Abstract

PURPOSE: To prevent a moisture absorption of a winding in assembling or disassembling the winding by attaching a film which is not permeable to moisture nor absorbing the same on the outer surface of an external insulated cylinder, providing an air-tight sealing for the cylinder and plate and forming the insulator not permeabl to moisture so that the cylinder is provided to surround the immediate portion between the inside insulation cylinder of the winding and core leg and the winding supporting insulator is opposed to a winding support fittings.
CONSTITUTION: A cylinder made of hexafluoro resin is provided between an inner insulated cylinder 3 and core leg 1, and an insulation plate 8 having the same material as the cylinder is disposed between a support fittings 5 and the outer surface of a support insulator 6 for a winding 2 and the jointed portion between a cylinder 7 and it is air-tight sealed. A polyethylene film 9 is wrapped around the outside of an outer insulated cylinder 4, an adhesive tape is sticked to a sealed portion to bond the upper and lower ends of the film 9 by a string 10 to the jointed portion of the insulated plate 8 thereby preventing entering of the air. The film 9 is mounted before a disassembling work and removed after the assembling. According to such a method, the moisture absorption by the winding is effectively avoided.
