Description

Via two tin-coated stranded copper wires with a cross-section of 1 mm? each which are positioned in parallel, an irradiated electrically conducting plastic is extruded.

This electrically conducting plastic matrix responds to changes of the ambient temperature with a respective increase or decrease of the heating output.

Electrical strength as well as protection against humidity and mechanical stress is ensured by two surrounding insulation jackets, whereas the first jacket is permanently bonded to the heating matrix (bonded jacket).

Additional electrical and mechanical protection is achieved by means of the following copper braiding.

A flame-retardant, UV-resistive plastic jacket protects the braiding against humidity and offers further protection against major mechanical stress.
