PURPOSE:To enable tap windings to be insulated corresponded to the allotment of voltage between the tap windings by a method wherein insulated two single conductors are arranged in parallel and the tap windings are formed by using two conductor insulated wires of the two single conductors applied with common insulation. CONSTITUTION:There are the four tap windings a, b, c, d, six poles of tap terminals and five voltage conversions. In this case, the tap windings can be made a construction having a rational insulation corresponded to a voltage applied between the tap windings by in parallel arranging the two single conductors and by constructing the tap windings using the two conductor insulated wires of the two single conductors further applied with the common insulation. That is, since the tap windings therebetween applied the voltage as much as 1 tap-step are insulated by the insulation of the only single conductor insulated wire and the tap windings therebetween applied with the voltages as much as 2 taps are insulated by the insulation of the single conductor insulated wire and the common insulation, the insulation propertionate to the voltage can be applied by making the both insulation thicknesses same and an operation efficiency can be improved. |
