Abstract
Embodiments of the invention provide a self-regulating heating cable. The cable includes a primary jacket including a first low-smoke, zero halogen material. The cable also includes a braid surrounding the primary jacket. The cable also includes a final jacket surrounding the braid and comprising a second low-smoke, zero halogen material. The final jacket is formed to the braid during an extrusion process in order to create a mated connection between the final jacket and the braid.

A self-regulating heating cable comprising:
- a semi-conductive heating core;
- two conductive wires embedded within and separated by the semi-conductive heating core;
- a primary jacket surrounding the semi-conductive core and comprising a first low-smoke, zero halogen material;
- a braid surrounding the primary jacket;
- and
- a final jacket surrounding the braid and including a second low-smoke, zero halogen material, the final jacket formed to the braid during an extrusion process in order to create a mated connection between the final jacket and the braid.
A self-regulating heating cable comprising:
- a primary jacket comprising a first low-smoke, zero halogen material;
- a braid surrounding the primary jacket;
- and
- a final jacket surrounding the braid and comprising a second low-smoke, zero halogen material, the final jacket formed to the braid during an extrusion process in order to create a mated connection between the final jacket and the braid.
A manufacturing process for producing a heating cable, the manufacturing process comprising:
- receiving a partially finished heating cable comprising parallel conductor wires, a core, a primary jacket, and a braid;
- forming a final jacket to the braid to create a mated connection between the final jacket and the braid;
- and
- outputting a finished heating cable including the parallel conductor wires, the core, the primary jacket, the braid, and the final jacket.
