PURPOSE:To prevent the decrease in a current density and to decrease the partial heating and loss by providing a plurality of leads of an inner conductor and taking them out of the window in an outer conductor at a circulary shifted position on a cylinder-type conductor made of a sheet-shaped material. CONSTITUTION:Leads 4a and 4b which are the beginning of the winding of an inner conductor 1 are shifted in the circumferential direction by a length H1. Thus, the rate of reduction of a cross-sectional area by a window provided in an outer conductor 2 is decreased for each row. Leads 3a and 3b of the end of the winding of the outer conductor 2 are also shifted in the circumferential direction by a length H1, and extended to the position opposing the inner leads 4a and 4b. Thus, the leads are alternately arranged as +-+-. Therefore, the connecting conductors which connect the winding leads to bushings are arranged so that the positive and negative connecting conductors are sequentially alternated. In this constitution, the decrease in a current density can be prevented and partial heating can be eliminated. |
