Abstract
An electrical penetrator for subsea use has an annular cavity between the connector pin and the body of the penetrator that is filled with a dielectric oil which may act as a pressure compensator. In certain embodiments, a plurality of nested boot seals provide a watertight seal between an electrical cable and the body of the penetrator. An inner boot seal has a stepped inner diameter which engages a central, axial, connector pin and at least one wall of a cylindrical projection or an annular recess formed in the external face of the penetrator body. An outer boot seal has a stepped inner diameter which provides a watertight seal to an attached electrical cable, the connector pin and an outer segment of the inner boot seal.
