We divide electric heating cables with different heating methods into self-limiting temperature electric heating cables, series constant power electric heating cables and parallel constant power electric heating cables. All kinds of heating cables are widely used in people's production and life according to people's different needs. So what are the differences in the practical application of parallel constant power electric heating cables?
In this regard, first of all, we need to understand the composition of the parallel constant power electric heating cable, the parallel constant power electric heating cable, the resistance wire is connected in parallel, and the resistance wire is used to heat the object to heat the object, precisely because of its parallel connection. In this way, the electric heating cable is called a parallel constant power electric heating cable. Therefore, for the parallel constant power electric heating cable, it can be cut according to the heating section of the heating. Therefore, the parallel constant power electric heating cable is more convenient and simple in daily installation and use, and the daily maintenance is also more convenient.
In addition, the constant-power electric heating cable is connected in parallel, and the heating distance is longer (up to 300m) than the self-limiting temperature electric heating cable. It is more effective for storage tanks and large-diameter pipeline heating cables. In addition, the power of the parallel constant power electric heating cable is constant and the heating temperature is high, so the constant power electric heating cable can meet more heating needs, and a special temperature controller can be added to adjust the temperature of the heating cable to prevent the temperature from being too high. Influence of heat tracing medium. Compared with the self-limiting temperature electric heating cable, the constant power electric heating cable does not have too many power points, and the maintenance is convenient and simple.
Compared with the constant power electric heating cable in series, it needs to be customized and used, and the parallel constant power electric heating cable is more convenient to install and use. The heating distance is longer, so the parallel constant power electric heating cable effectively makes up for the weakness of the self-limiting temperature electric heating cable and the series constant power electric heating cable, and more effectively meets the needs of various heat tracing.
