Abstract

PURPOSE: To improve partial discharge characteristics by providing a shield ring, which has a radius of a curvature larger than thickness of an attaching plate which is to become grounding side, on an attaching end section of a bushing formed by filling an insulation layer on surroundings of a conductor.
CONSTITUTION: An insulation material such as epoxy resin, etc. is vacuum-formed in a conductor 11, a resin bushing main is composed by forming an insulation layer 12 on surroundings of the conductor 11 and an attaching plate 13, which was punched out from a steel blank into a circular shape, is attached onto a flange- attaching end section 12a located in a center section of outer circumferential surface of the insulation layer 12. And a metallic shield ring 14, which has a radius of a curveture larger than thicknes of the attaching plate 13, is attached onto the attaching end section 12a along the attaching plate 13 by welding, etc. By doing so, partial discharge characteristics can be improved by alleviating electric field on grounding side with an outside shield ring without burying the shield ring in the inside of the insulation layer, and at the same time, quality can also be stabilized.
