Electric tracing cables can be divided into self-limiting temperature series, constant power series and MI armored heating cables, among which the self-limiting temperature series is a common model in electric heating products, which is composed of conductive polymer and two parallel metal wires It is composed of an insulating protective layer, which is characterized by the conductive polymer having a high positive temperature coefficient characteristic, and they are connected in parallel, which can automatically adjust the output power according to the temperature change of the heated system, and automatically limit the heating temperature.
The self-limiting electric heating cable has uniform temperature, no overheating, quick heating start, energy saving, easy installation and maintenance, and has been widely used in antifreeze, heat tracing, heat preservation, viscosity reduction, etc. of pipelines, equipment and containers in various industries.
