PURPOSE:To provide a method of inter-layer insulation in coil layers providing good insulation and work efficiency and being economical, by insulating between a plurality of layers of coil using an insulating cylinder formed by an elastic nonconducting material. CONSTITUTION:On a primary coil wound around a winding frame 3, an elastic insulating cylinder 5 such as rubber is mounted so as to cover the primary coil, and a secondary coil 2 is wound around it. Since the insulating cylinder 5 is elastic, some change is allowed in size of the diameter of the coil to be wound around it. In addition, the insulating cylinder 5 is also fully closely contacted with the coil to be covered, it is superior in working efficiency and economy as well as in insulation. |
