With the innovative measuring system X-RAY 8000 NXT Sikora provides the
tool for an efficient concept in quality control, production optimisation and
reduced material consumption in power cable production.
X-RAY 8000 NXT is suitable for permanent quality control at the production
of MV-, HV- and EHV-cables in CCV-, VCV- and MDCV-lines. Sikora holds an
outstanding precursor position in the field of EHV-cable production.
Specifically developed for this application area the X-RAY 8000 NXT is ideal
for extremely big cable diameters up to 180mm for CCV-lines and 220mm for
VCV-lines.
The X-RAY 8000 NXT measures the
wall thickness, eccentricity as well
as the diameter and ovality with an
incomparable measuring accuracy and
repeatability. Only one scan is necessary
to calculate all measuring values.
X-RAY 8000 NXT allows the operator a fast
centring of the extrusion tools as well as
optimum control of the production line in
automatic mode.
Multi-sensor semi-conductor detectors
are incorporated into the high-end
variant of the X-RAY 8000 NXT.
This multi-sensor technology assures
reliable readings in case the cable may
vibrate and provides four measuring
values at each scanning process for a
precise measurement.
A masterpiece of engineering is the
integration of ceramic windows* and
NTX windows (Non Toxic X-Ray), which
separate the scanners from the pressure
of the CV-line.
The surface of the windows does not
react with any by-products resulting
from the cross linking process and always
remains clean. *Patent pending
