High pressure electrical cable packoff and method of making
This patent describes a method of making a high pressure electrical cable packoff for an oilwell wellhead in a casing and surrounding a production tubing in which the cable includes at least one electrical conductor, an insulator around each conductor, a jacket around the insulators, and a protective metal exterior. It comprises: at a longitudinal section of the cable removing the metal exterior and removing the jacket, bonding a resin block to the insulation where the metal exterior and jacket were removed and extending the block outwardly beyond the outside of the cable, and molding a resilient sealing ring around and enclosing the block and the longitudinal section of the cable where the metal exterior and jacket have been removed.
