Summary:PROBLEM TO BE SOLVED: To provide a winding for a stationary induction electric device in which serial electrostatic capacitance is further adjusted for improved insulation performance, with the winding having resistance against a steep surge voltage, and miniaturization being possible.SOLUTION: Strand conductors 101A and 101B that are applied with insulation coats 102A and 102B are wound to form disc coil units 100A and 100B. The disc coil units 100A and 100B are interpenetrated so that a strand conductor of different number of winding turns is positioned between turns while winding of the strand conductors 101A and 101B progresses, thus constituting a winding for a stationary induction electric device by an interleave method. Relating to the strand conductors 101A and 101B in which the disc coil units 100A and 100B are interpenetrated, one insulation coat 102A is formed of craft paper while the other insulation coat 102B is formed of insulation paper which has a higher dielectricity like an amine-added paper with an excellent heat-resistance insulation characteristic.
