X-RAY 8000 NXT

X-ray technology for
CCV, VCV, MDCV lines

With the new innovative measuring system X-RAY 8000 NXT SIKORA provides the tools for a efficient concept in quality control, production optimization and reduced material consumption in power cable production. X-RAY 8000 NXT presents itself as the evolutionary successor of the X-RAY 8000, the industrial standard device for a reliable measurement at CV-lines. X-RAY 8000 NXT is suitable for the production of MV-, HV- and EHV-cables in CCV-, VCV- and MDCV-lines and guarantees a permanent online quality control.

It measures wall thickness, eccentricity as well as the diameter and ovality with an incomparable high measuring accuracy and repeatability. Only one scan is necessary to calculate all measuring values. X-RAY 8000 NXT allows the operator a fast centering of the extrusion tools as well as optimum control of the production line in automatic mode.

The design of X-RAY 8000 NXT incorporates multi-sensor semiconductor detectors. This multi-sensor technology assures reliable readings in case the cable may vibrate in the CV-tube and provides 4 measuring values at each scanning process and rapidly contributes to increased production efficiency. A masterpiece of engineering is the integration of ceramic windows*, which separate the scanners from the pressure of the CV-line. The surface of the ceramic windows* does not react with any by-products resulting from the cross linking process and remain clean without rinsing or mechanical protection.
