Wire & Cable ASIA – September/October 2013
With the Preheater 6000 TC (TC -
Temperature Control), Sikora offers a
solution for a precise conductor
preheating, the basis for high-quality
cable production.
The Preheater 6000 TC is positioned
before the extruder and preheats the
wire by means of inductive heating up to
200°C. A controlling module controls the
power of the Preheater 6000 TC
depending on the conductor material,
the conductor dimension, the line speed
and the desired temperature.
A non-contact infrared camera takes the
temperature inside the Preheater.
With the approach of the direct
integration of a wire temperature
measurement in the Preheater and the
feedback to its power control, it is
assured that the wire temperature is
always at its desired level. The Preheater
is available for a product diameter of
0.32 to 2.8mm (0.08 to 6mm²) and
applicable for new lines as well as the
retrofitting on existing lines. The system
comes with all common interfaces such
Ethernet, Profibus and Profinet as well
as analogue ports.
Initially developed for Sikora’s Preheater,
the Wire-Temp 6000 is also now
available as a standalone version and for
retrofitting to existing preheaters. The
Wire-Temp 6000 determines the
conductor temperature independently
from the cross-section, the material, the
line speed and the surface structure of
the conductor.
A big advantage over conventional
systems is that the temperature
measurement is made by means of a
non-contact thermal image sensor in an
infrared camera, which detects the
conductor and provides accurate
measurements with no need for
calibration. The Wire-Temp 6000 is
available for product sizes from 0.1 to
10mm and from 0.15 to 100mm.
Various communication interfaces are
available for the transmission of the
measuring values to a Sikora processor
system, the line control or a laptop. The
universal interface module for
connections to RS485, RS232, Profibus
DP or industrial field buses such as
CANopen, Ethernet/IP, DeviceNet,
Profinet IO fulfils the demand. The
interface module and all connection
plugs are fully sealed for protection
against water, dirt and mechanical
damage.

Category 8 for data
Datwyler has developed ‘CU 8203 4P’,
a compact S/FTP AWG23 cable which
complies fully with the anticipated
requirements of the new Category 8.2
as specified in the ISO/IEC draft.
The new international standards for
Category 8 copper cable and
balanced cabling systems for 40
Gbit/s are currently being developed
as Draft Standards IEC 46C/976/NP
and ISO/IEC TR 11801-99-1.
Unlike the proposed standards for
symmetrical Category 8 data cables
discussed a few years ago, the sole
use foreseen by today‘s international
standardisation bodies is in data
centres with a maximum limiting
frequency of 2 GHz.
Standard ISO/IEC TR 11801-99-1
defines a point-to-point connection
between active devices at a maximum
distance of 30 metres, comprising 26
metres of installation cable and 2
metres of patch cable on either side.
Such a connection can replace
expensive fibre optic and twinax
cabling in data centres.
