYRIGHT: (C)2010,JPO&INPIT |
