PURPOSE:To enhance hardness, and to obtain a superconductive coil not to generate deterioration even when the coil is used for a long period by a method wherein when tube type electrically insulating materials are to be fitted on a slender superconductor interposing an interval between them to enhance cooling performance thereof, the insulating materials thereof are formed of a glass epoxy laminate having high Young's modulus. CONSTITUTION:Tube type electrically insulating materials 3a are fitted on a slender superconductor 2 interposing the prescribed interval between them to form a wire for superconducting coil. At this construction, a laminate of large Young's modulus such as glass epoxy, etc. is used for the insulating materials 3a, and made to surround the superconductor 2 fastening the conductor to some extent. At this time, when the superconductor 2 is not a round shape but is a square shape, the section of the insulating material 3a is formed also in a square shape conforming thereto. Accordingly, hardness of the winding is enlarged, and the coil is stabilized. |
