Electric Heat Tracing Cable Overview
After power is turned on (note: the end core wires must not be connected), current flows from one core wire through the conductive PTC material to the other core wire, forming a circuit. The electrical energy heats the conductive material, causing its resistance to increase. When the core temperature reaches a certain value, the resistance becomes so high that it almost blocks the current, and the temperature no longer rises. At the same time, the electric heat tracing cable transfers heat to the lower-temperature heated system. The power of the electric heat tracing cable is mainly controlled by the heat transfer process, automatically adjusting the output power according to the temperature of the heated system, while traditional constant power heaters do not have this function.
