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.
