SJ90+60 Cable Co-Extrusion Line For Nylon, PVC, PE, PE, XLPE

1. Application:

This unit is suitable for wrapping PVC, PE, PE, XLPE, low smoke and halogen-free thermoplastic cable materials by hot extrusion method for wire and cable sheath. The 80 and 60 machines adopt 1 + 1 coextrusion mode to manufacture double-layer building line or civil cable, as well as to produce large cross-section building cable.
