Traditional cable manufacturing equipment generally includes: pay-off machine, extruder, cooling water tank, traction machine, and take-up machine. The pay-off machine releases copper wire or other types of conductors, and the molten insulation layer is wrapped on the conductor through the extruder to form an insulation layer, which is then cooled and shaped, and then pulled into the take-up machine with the traction machine and wound on the reel.
