摘要： PROBLEM TO BE SOLVED: To prevent the reduction of a critical current and make a superconductive current lead compact by arranging multiple units of a single tape-like oxide superconductive wire or a layered product on a cylindrical support member made of a low-heat conductivity material while the tape faces are made parallel with the peripheral direction of a cylindrical coordinate system. SOLUTION: Tape-like superconductive wire units 1 made of a sheath material of silver or a silver alloy at the silver cross sectional ratio of about 2-3 are fixed to an oxide superconductive while the tape faces are made parallel with the peripheral direction around a cylindrical support member 3. The main component of the self- magnetic field caused by the self-current is made parallel with the tape face, the vertical component is reduced, the reduction of a critical current value due to the self-magnetic field is decreased, and the self-magnetic field is not disturbed. The heat contraction coefficient of the material of the support member 3 when a current lead is cooled to the prescribed temperature from the room temperature is preferably set to -0.4% through -0.15% between the heat contraction coefficients of silver and superconductor. The essential strain of the superconductive wire is kept in the compressive direction, and the deterioration of the critical current value caused by thermal strain is prevented.

摘要： PURPOSE:To prevent generation of wrincles on an insulating tape, and to improve both mechanical strength and electric characteristics by a method wherein a superconducting wire composite conductor, having a rectangular cross section, is formed with a winding, and a piece of resin coated or impregnated elastic woven cloth is used as an interturn insulator. CONSTITUTION:A superconducting coil 1 has a superconducting wire composite conductor 5, having rectangular cross section, as a winding, and an interturn insulator 6 is arranged between the windings. An insulating tape, formed with a piece of resin-coated or resin impregnated woven cloth, is used as the material of the interturn insulator 6. By using the insulating tape having a high degree of elasticity as the interturn insulator 6 as above-mentioned, the insulating tape can be wound around the superconducting wire composite conductor 5 uniformly even when the winding, consisting of the superconducting wire composite conductor 5, has a sharp-angled rectangular cross section, and the generation of wrinkles can be prevented. As a result, the insulating tape can be arranged between windings in the prescribed designed dimensions, and high electric characteristics can be obtained. Also, mechanical strength can remarkably be improved.
