THE Machines has received an order for a plant to produce
submarine cables with optical fibres with sleeveless continuous
length of up to 120km formed and welded tubes. The future
target is to provide a single length of some 240km.
The production lines are designed to meet these challenges and
are composed of the following main core components:
•
One fibre optic steel tube production line for up to 48 fibres.
The lines are being designed for a production speed up to
30m/min and a dial-in adjustable and controlled fibre excess
length of 0.1 to 0.5%. (1 to 5% – per mille)
•
One production line for the sheath over the steel loose tube
(which is available at the customer’s plant)
•
One armouring and welding line to apply a layer of
reinforcement elements and to form and butt weld a copper
screen over the cable
Since the armouring line is equipped with 630mm diameter
spools it is necessary to stop the production line to re-load the
machine. A unique in-line system has been developed allowing
the welding process to be stopped and restarted without losing
any welding seam quality or weld seam integrity.

Celebrating 40 years, DeWAL Industries
designs and manufactures PTFE and
UHMW-PE films and pressure sensitive
tapes. Materials are produced using
proprietary skiving equipment and tight
quality control in the engineering and
production facility in Narragansett, Rhode
Island, USA.
With knowledge and experience in
polymer chemistry and compounding,
DeWAL has developed a family of high
quality PTFE custom thin films used for
abrasion resistance, low friction and
insulation.
DeWAL films may be filled, bonded,
sintered or porous. Typical applications
include EMI shielding, medical device
construction, wire and cable, and
automotive assemblies.
DeWAL’s design teams have the ability to
work with engineers to customise taping
solutions including colour clarity, specific
run lengths and narrow widths.
In addition to extruded unsintered PTFE,
low-density PTFE and sintered skived
PTFE, DeWAL can provide fluoropolymer
laminates with dissimilar materials to
custom specifications.
Proprietary technology enables the
manufacture of these films to a precise
thickness. DeWAL Industries’ stringent
process
and
design
capabilities
ensure DeWAL’s place as a supplier
in all segments of the wire and cable
industry.
DeWAL Industries has recently introduced
its newest packaging put-up for the PTFE
film used in wire wrap. Solid Pack® allows
for the largest amount of material to be
wound onto a single spool.
Solid Pack spools payout more smoothly
compared to traditional packaging,
eliminating breakage.
These
long
lengths
promote
extended production runs, increasing
manufacturing
efficiencies
which
are demanded in current economic
conditions. These spool configurations are
requested most often in aerospace wire
manufacturing where narrow widths and
extended runs are the norm.

PWM’s best-selling M101 cold welder and
other manually operated models from its
comprehensive range will be in action at
Booth 104 at this year’s IWCS in Rhode
Island, from 9
th
to 12
th
November.
Represented by Joe Snee
Associates, exclusive dist-
ributor for PWM’s machines,
spares and dies in the
USA and Canada, visitors
are
invited
to
watch
demonstrations of the cold
welding
technique
and
try out the machines for
themselves.
The versatile M101 cold
welder for bonding copper
wire 0.04" to 0.141" (1mm
to 3.6mm) and aluminium
0.04" to 0.197" (1mm to
5mm) is also commonly
used to weld profiles and strips for
armouring lines.
Low maintenance and simple to operate,
the M101 can be used either on a
workbench
or
supplied
with a trolley, enabling
the operator to wheel it
quickly to the work area,
saving effort and reducing
downtime.
PWM’s smaller BM10 and
BM30 manual welders are
robust, reliable machines,
designed for non-ferrous
wire and strip 0.0039" to
0.071" (0.1mm to 1.8mm).
They can also be used on a
workbench or supplied with
a trolley. The M10, M25 and
M30 hand-held models will
weld copper/aluminium wire 0.0039" to
0.071" (0.1mm to 1.8mm).
Comfortable to hold and quick and easy
to use, they are suitable for welding wire
breaks in confined spaces.
PWM’s range also includes air/hydraulic,
electro/hydraulic, pneumatic and electro/
pneumatic powered cold welders, for wire
and rod up to 25mm (0.984") copper and
30mm (1.181") aluminium.
PWM’s cold welding equipment is
designed and made to high standards in
PWM’s British workshops.
Dies are individually hand-made in
matched sets, in standard or custom sizes,
to suit round or profile wire.
