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.
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.
