Self regulating heating cable provide the most versatility in heat trace design and applications. Constructed of a Semiconductive heater matrix extruded between parallet buswires, a self regulating cable adjusts its output to independently respond to ambient temperatures all along its length. As temperatures increase,the heater's resisteance increase which lower the output wattage. Conversely, as the temperature decrease, the resistance decreases and the cable produces more heat. So it is no need thermostat in some applications. It will never overheat or burnout even when wrapped by itself(overlapped). Also can be cut to any length. It is an convenient maintenance,easy use and energy efficient heating cable.
