PROBLEM TO BE SOLVED: To efficiently cool without using a circulating cooling medium by arranging a redox reaction material for absorbing the heat in the reduction reaction adjacent to a conductor provided with an insulating material, a shield layer and a corrosion-proof layer in order in the periphery thereof. SOLUTION: A hollow pipe 1 made of the redox reaction material of Fe, Cr, Co, Cu, Ag, or Mn can be provided at the center of a conductor 3 and between an insulating material 4, and cross section thereof is increased by forming folds in the inner wall thereof. The redox reaction material oxidized when the use of power is small is deoxidized when the heat load is applied by the flow of the heat and the reducing agent so as to absorb the heat, and temperature is lowered so as to increase the power feeding capacity at the peak time. The redox reaction material is coated on raw wires of the twisted wire as a structural member of the conductor 3, and twisted with the raw wires, and combined with an oxygen supplying spiral tube for flowing the oxygen from a clearance. A material to be vaporized at 30-105 deg.C so as to absorb the heat can be closely packed between the raw wires of the twisted wire or filled in the hollow pipe inside of the twisted wire. |
