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.

Abstract: A description is given of a flexible electric control cable in which one or more layers of control wires are stranded on a central element and the at least one layer of control wires is surrounded by an outer jacket, the central element (1) comprising at least one pair of wires (1a, 1b) and each wire (1a, 1b) of the pair of wires comprising a core element (10) of a tension-resistant plastic, a layer of metal wires (11) stranded on the core element (10) and a layer (12) of a compressible insulating material sheathing the stranded layer, and the wires (1a, 1b) of the pair of wires being stranded with one another with a length of lay of 20 to 40 D, where D is the diameter of the pair of wires.

Abstract: The invention describes a flexible multicore electrical cable with a central supporting member (3), several cores (1) that includes insulated fine-strand conductors and surround the supporting member (3), and a plastic sheath (5), wherein the central supporting member (3) includes a torsionally rigid steel cable (3a), which is provided with an outer layer of insulation (3b). The steel cable (3a) includes a core strand (6), a first course of several strands (7) stranded on the core strand (6), and a second course of several strands (10) stranded on the first course, wherein the direction of lay and/or the length of lay of the strands (10) of the second course is different from the direction of lay and/or the length of lay of the strands (7) of the first course.
