Abstract:
An electric apparatus, comprising:an iron core; low and high voltage windings concentrically arranged on an outer periphery of said iron core; insulating cylinders concentrically arranged between said iron core and said low voltage winding, between said low voltage winding and said high voltage winding and at a periphery of said high voltage winding; an insulating medium filled internally within said insulating cylinders; spacers separately arranged between ones of said insulating cylinders to form a plurality of insulating medium paths; and a flow stopping member for stopping the flow of said insulating medium in said insulating medium paths, said flow stopping member being made of an insulating material with a low density interposed between adjacent spacers at least one of the upper and lower ends of each of said insulating medium paths to close the insulating medium paths.
