Abstract
An electrical insulator apparatus and method of manufacturing an electrical insulator apparatus includes a core strength member which is positioned at least partially within at least one end-fitting. A thermoplastic exterior body having a plurality of spaced fins is injection-molded over the core strength member and at least partially over the at least one end-fitting. The core strength member is attached to the at least one end-fitting without a mechanical compression to the at least one end-fitting and without an adhesive between the core strength member and the at least one end-fitting. One or more mechanical upset structures formed on the at least one end-fitting prevent movements of the injection molded thermoplastic exterior body relative to the at least one end-fitting.
