How the Self-regulating Electric Heating Cables Work?

Self Regulating Heating Cables provide the most versatility in heat trace designs and applications. Constructed of a semiconductive heater matrix extruded between parallel bus wires, a self- regulating cable adjusts its output to independently respond to ambient temperatures all along its length.  As temperatures increase, the heater’s resistance increases which lower the output wattage. Conversely, as the temperature decreases, 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.
