<p>PROBLEM TO BE SOLVED: To prevent temperature rise of a cable by effectively cooling inside layers of the cable left as wound around a cable reel when the cable is energized while a part thereof is left around the cable reel. SOLUTION: A spiral groove 13a with a spiral pitch larger than the cable diameter is provided on the outer periphery of a body 13 of the cable reel 12. The cable 1 is wound around the body 13, along the spiral groove 13a, with the spiral pitch to provide an interval H between adjoining parts of the cable 1. As for the outer layers, the cable 1 is also spirally wound with the spiral pitch to provide an interval H between adjoining parts of the cable 1. Thus, by winding the cable 1 around the cable reel 12 in a manner that multiple layers and rows are formed, a cooling water passage 21 connecting the cable layers with one another can be formed.</p> |
