With more than 40 years of experience in the field of rolling and drawing
non-ferrous metals and power cable production, Trafco has always
succeeded in introducing new technology into the design, construction
and reconditioning of its range of machinery and equipment for the
manufacture of all types of wire, cable and flat wire rope. The relatively
small size of the company and the advantages of its method of
production enable it to construct, customise and improve production
lines rapidly.
The company’s principal
markets – the Middle East,
Africa, Latin America and
Europe – now account
for 90% of exports. Co-
operation with overseas
agents and the company’s
fast response times result
in profitable relations with
customers who have relied
on Trafco to improve and
expand their plant with
increased productivity for
decades. Important results
have been achieved in
large projects for the
implementation of new turnkey plants, where the client is provided with
a feasibility study and the know-how and supply and installation of the
plant, commissioning, personnel training and technical assistance for
maintenance and the supply of all spare parts.
The company has grown constantly over the years because it has
focused on its customers’ requirements, an inexhaustible stimulus for
innovation and organisational and technological improvement. Studying
and planning for future international requirements, the company pays
particular attention to wire drawing processes and is currently working
on innovative developments for cable production.

The very definition of wire
incorporates a reference to drawing
machinery: an elongated strand of
drawn metal. And the drawing process
is the silent partner to whatever else is
done to wire to ensure that it satisfies the
requirements of the end user. Crimping.
Stranding. Insulating. Jacketing. These
and every other downstream process
depend on wire of exact composition,
drawn to exact diameter.
While an elongated strand of metal
offers little margin for error, even so it
is governed by the same laws of physics
that operate everywhere. The skin
effect in electrical conductance – the
power loss at high frequencies when
current travels near the surface – is not
suspended because the ‘skin’ of a single-
strand wire is of microscopic thickness.
While perfection is much to ask, wire
happens to be a narrow, attenuated
product that must meet colossal
demands. Whether intended for an
application as fine as the gauze (from
the Persian: silk) on top of a Bunsen
burner, or as mighty as a coaxial cable,
wire must be perfectly drawn from its
first pass through die or draw plate –
reliably, repeatably, certifiedly.
Anything less would be a waste of
effort, material, time and money.
