technology news
Nexans has completed a contract worth approximately
€1,000,000 to supply low-voltage power cables for the
BioWanze project – a new plant producing bioethanol from
wheat and sugar beet. The plant, located in Wanze near
Huy sur Meuse (Belgium), will produce half of the annual
bioethanol volume for the Belgian market, or 125,000m3 per
annum during the next six years.
Nexans entered a frame agreement with Siemens NV/SA, the
contractor in charge of project engineering and management,
for the supply of approximately 350km of low-voltage (LV)
power cables in only five months, with over one hundred
different product references. The cables were manufactured
by Nexans production facilities in Belgium, located in Dour
and Buizigen.

Biofuelled contract
Operators of multi-purpose lines can make use of a sector gauge
head with integrated 3-axis diameter measurement function for
measuring ranges of up to 100mm. With this technology Sikora
reacts to customer demands for multi-function measurement
systems for different product applications in one production
line. The “two in one” gauge head is based on a newly
developed sandwich principle. For this application the Laser
2100 S/R is combined with the Laser 2100 T.
According to requirements the sector or diameter measuring
function can be chosen. The measuring principle of the Laser
2100 S/R is based on a combination of three laser diodes as
light sources with a CCD-line sensor in one plane. The height
of stretched sector cables, which can be solid or stranded,
is defined from the position of the edges that define the
object. Even if the product turns up to ±15˚ the height is
accurately determined. The Laser 2100 S/R is appropriate for
the measurement of sector conductors with a cross section
of Amax=750mm2 (for 120°-sectors) and Amax= 500mm 2
(for 90°-sectors).
The outer diameter and ovality of round cables is also
calculated with an optical measuring principle. With the three
laser light sources in three planes and CCD-line sensors, the
outer diameter is calculated directly from the shadow image
with the help of advanced software. The gauge head is suitable
for round cables from 1mm to 100mm.

Based on ultra-high molecular weight PVC, Sunprene
Elastomers from A Schulman possess many rubber-like
qualities, while offering thermoplastic processing, recyclability,
and cost effectiveness compared with thermoset EPDM
rubber and traditional thermoplastic elastomers. They provide
exceptional tear and abrasion resistance, high flex fatigue,
and excellent low temperature brittleness. The materials
can be customised to meet a broad range of performance
requirements for wire and cable applications.
“Sunprene Elastomers are a high-performance, economical
alternative to thermoset EPDM rubber and traditional
thermoplastic elastomers,” said Lee Pfaffle, business manager,
engineered plastics. “On cost, processing and performance,
Sunprene Elastomers are an excellent solution for a variety of
wire and cable applications.”
Sunprene Elastomers are available in two series. The first
series is specifically formulated for extrusion applications and
has hardness ranges from Shore 35A to 85A durometer, and a
specific gravity range between 1.20 and 1.29.
The other series, designed for both injection moulding
and extrusion applications, has hardness ranges from Shore
57A to 65A durometer, and a specific gravity range between
1.22 and 1.27.
