PSR heating cable

PSR self-regulating heating cables provide the most versatility in heat trace designs and applications. Constructed of a semi-conductive 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 temperature increases, the heater’ s resistance increases, which lowers the output wattage. Conversely, as the temperature decreases, e resistance decreases and the cable produces more heat. So thermostat is not necessary in some applications. It will never overheat or burnout even when overlapped. The cable can also be cut to any length. As the result, we get an energy efficient heating cable. With optional outer jackets, the heating cable is resistant to watery and inorganic chemicals and protect against abrasion and impact damage.
