Principle of heat tracing cable: After connecting the electric heating belt to the power supply (noteTail end wire coreDo not connect), the current passes through a conductive wire corePTC materialForm a circuit by connecting to another wire core.electric energymakeconductive materialWhen the temperature rises, its resistance immediately increasesCore stripAfter the temperature rises to a certain value, the resistanceBig toAlmost to the extent of blocking the current, its temperature no longer rises, and at the same time, the electric heating belt transfers heat to the heated system with lower temperature. The power of the electric heating belt is mainlyControlled byThe heat transfer process automatically adjusts the output power according to the temperature of the heated system, while traditional constant power heaters do not have this function.
