Abstract
A process of manufacturing an insulator having a central core and an insulating body fitted tightly around the central core includes interposing a flexible coating layer between a part of the central core and the insulating body. The flexible coating layer fills in shrinkage cavities and compensates for a retraction effect caused by injected material used in forming the insulating body. The insulating body is achieved by overmolding the central core previously coated with the flexible coating layer with an injected insulating resin such as a thermoplastic or thermosetting resin. The insulator could be used as a capacitive divider or bushing insulator.
