Heat tracing cable working principle?The most widely used electric heating cable is the self-limiting temperature heating cable. In the actual heating application, it can reach more than 80% utilization rate of the heating system. The self-limiting temperature heating cable is composed of a conductive polymer, two parallel metal wires and an insulating sheath. Its characteristic is that the conductive polymer has a very high positive temperature coefficient characteristic, and they are connected in parallel, can automatically adjust the output power with the temperature change of the heated system, automatically limit the heating temperature, and can be arbitrarily shortened or used in a certain range,What are the influencing factors of uneven heating of electric heating tape?Heating principle of electric heating cable
When the temperature becomes cold, the plastic returns to the state of micro-molecular contraction, the carbon particles are connected to form a circuit, and the heating power of the heating tape automatically rises.The self-limiting temperature heating cable has the advantages that other heating equipment does not have. The temperature controlled by it will not be too high or too low, because the temperature is automatically adjusted.
In summary, the self-limiting temperature electric heating cable has the advantages of preventing overheating, easy to use and maintain, and energy saving. It is suitable for temperature control, heat tracing, heat preservation, and heating of pipelines, equipment and containers, especially when materials are easily decomposed, deteriorated, crystallized, and frozen by condensation. It has a wide range of uses in petroleum, chemical, electric power, metallurgy, light industry, food, refrigeration, construction, gas, agricultural and sideline product production, processing and other sectors.
