PURPOSE:To facilitate assembly, repairing, and replacing operations of a winding; besides, to improve insulating performance and eliminate the possibility of breakage of the winding by tightening a low-tension winding with bands through supporting insulators, thereby fixing it with the supporting insulators, an insulating cylinder of a high-tension winding, and supporting structures. CONSTITUTION:Supporting insulators 15 which are circumferentially divided are applied to the outer circumference of a low-tension winding 4 and is tightened by bands 16, material of which is, for example, made of glass-fiber. After forming an insulating cylinder having its inner diameter corresponding to a winding dimension of the low- tension winding, circumferential grooves to be used for mounting the bands are provided at a plurality of axial places; besides, axial grooves to be used for inserting supporting structures 17 are provided at a plurality of circumferential places and after that, the supporting insulators 15 are divided and constructed at the circumference plane of the above insulating cylinder. After the supporting insulators 15 are fastened and fixed to the low-tension winding 4 with the bands 16, its winding 14 is inserted into the high-tension winding 5 and then, both windings 4 and 5 are integrated into one by inserting the supporting structures 17 after performing the alignment of the windings.
