CE,EAC,IEx e IIC T6 Gb X,Ex tb IIIC T85°C Db XConstructed 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 overlapped. And it can be cut to any length. As the result, we got an energy efficient heating cable.
Especially, the self-regulating conductive core and insulation jacket of HWSR are treated with irradiation cross-linking reaction, in order to attain excellent heat resistance and cable stability in long term operation.
The unique advantages of Huanrui self-regulating heating cable:
1. Improve the temperature resistance level: The temperature resistance level of the PTC semiconductor irradiation heating matrix can reach 100-110°C as needed to improve operational safety.
2. Reduce the starting current: Huanrui adopts double-layer co-extrusion technology, the starting current in the normal power range reaches <0.3A/M, and the ratio of starting current to steady-state current is less than 3 times.
3. Advanced insulation material: The insulation material is 100% matched with the PTC semiconductor irradiation heating matrix. In addition, it has excellent weather resistance, high temperature resistance, and insulation resistance of >2000MΩ, making it safer and more reliable.
4. New process: Huanrui adopts multi-layer co-extrusion technology. The insulation layer and PTC semiconductor irradiation heating matrix are extruded at the same time and completed in one go. The heating matrix and insulation are seamlessly integrated and cannot be peeled off, completely eliminating moisture and water when immersed, impurities cannot harm the core tape. Improve product service life.
Never overheat or burnout when overlapped. Cut to any length. Easy to install.
HWSR-P: Tinned copper braid provides additional mechanical and ground protection.
HWSR-PB: Flame retardant thermoplastic outer jacket protects against certain inorganic chemical solutions, it also protects against abrasion and impact damage.
HWSR is very effective to protect hot water supply pipes from freezing with low energy consumption.
