Rigid Stranding Machine

Rigid stranding machine(Individual motor drive)

Introduction

This machine (with lumped loading / unloading for bobbins device) is suitable for producing large length,compacted round conductor of bare Al/cu wire, and ACSR, aluminum alloy wire and for producing com-pacted sector conductor with single core preforming,drawing and compacting process. The machine is driven by separate motor for the stranding cage and dual capstan wheel. connecting between cages and dual capstan is no hardware transmission system; the stranding pitch can be adjusted freely.

    Advantage

    Each cage and capstan are driven by separate motor, the pitch can be adjusted freely.

    With constant and even pneumatic and mechanical tension system for brake.

    Simple and advanced design, reliable quality and high speed rotation.

    Automatic stop system for wire breaking.

    With continuous pneumatic supply for rotate air package, durable sealing material.

    Dual capstan wheels, natural wire distribution for preventing abrasion damage of wire cores when stranding.

    Side or bottom side loading system by automatic operation, which enhance the efficiency and more convenient.

    Easy maintenance, simple operation, low noise and pollution.

    Dc or Ac variable frequency motor drives, process control stable and reliable performance.
