Summary:PURPOSE:To stabilize the electric performance of a prefabricated connection part under a high electric field and under a high temperature and to enhance its thermal and mechanical characteristic by a method wherein an epoxy unit is manufactured from an epoxy resin which uses alumina as a filler. CONSTITUTION:A prefabricated connection part is constituted of an epoxy unit 10, a premolded insulator 20 and the like. The component materials are manufactured at a factory and assembled and executed at a site. An alumina- mixed resin is provided with a favorable property in terms of an electric characteristic and a thermal characteristic as compared with a silica-mixed resin. Consequently, when it is used for the epoxy unit in the prefabricated connection part aiming at a high-voltage and compact unit, its tolerance with reference to the required performance can be increased. As a result, the electric performance of the prefabricated connection part under a high electric field and under a high temperature is ensured and stabilized, and its thermal and mechanical characteristic can be enhanced.
