Subsea electrical penetrator

Subsea electrical penetrator

An electrical penetrator (100,200,300) for subsea use has an annular cavity (170,270,370) between the connector pin (116,216,316) and the body (114,214,314) of the penetrator (100,200,300) that is filled with a dielectric oil which may act as a pressure compensator. In certain embodiments, a plurali...

Zusammenfassung:An electrical penetrator (100,200,300) for subsea use has an annular cavity (170,270,370) between the connector pin (116,216,316) and the body (114,214,314) of the penetrator (100,200,300) 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 (118,218,318) and the body (114,214,314) of the penetrator (100,200,300). An inner boot seal (138,238) has a stepped inner diameter which engages a central, axial, connector pin (116,216,316) and at least one wall of a cylindrical projection (115,315) or an annular recess (280) formed in the external face (128,228,328) of the penetrator body (114,214,314). An outer boot seal (150,250) has a stepped inner diameter which provides a watertight seal to an attached electrical cable (118,218,318), the connector pin (116,216,316) and an outer segment of the inner boot seal (138,238).
