った。In the above-mentioned conventional reinforced type lightning-resistant coil, the lightening of the inner frame 5 is performed by machining a groove having the same depth as the outer shape of the cotton winding 6 and fixing the groove with a plurality of outer frames 4. The surge prevents the deformation of the cotton winding 6 due to the electromagnetic force applied to the cotton winding 6, but the plurality of outer frames 4 cannot completely suppress the deformation of the cotton winding 6. In order to provide a structure that can withstand the electromagnetic force, the inner frame 5 and the outer frame 4 are further provided with a plurality of frames, so that there is a problem that the cost is high.
