Abstract
A flexible heating cable using positive temperature coefficient thermistors as a primary heat source with the thermistors being electrically and mechanically connected to substantially flat, preferably braided, electrical conductors with dielectric material preferably separating the 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 thermistors to the environment and improves the temperature distribution of the cable.
