Automotive Low-voltage Cable Extrusion Line
The automotive low-voltage cable extrusion line is the core equipment for manufacturing automotive low-voltage cables, which is used to evenly wrap insulation or sheath materials (such as PVC, XLPE, TPE, etc.) on the surface of conductors to form complete wires and cables. The process directly affects the electrical performance, mechanical strength, and environmental adaptability of the cable.
Composition of Production Line
The automotive low-voltage cable extrusion line mainly includes the following core equipment:
Pay off Stand: Release copper/aluminum conductors to maintain stable tension.
Preheating Unit: Heat the conductor to improve insulation adhesion.
Extruder: Melt PVC/XLPE and evenly coat the conductor.
Cooling Tank: Segmented cooling and shaping insulation layer.
Haul off: Control the speed of the production line.
Take-up Reel: Automatic winding of finished wires.
Testing Equipment: Spark tester, laser diameter measuring system, etc.
Process Flow
Pay-off → Preheating → Extrusion coating → Cooling and shaping → Spark detection → Printing → Take-up.
