Abstract:
1. A flexible electrical line, comprising: in a core, at least one sensor element; and leads composed of insulated electrical conductors which are surrounded by a common outer casing of insulation material, wherein the sensor element is composed of always two leads each having an insulated electrical conductor with a tension-proof central element, which are stranded together into a unit with two filler strands composed of insulating material, wherein the unit is surrounded by a banding of insulation material over which a casing is arranged, wherein, arranged in the core of the line, are arranged as electrical leads, three phase leads, which are stranded together and serve for transmitting energy with voltages above 1 kV, wherein the phase leads each have at least one inner conductive layer surrounding the conductor and an insulation above the conductor layer, wherein the conductors of the leads of the sensor element are composed of copper wires which surround the tension-proof central element in two layers with oppositely directed stranding directions, wherein the insulation of the leads of the sensor element is composed of a cross-linked elastomer material which is applied by extrusion and has a dielectricity number of at least 6.0 at room temperature, wherein the unit of leads and filler strands which are stranded together are surrounded by a coating of an electrically conducted polymer material, and wherein, the core of the line composed of phase leads and sensor element is surrounded by a common inner casing produced by extrusion, above which the outer casing is arranged.
