Abstract: A three-conductor cable (10) including three stranded electric cables (1), each having a core that has a current conductor (2) and a neutral and/or return conductor. Each individual cable (1) is essentially characterized in that the neutral and/or return conductor is configured from a number of individual conductors (4), distributed concentrically around the current conductor (2), that an insulating sheath (3) is provided between the current conductor (2) an the distributed individual conductors (4) of the neutral and/or return conductor and that a protective jacket covers the neutral and/or return conductor.

Abstract: An electric cable is configured as a sensor cable, wherein the lead insulation of the cable has a polymer layer. The sensor cable can be produced by, after extruding the raw cable, cutting the cable into individual cable sections in a non-crosslinked state. The sections are then connected to a sensor in an electrically conductive manner. The housing of the sensor consists of a plastic material that is compatible with the lead insulation and that is radiation crosslinkable. The polymers of the lead insulation and the polymers of the sensor housing are crosslinkable with themselves and with one another. A compatibilizer or a reactive terpolymer enabling connection of functional groups between the layers can also be added to the lead insulation and/or the plastic housing. The plastic materials of the lead insulation and the sensor housing are crosslinked in a separate crosslinking process under the effect of high-energy electron radiation.
