Next generation X-Ray 8000 NXT

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.

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 centering 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. At each scanning process four measuring values are provided for a remarkably precise measurement. is the integration of ceramic windows (patent pending), which separates the scanners from the pressure of the CV-line. This replaces the previously An important development

The successful X-Ray 8000 for the measurement of wall thickness, eccen- tricity 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 summarised 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. X-Ray 8000 NXT is perfectly suitable for extremely big cable diameters of up to 180mm for CCV-lines and 220mm for VCV-lines. It provides highest
