System for continuous electrical well cable feed-through for a wellhead and method of installation

A sub-system for a continuous electrical well cable feed-through for a wellhead comprising:

• a non-ferromagnetic transition seal body seated on an interior shoulder of a protective mandrel and sealed on an interior surface of said protective mandrel by a plurality of O-rings and a covering of epoxy extending from the well cable to the transition seal body;
• and providing three foramen for the continuous passage of electrical conductors and having an interior shoulder in each of the three foramen;
• and,
• at least three non-ferromagnetic tubes supporting the three non-terminated electrical conductors inserted into the non-ferromagnetic transition body seated on the interior shoulder in said transition seal body.

A method for installation of a continuous electrical three-phase cable through a wellhead comprising:

• stripping the protective outer sheath down to the insulation on each non-terminated electrical conductor of a down-hole three-phase electrical cable;
• inserting each of the insulated non-terminated electrical conductors into a non-ferromagnetic tubing;
• inserting each non-ferromagnetic tubing into a non-ferromagnetic transition body seating the end of each non-ferromagnetic tubing against an interior shoulder in said transition body;
• distributing epoxy around the insulated non-terminated electrical conductors covering the exposed end of the protective outer sheath of the electrical three-phase cable and covering each of the tubes extending from the non-ferromagnetic transition body;
• enclosing the non-ferromagnetic transition body, seal and epoxy covered non-terminated electrical conductors within a protective mandrel;
• and,
• inserting the mandrel into the wellhead hanger.
