A method of manufacturing an electrical penetrator assembly () comprising a penetrator housing () having a through-bore and an internal support surface; a ceramic sleeve assembly () sealingly providing a feed-through for an electrical conductor (), which sleeve assembly comprises first and second outer support surfaces; and a compression member () comprising a compression surface; said method comprising the steps of sealingly attaching at least one metal, annular sealing member () to a section of the sleeve assembly; positioning the sleeve assembly in the through-bore of the penetrator housing such that the first, outer support surface is brought into contact with the internal support surface; attaching the compression member to the penetrator housing such that the compression surface is brought into contact with the second, outer support surface; by means of the compression member, directly or indirectly preloading the sleeve assembly by applying a force onto the sleeve assembly such that a predetermined contact pressure is obtained between the first, outer support surface and the internal support surface; and directly or indirectly, sealingly connecting the at least one sealing member to the penetrator housing. The invention also relates to an electrical penetrator assembly manufactured according to the method.
