Patent Number: 6,529,108

Title: Electric appliance

Abstract: In an electric apparatus, insulating cylinders having different diameters are arranged in a shape of multiple cylinders between the iron core and the low voltage winding, between the low voltage winding and the high voltage winding and on the periphery of the high voltage winding. Spacers are separately arranged between layers of the plurality of insulating cylinders to form a plurality of insulating medium paths. A flow stopping member for stopping the flow of the insulating medium in the insulating medium paths which is made of an insulating material with a low density is arranged at at least one of the upper and lower ends of each of the insulating medium paths.
