Abstract
A parallel, zoned heating cable wherein parallel electrical conductors are spaced outwardly from a central heating element preferably formed of a fibrous material containing carbon or graphite or coated with a conductive polymer. Heat conducting dielectric members are preferably located between the heating element and the electrical conductors for improved thermal distribution of the cable. The conductors are alternately connected by splices to the electrical conductors to produce heat of a constant wattage.
