ABSTRACT:
A flexible heating cable and method using positive temperature coefficient conductive (PTC) polymeric material as the primary heat source with the PTC composition material being electrically and mechanically connected to substantially flat, preferably braided, electrical conductors. A covering of dielectric material preferably is used to electrically separate the cable from the environment. The cable construction improves the heat transfer from the PTC composition material to the environment, thereby increasing the power generated by the PTC composition material. Additionally, the cable construction improves the temperature distribution of the cable.
