“ ACID-FREE PROCESS FOR STEEL
ROD CLEANING & SURFACE
PREPARATION”
“New Way to Draw Steel Wire
in the 21st Century”
DCCD process features:
• Eliminates acid, borax and precoatings
• Zero energy consumption
• Direct drawing from bare rod with no
speed limitation, for H/C and L/C
• New Lubricant Viscosity Control
provides exceptionally adherent coating
• Adjustable lubricant residual
• Zero lubricant waste
• Recommended for severe drawing
applications (spring, rope, bead,
CO2 welding, PC strand, plating quality)
• H/C wire drawn at 18 m/s (3600 ft/min)
• Up to 8 times longer die life
• Exiting wire temp. 45°C (113°F)
• Greatly improved wire ductility

Nylon, from electric and fibre optic
cable manufacturer Tratos, is an
environmentally friendly alternative to
lead-sheathed cables for onshore power,
control and instrumentation applications
in the oil and gas industry.
These challenging environments call
for exceptional durability from all
equipment, especially cabling that may
be permanently open to the elements
or used alongside heavy duty, industrial
equipment. In response to the growing
market demand for more environmentally
friendly cables, Tratos has developed a
new lead-free barrier in its Nylon cable.
Nylon comprises three co-extruded
construction elements. The AluPE layer
features an aluminium coated tape,
applied longitudinally, that provides
a watertight seal. The High Density
Polyethylene (HDPE) sheath provides
resistance to inorganic chemicals such
as chlorine. The third element – the PA
sheath – provides resistance to organic
materials such as benzene.
Providing the same level of protection
against aggressive petrochemicals as
traditional lead-sheathed cables, Nylon
also features improved ease of handling
and installation.

Both Pourtier and Setic, members of the
Gauder Group, provide high quality rotating
machines (bunchers, stranders and cablers)
with the highest standards in design and
manufacturing.
Pourtier, based in Chelles, France, develops
comprehensive solutions for the production
of all types of high voltage and extra-high
voltage power cables, from overhead to
insulated, AC or DC type.
Its rigid stranding lines – stranding up
to 127 wires, copper, aluminium and
aluminium alloy – are specially designed
to produce a new generation of overhead
conductor made of trapezoidal wire (ACSS/
TW, ACCC) and also suitable for round
compacted cores for HV/DC cables, sector
cores for Milliken cables, regular overhead
conductor (ACSR, AAAC) as well as steel
wire armouring and copper wire screening.
The concentric stranding solution –
stranding of copper, aluminium and
aluminium alloy – is perfectly adapted
for 37 wires bare copper and aluminium
compacted strand production at high
speed. To complete the operation, drum
twister lines are the universal rotating
cabler/armourer for laying-up of copper or
aluminium conductors. Planetary lines are
available for steel wire armouring of fibre
optic and large submarine power cable and
umbilical cables.
Setic, of Roanne, France, offers complete
bunching/stranding solutions for the power
cable and automotive industry as well as
producing high quality special/LAN cables
with enhanced performances (in one step
or two steps according to product mix).
The range includes high speed double
twist bunchers for 7, 19, 37 wires (unilay
construction) or multiwires bunches,
large double twist stranders/cablers for
7, 19 wires strands and assembling of
conductors, double/triple twist twinners/
quadders, ideal for all pairing operations
for special/LAN cable; group twinners for
twinning and stranding of high-end LAN
cable in one tandemised operation; and
single twist cablers/stranders for cabling of
quality insulated cables.
