Abstract

PURPOSE:To improve crack resisting property by providing the interface between a winding and a ground insulator having a mechanically large stress alleviating layer. CONSTITUTION:A layer between wound conductors 1 is insulated 2, in a winding 3. A glass fiber layer 4 is formed by winding the glass fiber around the winding 3. The stress alleviating layer 5 is formed by impregnating synthetic resin in the layer 4 and cured. The ground insulator 6 is cast by a cast molding material. Even though cracks occur in the stress alleviating layer 5 due to the increase in temperature of the winding 3 during the operation, the layer 5 is not crumbled owing to the presence of the glass fiber layer 4. The stress is alleviated by the stress alleviating layer 5, and the cracks do not spread to the ground insulator 6.
