Abstract
An apparatus for conducting alternating current through a well barrier made substantially entirely of ferromagnetic material includes at least one non-ferromagnetic electrically conductive rigid tube extending through its own separate passageway in the well barrier. A single electrical conductor carrying the alternating current, extending through the well barrier, is enclosed by each rigid tube. The electrical conductor includes insulation electrically isolating the rigid tube from the conductor.
