Self-regulating heating cable series
Product Detail

GW high temperature series

Product Description
Self-regulating heat tracing cable is widely used in in pipelines, storage tanks and civil pipelines of petroleum, chemical engineering, steel, power and other industrial enterprises for heat tracing, thermal insulation, anticoagulation and antifreezing. The cable is suitable for common area, the dangerous area and the corrosive area.
Features of heating cable:
●Heating cable corresponding to heat tracing system has a feature of automatically adjustment of the output power, Therefore, it will not be burned for self-heating, and able to make heat compensation according to the actual needs, so it is the energy-saving and intelligent electric heater with only strip thermostat.
●Low-temperature start quickly, uniform temperature, high-temperature limit temperature automatically, whole or in part can be adjusted automatically with the temperature change of heat tracing, without additional temperature control device.
●Easy to install and simple to maintain, AC and DC, with wide operating voltage and adaptation, high level of automation, low operating and maintenance costs.
● can be cut at any length and lengthening use within a certain range, allows multiple overlapping but no high temperature hot point or burning. The application of far-infrared radiation technology for transforming has no damage to human body.
