Cable, Wire and Extrusion

Until now, the removal of the residual moisture film from water-cooled insulated wire/cable and extruded products has been difficult to achieve effectively and consistently.

However, ACI’s systems are an innovative range that achieves both major running cost savings and vastly improved cable and wire drying efficiencies when compared to compressed air nozzle arrangements and other existing blower-driven devices available to the industry today.

Standard System

  • Line speeds up to 400m/min
  • 2 to 25mm product diameter
  • 3kW Multi Stage blower

High-Speed System

  • Line speeds up to 1000m/min
  • 0 to 4mm product diameter
  • 5.5kW Side Channel Blower

The problem:

The process of extruding insulating layers and jacketed covers over wires
typically involves conveying product through a cold water trough in order to
bring down extrusion temperatures. The removal of any residual moisture is
essential because if left wet, significant issues will occur with processes such
as product labelling and spark testing. Effectively and consistently drying cable
and wire has proven difficult and expensive. Because of this, manufacturers
have used a variety of configurations including homemade air knife systems;
various compressed air nozzle systems; air wipes and even sponges. All with
varying degrees of success but overridingly ineffective.

The solution:

By working closely with cable and wire manufacturers, ACI has quickly earned
a solid reputation for producing quality, engineered drying solutions suitable
for the cable and wire markets. ACI’s Systems are a collection
of blower-driven units that uses precisely controlled blower-driven air flow
that reduces noise, improves drying efficiencies and dramatically cuts energy
consumption. They operate by closely focusing powerful angled air jets against
the flow of the product. These air jets are opposing, and aim at the top and
bottom of the product to hold back the advancing residual moisture. This is
achieved by breaking the surface tension of the water, allowing it to gather and
puddle before the jets.
