Constant Wattage Parallel Heat Trace Cable (CWPHT)

Self regulating heating cable provide the most versatility in heat trace design and applications. Constructed of a Semi-conductive heater matrix extruded between parallel buswires, a self regulating cable adjusts its output to independently respond to ambient temperatures all along its length. As temperatures increase,the heater’s resistance 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). It can be cut to any length. So it is a convenient ,easy use and energy saving product.
