The PWC system simultaneously performs drawn wire cleaning
and polishing, in-line with wire drawing machine at up to 12m/s
(2,400ft/min), in a totally green application.
Exceptional cleanliness obtained in glossy finish and plating
quality permits wire direct brass coating, copper coating,
galvanising, plating, Al and Cu cladding and wire cleaning prior
to heat treatment and coating applications including patenting,
annealing, painting, plastic coating, etc.
For a clean mirror reflective wire finish, for decorative
applications, the system can be used with a conventional
emulsion diluted at 3-5 per cent concentration.
The PWC incorporates new technology that enables normal
plant cold water to be converted into a unique cleaning
medium generating pressure wetting/contaminants extreme
pressure extrusion/hydrodynamic cavitations displace/and
contaminants flush out, used to clean drawn wire at high-speed
in a completely green application.
The PWC system effectively loosens and removes lubricant
residue from base material and is particularly recommended for
cleaning applications with wires drawn upon severe conditions
resulting in increased heat and burned lubricant tightly bound
to the wire surface and embedded in micro-cavities which are
further smoothly polished under high pressure, generated by the
unit, effectively separating lubricant residue from base material,
washing away dispersed contaminants, enabling wire exiting the
unit very clean of white-metal appearance with reflective finish
and totally dry.
The PWC system provides the ultimate combination of simplicity
and effectiveness: acid-free, caustic-free, without ultrasonic,
without chemicals, hermetically sealed zero-emission system, no
fume, no foam. Economical and environmentally friendly, the
system provides significant process savings in production of
clean wire. The PWC unit is compact and can be easily installed
on the finishing/last block of a wire dry drawing machine.

Ethernet cable standards
Energy chain and continuous flex cable expert igus® now
offers a full range of Ethernet chainflex® cables, qualified
for CAT 5, 6, 6A and 7 standards.
Each cable type has been rigorously tested for more
than 40 million strokes at the igus test facility in Cologne,
ensuring secure data transmission even under the highest
mechanical demands.
The special construction of the chainflex CAT 7 cable
guarantees reliability and integrity in continuous
flex applications. The braiding has been increased
substantially and overall shielding has 90 per cent optical
cover, which ensures high-level functionality, even after
millions of bending cycles.
The CAT 7 cable is flame retardant, as are all cables with
the abrasion-resistant TPE outer jacket. In addition, the
cable is UL / CSA, EAC and CTP certified and DESINA
compliant. The CAT 7 range is also suitable for use in clean
room environments and has DNV GL approval for energy
chain applications in offshore environments.
