Abstract
A superconducting solenoid designed to improve working efficiency, heat resistance and electrical insulation of the solenoid to a practical extent. The superconducting solenoid comprises a winding frame, wires formed of filamentary conductors having superconductivity and wound around the winding frame, an insulator formed of alumina fiber material and covering each of the wires for providing electrical insulation, and a resinous material impregnated in between turns of the wires so as to provide a supporting structure. The insulator formed of alumina fiber material is in the form of a sheet, a mat or a yarn.
