Abstract
A heater cable produces a substantially level voltage across its cross-section, providing a uniform and controllable thermal output along its length. The heater cable includes at least one center bus wire extending axially along a central axis of the heater cable, and at least one radial bus wire extending axially through the heating cable and positioned adjacent to the center bus wire. The heater cable further includes a thermally and electrically conductive interstitial material disposed around the at least one center bus wire and the at least one radial bus wire, and a jacket disposed about the interstitial material, the at least one center bus wire, and the at least one radial bus wire.
