PURPOSE:To prevent the damage of a conductor or an insulating connecting tube by composing to pass coolant in parallel in the holes of the conductors, and reducing pressure loss of the coolant in the coil section, thereby reducing the pressure of the coolant. CONSTITUTION:Strands 1a, 1b formed with coating insulators 13 are aligned laterally at the outside of conductors 12 formed with holes 11 for longitudinally passing coolant to be wound in a coil shape. The ends of the strands 1a, 1b are exfoliated at the insulators 13 to expose the conductors 12, hollow bases 20a, 20b are respectively welded to the ends of the strands 1a-1, 1b-12, terminals 21a, 21b are respectively mounted at the bases 20a, 20b, and connected with insulating connecting hollow tubes 22a, 22b. Coolant is supplied through the tubes 22a, 22b to the strands 1a, 1b and exhausted from the tube 22c. Thus, the pressure loss of the coolant decreases in the coil section to circulate the coolant by a low pressure pump, thereby reducing the possibility of damage of the conductors and the connecting tubes. |
