As an independent wire and cable
manufacturer, Concept Cables Ltd is
committed to providing solutions for a
whole spectrum of industries across the UK.
In addition to its standard range of wires
and multicores, the company offers the
ability of manufacturing products designed
tomeet customers’specific requirements.
Concept Cables is dedicated to
continuous quality improvements in all
areas. This includes ongoing investment
in the latest manufacturing and test
equipment to ensure the company
can meet the high quality and service
demanded by its customers.
One of the main problems the company
has recently overcome is the removal
of the residual moisture film from
water-cooled insulated cable products
during production.
The removal of this moisture film from
extruded products proved inherently
difficult to achieve and the previously
employed compressed air nozzles were
inefficient at drying the wire/cables and
costly to run.
However, ACI’s new LINE-Dry system
appears to solve this problem whilst
at the same time achieving significant
savings in energy costs. Compared to
the original compressed air systems, it
is estimated that ACI’s blower-powered
wire/cable drying system can give up to a
10-fold reduction in energy cost savings,
which potentially equates to savings of
thousands of pounds each year.
ACI’s blower powered LINE-Dry system can
handle products up to 25mm in diameter
at speeds of 500m/min. The blower is
an ACI variable speed ‘Multi-Stage’ unit
controlled via a speed controller, which
gives flexibility to accommodate different
products and line speeds.
Two versions are available, one with the
dryer heads enclosed to contain displaced
moisture, and one which is an open unit.
With both versions, the blower and speed
controller are mounted on legs and
enclosed in an ABS plastic enclosure to
prevent moisture ingress. Air is delivered
at up to 2.8psi (80" SWG) at speeds of
8,800m/min (28,900ft/min) at 80oC.

CEMSA has recently launched onto
the market a new family of multi-head
resistance welding machines named “GRG
– MPS”.
This new series is dedicated to the
welding of stainless steel or carbon
steel wire panels, both basic and special
ones, like those used as shelves in
supermarkets.
The panels accepted by the machine
can be composed by long and cross
wires of different diameters as well as
by cross wires wires on longitudinal
bearing bars.
The machine can operate by a shuttle
tooling, either along the length-wise axis
(parallel to the multi-heads) and/or along
a 90° axis, perpendicular to the front, like
in integrated systems.
A similar machine can be offered
equipped with a pallets re-circulation
shuttle, with automatic loading and
unloading, as well as with automatic wires
feeder (hopper).
Heads can be 4, 6, 8, 10, or even 12
and 16, each fed by an AC transformer.
Otherwise with two AC transformers,
working in parallel and located besides
the heads. This last arrangement is
convenient for medium productions,
where the mechanical cascade is within
an acceptable time frame.
45-60 kVA is the rating of the transformers
fitted to each head, whilst 250 kVA is
the suggested rated power of the two
transformers working in parallel.
A more advanced alternative is the
version with the medium frequency
(1,000Hz) power package, which
is recommended wherever energy
consumption is an issue.
