Demonstration of
concentric technologies
In February, Setic and Pourtier invited
customers to a demonstration of their
concentric technologies, with three
machines under production conditions
as well as their ‘Quali2twist’ principle. The
demonstration was attended by cable
makers from three continents.
The 630 DIN bobbin production capacity of
the Concentric Tape Screening Head type
TEC 630-95-dc is more than 30 times the
one of pad on a tangential taping head.
This process is suitable for counter helix
or screen application for the manufacture
of LV, MV and HV, control and special
cables at high production speeds (up to
600 rpm). This head was demonstrated by
applying a copper tape (11mm x 0.10mm)
on a cable of diameter 8.80mm, with
30mm lay length, at 550rpm.
The Concentric Steel Wire Armouring
Head model TEC 630-SWA produces
SWA cables at speeds up to 500rpm and
reaches an extended capacity up to 18km.
During the demonstration six wires of
0.9mm diameter were applied around a
12mm diameter cable.
The Multiwire Concentric Strander type
COS1200-2 allows the optimising of
copper consumption and increases the
capacity of stranding line for power cables
(section 35-500mm² or more). Cables are
produced at speeds up to 500rpm (two to
three times more productive than a rigid
strander). It offers specific advantages:
short line length compare to conventional
concentric stranding line and driven
tension control improving process
reliability on the smallest wires. This
strander was demonstrated on stranding
of seven 1.96mm wires at 500rpm.
The ‘Quali2Twist’ stranding machine
TA 1000-Q2T, which is dedicated to bare
wire strand or sub-strand assembly for
very flexible cable, creates single twist
quality products (equivalent cable
quality and consistency compared with
single twist process) with double twist
productivity (twice as fast as single
twist process) thanks to the innovative
guiding system allowing final lay length at
closing die. The demonstration presented
stranding of an ultra-flexible strand made
of seven sub strands at 1500tpm.

You avoid them. Braude wants them!
Braude is a specialist manufacturer of non-corrodable heating
and cooling equipment for the highly corrosive liquids
typically found in plating, anodising and other chemical
processing operations.
“We are interested in the liquids and conditions other
suppliers would avoid; our expertise is in heating aggressive
and corrosive solutions that conventional equipment cannot
withstand”, said a company spokesman.
The company has comprehensive production, assembly and
testing facilities, and large raw material and finished goods
stocks, enabling orders to be processed quickly and efficiently.
A significant proportion of sales are for export.
All products are manufactured from high integrity chemically
inert fluoropolymers (Teflon™, for example), and have been
designed to ensure long life in aggressive solutions. ISO 9001
certification ensures that they are all manufactured to the
highest quality standards.
Polaris non-corrodable electric immersion tank heaters have been
used successfully for many years by the metal finishing industry.
Both Popular and Modular models are easy to install, can be
used vertically or horizontally, have high thermal efficiency
and feature a safety grounded/earthing system.
Braude has extensive experience of the solutions found in
electroplating and associated processes and is able to offer
sound advice to provide the most effective Polaris heater for a
particular application.
Heaters are available in ratings from 0.5kW to 18kW and are
unaffected by stray currents.
For temperature control of solutions Braude manufactures
the Thermaster temperature controller which is robustly
constructed, simple to operate and install, and has a clear
visible display.
It uses non-corrodable PT100 probes for reliability and
accuracy. The probes are deposit resistant and virtually
unbreakable.
Also available are the Levelmaster liquid level controller and
the Tankmaster dual temperature and level controller.
