Tough construction
Our self-regulating heating cables consist of two parallel tin-plated copper conductors, embedded in a semiconductive heating core, and electrically insulated by a polymeric jacket. Some types are additionally jacketed with a tin-plated copper braid which may serve as earthing, as personal protection according to VDE 0100, and as further mechanical protection.

How it works
The self-regulating heating cable automatically adjusts to the ambient temperature conditions. Low ambient temperatures call for high heat output, higher temperatures call for less or no heat output. The principle is rather simple: Between two copper conductors, electric current passes through a radiation-crosslinked polymer heating core. The carbon particles embedded in this core create electrical paths between the conductors. As the temperature rises, the core expands microscopically, so that the distance between the carbon particles increases. The number of electrical paths is thus reduced, so that the heat output decreases. The procedure is reversed when the ambient temperatures are low: The distance between the carbon particles decreases, and the rising number of electrical paths increases heat output. The heating core is radiation-crosslinked in order to achieve duroplastic properties which make thermo-plastic expansion exactly reproducible, even in strongly deviating ambient temperatures. The self-regulating features are thus fixed within the material.
Cost-effective and secure application
As heat output is adjusted to the respective ambient temperature conditions, energy consumption is reduced to the amount required. Therefore our self-regulatig heating cables save energy and costs automatically. Moreover, the self-regulating features of the heating cables prevent the risk of overheating or burn-out. They can be applied safely even in plastic pipes or plastic gutters.
Economical planning and installation
The heating cable can be cut to lengths on the site. Branches and joints are easy to make thanks to parallel connection and the RayClic connection system. Whatever the total length of the heating cable may be, it is always connected to a 230 V power supply. Our heating cables are the ideal solution both when directly integrated in new-built structures, or retrofitted in existing sites and buildings. They are durable for a period of more than 40 years.
