Abstract

The present disclosure relates to a bushing and a manufacturing method therefor. The bushing includes a conductive tube and a central tube. The conductive tube is fixedly connected to a bottom connecting assembly and a top connecting assembly. The central tube is fixedly connected to the bottom connecting assembly and the top connecting assembly. The central tube is subjected to a compressive force in an extending direction of the central tube, such that the conductive tube is subjected to a tensile force in an extending direction of the conductive tube. The embodiments of the present disclosure can eliminate or reduce creep or stress relaxation of composites to ensure mechanical properties and sealing performance in a life cycle of the bushing.
