The carbon particles gradually separate, causing the circuit termination, the resistance rises, and the heating cable will automatically reduce the power output. When the temperature becomes cold, the plastic returns to the shrinking state of the micromolecules, and the carbon particles are connected accordingly to form a circuit, and the heating power of the heating cable automatically increases. The self-limiting temperature electric heating cable keeps the temperature of the door frame within a certain range, preventing the door frame from being unable to open due to freezing due to low temperature.
