Abstract: A flexible electrical line has at least one sensor element with two leads in a core, the leads made from insulated electrical conductors which are surrounded by a common outer casing of insulation material. The core is three phase leads of a conductor and insulation which are stranded together for energy transmission. The conductors of the leads are copper wires which surround a tension-proof central element in two layers with oppositely directed threading direction. The insulation of the leads is a cross-linked elastomer material applied by extrusion with a dielectricity number of at least 6.0 at room temperature. The unit, composed of leads and filler strands of the sensor element, is surrounded by a casing of an electrically conductive polymer material, and the core of the line is surrounded by a common inner casing produced by extrusion over which is arranged the outer casing.
