FSR Series
FSR Self Regulating Heating Cables provide the most versatility in heat trace designs and applications. Constructed of a semiconductor 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. The result —an energy efficient heating cable. with optional outer jackets, the heating cable is resistant to watery and inorganic chemicals and protect against abrasion and impacted damage.

Our Advance:
Three layer co extrusion technology
1)Principle
Three layer co extrusion technology of self regulating heating cables, which is characterized in that: two metal wire coated with a low resistance layer, a conductive layer, insulating layer and the insulating layer, a metal shielding net. Among them low resistance layer, conductive layer and the insulating layer of the three layer of a extrusion. 
2)Advantages
The two metal wire coated with new low resistance layer, the insulation layer of the conductive layer, forming a three layer with the extrusion production process, the conductive layer and the insulating layer structure closely No gap, no air, no impurities, reducing self heating single fault rate and decay rate, convenient and safe, long service life.
Due to low resistance between the transition layer and the PTC contact closely, effectively reduce the starting current, the current impact to the material of PTC, prolong service life, reduce the 3)starting current.
The inner insulation layer using the self-made insulation, due to the special nature of PTC material, the market most of the insulation of PTC will be more or less damage, and we use a unique formula of self insulation, insulation itself does not have any damage to the PTC, Between the insulation and PTC is compact in structure, can effectively waterproof. In addition to our self insulation and good weather resistance, low temperature resistance, high temperature, anti ultraviolet radiation.
4)Safety
The traditional production process of self regulating heating cables between the combination does not close, the air and impurities are not fully discharged, electric heating at high temperature for a period of time it caused by the metal electrode and the PTC heating element
The contact surface of the separation failure, resistance caused by fire, with three layers of extrusion technology development and application, effectively put an end to these potential risks, to avoid the fire, security.
5)Process

The three layer with double insulation extrusion technology (the world's first) with the tropics, forming a two insulating layer of the production process in the three layer of the application with the extrusion technology, three layer with double insulation extrusion technology to improve the insulation performance with the tropics, increased mechanical strengthen extend the service life.
