Electrical feedthrough

摘要

An electrical power feedthrough connection for supporting and sealing a well electrical cable. A sealing insulator which is longitudinally split includes one or more cavities. An elongated connector is positioned in each cavity connecting the ends of two lines of the electrical cable with potting compound positioned in the cavity for sealing about the connector. A sealing grommet at each end of the insulator aligns the lines of the electrical cable with the cavities of the insulator. A cable gripping retainer is positioned adjacent each grommet remote from the insulator. A housing surrounds the insulator, grommet and retainers and includes first and second telescoping parts with threaded means for telescoping the first and second parts together. Coacting wedges are positioned between each of the housing parts and one of the retainers for causing the retainers to move inwardly and grip the cable when the first and second housing parts are telescoped together and coacting shoulders are provided between each of the housing parts and opposite ends of the insulator for compressing the insulator and sealing it about the connectors.
