Abstract
A skin effect heating cable used to form a heat tracing circuit for heating a production pipe carrying process media. The skin effect heating cable includes a heating tube which includes a conductor, an insulating layer wrapped around the conductor and a dielectric fluid disposed between the insulating layer and the inner wall of the heating tube. The dielectric fluid increases the heat transfer characteristic from the conductor to the heating tube while providing mechanical load relief to the cable.
