At each scanning process four measuring values are provided, giving a very precise measurement. An important development is the integration of ceramic windows (patent pending), which separates the scanners from the pressure of the CV-line. This replaces the previously used beryllium windows and prevents contamination in the measuring plane. The surface of the ceramic windows does not react with any by-products and always remains clean without rinsing and mechanical protections. The product planning of the X-Ray 8000 NXT was specifically adapted to the demands of the modern high-voltage cable production. Today, 500 kV-cables and higher are produced, with greater wall thicknesses and a specific measuring plane. Additionally, the expansion of the hot material results in a bigger hot diameter. For the measurement of EPR-cables with extremely large diameters Sikora offers a 70-kV-scanner-model, to ensure highest quality at the production. In practice the X-Ray 8000 NXT offers high efficiency. With regard to eccentricity, the wall thickness is measured and controlled, for highest quality and productivity. Material consumption is reduced, resulting in cost reduction. Sikora International Corp – USA Email : sales@sikora-usa.com Website : www.sikora.net

Sikora’s X-Ray 8000 for the measurement of wall thickness, eccentricity as well as the diameter and ovality of high-voltage cables has been improved regarding design and technology. The focus of the further development was on profitability and technological progress. The optimised technology was sum- marised under the name X-Ray 8000 NXT (NeXT generation) for an optimum quality control at the production of MV-, HV- and EHV-cables in CCV-, VCV- and MDCV-lines. With the new X-Ray 8000 NXT for XL diameters, Sikora is now presenting a new model of this series, which combines the technological advantages of the X-Ray 8000 NXT with regard to the practical application in the field of EHV-cable (Extra High Voltage cable) production. The “measuring giant” is perfectly suitable for extremely big cable diameters of up to 180mm for CCV-lines and 220mm for VCV-lines. It provides highest measuring accuracy and repeatability while demonstrating the flexibility and safety of an X-Ray 8000 NXT. As with the X-Ray 8000 NXT, the XL-system requires only one scan to calculate all measuring values. Hence, all requirements for rapid centring of the extrusion tools as well as optimum control of the production line. Multi-sensor semi- conductor detectors are incorporated into the high-end variant of the X-Ray 8000 NXT. The multi-sensor- technology assures reliable readings and ensures reliable measuring values – even when the cable is vibrating.
