SXL Automotive Wire Extrusion Line

SXL Automotive Wire Extrusion Line

SXL cable (Cross Linked Polyolefin insulated cable) is a high-temperature automotive wire under the American standard (SAE J1127) system, mainly used in high-temperature areas such as engine compartments.

The SXL automotive wire extrusion line is a specialized equipment designed for producing high-temperature cross-linked polyolefin (XLPO) automotive cables that comply with SAE J1127 standards. It is suitable for extreme temperature environments such as engine compartments and exhaust systems.

Composition of Production Line

The SXL automotive wire extrusion line mainly includes the following core equipment:
Pay off Stand: Release copper conductors to maintain stable tension.
Preheating Unit: Heat the conductor to improve insulation adhesion.
Extruder: Melt PVC 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.
