The line is mainly used to manufacture aluminium and aluminium alloy stranding wire with big length and big cross section, aluminium stranding wire with steel core, copper stranding wire and insulated strand wire for wire and cable factory. Also can use to strand and compress sector shaped conductor. Mechanism is high, auxiliary function is full, content of spool is large, productivity is high, which is the ideal equipment to manufacture all kinds of stranding wires without back-twist. In addition, the line adopts integral loading bobbin at sides, floor space is small, loading position is accurate. The machine uses mechanical transmission, has good synchronism, expeditious and convenient maintenance.
