PROBLEM TO BE SOLVED: To impart high flexibility and durability to a water-cooled cable, and also restrain reduction in conductivity and rise in the cost as the whole layer-stranded conductor of the water-cooled cable. SOLUTION: Copper-silver alloy wire material is employed as a strand forming the layer-stranded conductor in the water-cooled cable. Copper-silver wire material is employed as each strand which is located on the periphery of a primary stranded wire forming the conductor, and pure copper wire as each strand which is located in the center of the primary stranded wire. |
