A cable manufacturing facility requires skilled labor to operate the machinery involved in the actual production of the cables. Entry-level machine operators are often brought in to run equipment including extrusion systems, cablers, twinners, bunchers, cord twisters, irradiators, and braiders, while more experienced workers are brought in to handle utilities. Utility technicians must have a current boiler certification and have experience with building safety systems including fire control equipment and heater and boiler systems.
Extrusion Systems – Extrusion equipment bonds plastic coating to the metal components of the cable. This can be done as a straight extrusion where the plastic bonds directly to the cable or in a jacketing process where the individual strands of wires are sealed separately.
Cablers – Cabling equipment twists two or more conductor pairs into a cable bundle.
Twinners – Twinning machines complete a junction of two sets of jacketed wires. This process is very common in household appliances but not regularly used in industrial applications.
Bunchers – Bunchers tape individual jacketed wires together and add an EMI/RFI shield to the conductor groupings.
Cord Twisters – Cord Twisters twist two conductors together to cancel out electromagnetic interference from unshielded sources. The tighter the twist is the more effective the cancelation but the shorter the effective length of the cable.
Irradiators – An Irradiation operator uses high-energy electric pulses to crosslink the plastic molecules used in the jacketing process to improve temperature resistance, increase tensile strength, and give better solvent and cut through resistance.
Braiders -- Braiders apply a shield of copper wires over the sheathing of the cables to prevent energy loss and increase data security.
