Self stabilizing heating cables

cpsshlibpgeflechtniedrigSelf stabilizing heating cables are defined - as the name already indicates - as heating cables which stabilize at a certain maximum temperature, being typical for heating cables. This process is realised with a resistor material in the heating core that is changing according to the ambient temperature. The core or the self stabilizing heating cable, called matrix, consists of a mixture of graphite particles and polymer. The graphite particles form innumerable parallel connections between two parallel copper supply cables, which are embedded into the matrix. If the heating tapes cool down, the graphite particles in the matrix approach towards each other and increase the parallel connections between the copper supply cables. In consequence, the ohmic resistance decreases and the power of the heating cable rises. If the heating cable warms up, the graphite particles diverge apart from each other and decrease the amount of parallel connections between the copper supply cables. In consequence, the ohmic resistance increases and the lower flow causes the heating cable to cool down.
The process repeats itself until a thermal balance between thermal losses and heat output of the heating cable is reached. This point lies below the maximum operating temperature of the material of the heating cable. In this way, overheating is not possible. Due to its flat oval cross section, the flexible heating cable covers a very large part of the surface to be heated and can thus release the thermal energy very efficiently.
However, due to its design, the heating cable can be installed in meandering shape (loop-shaped) only to a limited extent.
Therefore, primarily pipelines and cylindrical objects can be coated with this heating cable. According to the temperature and application, a special heating cable is created for you.

In the following you can find a variety of characteristic heating cables of different temperatures:
