  • Patent number: 5976449
    Abstract: A method and an apparatus for measuring an electric insulated conductor, in particular a medium-voltage and/or high-voltage insulated conductor, are proposed. Seen in profile cross-section, the insulated conductor (50) includes a copper conductor, an inner semiconductor, an insulation and an outer semiconductor and is produced in an extrusion device (90) having an appropriately assigned crosslinking section (40). To achieve an even distribution of the two semiconductor layers and of the insulation layer, the insulated conductor (50) is radiated through immediately at the outlet from the crosslinking section (40) and a correction of the die setting in the extrusion device is carried out by means of values thus determined.

  • Patent number: 5795531
    Abstract: A method and an apparatus for an exact measurement of the thickness of a plurality of individual semi-conductor and insulation layers and the determination of the centricity/eccentricity of a medium-voltage and/or high-voltage insulated conductor. The individual semi-conductor and insulation layers of the insulated conductor emerging from an extrusion device are penetrated with X-rays in at least two directions laying within a plane orthogonal to the axis of the insulated conductor. On carrying out a line-scan intensity detection of the X-rays having penetrated the insulated conductor, the thickness of the individual layers as well as the position of the conductor is computed. These values are compared with target ones, and, if necessary, the position of the extruder heads can be corrected accordingly.
