Automatic temperature control electric heating flat ribbon cable tropical by two parallel metal wire and the insulating sheath. Its characteristic is that the conductive polymer composite has the positive temperature coefficient "PTC" characteristic, and is connected with each other in parallel. It can automatically adjust the output power with the temperature change of the heating system, and automatically limit the heating temperature. The characteristics of "PTC", that is, the positive temperature coefficient effect, refers to the increase of resistivity of materials with the increase of temperature and the sharp increase of resistivity at a certain temperature range. Self controlled warm band can be arbitrarily cut or used in a certain range of internal length, and allows repeated overlap, without high temperature, hot spots and burnout. The temperature control heating cable has the advantages that the temperature control cable cable corresponding heating system has automatic adjustment of output power, therefore not due to their own heat and burned, but due to the actual needs of the heat compensation, so as a new generation of energy-saving type constant temperature heater. The low temperature condition starts quickly and the temperature is uniform. Each part can be automatically adjusted because of the change of temperature at the heat tracing zone. Simple installation, simple maintenance, high automation, low operation and maintenance cost. The utility model has the advantages of safety, wide use, no environmental pollution and long service life.
1. with the heat pipe temperature is uniform, not overheating, safe and reliable.
2. save energy, low operating costs.
3. intermittent operation, heating start fast.
4. installation and maintenance is simple and convenient for automatic management.
5. environmental protection, no environmental pollution.
Widely used in fire, oil, chemical, steel, power and other industrial enterprises, pipelines, storage tanks with heat preservation, anti coagulation, antifreeze. The highest dielectric constant temperature of 0-130 degrees, the cable is suitable for general areas, dangerous areas, corrosion areas and other places to use.
