Product Name: HWSR



HWSR Self Regulating Heating Cables is highly efficient both to protect freezing and to maintain temperature for hot water supply pipes. 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. It will never overheat or burnout even when wrapped by itself (overlapped). And it can be cut to any length. The result an energy efficient heating cable. 

Especially, the self-regulating conductive core and insulation jacket of HWSR are treated with irradiation cross-linking reaction, yielding excellent heat resistance and cable stability in long term operation.

1.Long life time:PTC semi-conductive matrix with high quality and excellent technology.

2.Low energy consumption:Due to unique PTC property, the cable adjust the output power respond to ambient temperature.

3.Excellent heat resistance:PTC semi-conductive matrix is treated by irradiation crosslinking reaction. High insulation resistance

4.Cut to length:PTC semi-conductive matrix is composed of the infinite parallel connection of carbon particles, allowing it to be cut to the exact length required.

5.Easy for installation : Linear cable, complex installation available, never overheat when overlapped.

6.Low starting current : PTC 3 layer co-extruded technology, low starting current and low Attenuation rate.

7.Cable durable : UV protection, high and low temperature resistant, weather resistant.



HWSR is very effective to protect hot water supply pipes from freezing with low energy consumption.
