1250 Wire Bunching Machine stranding copper wire PVC wire Al wire
and below 7 wires conductor
- Introduction
This equipment is dedicated to twist aluminum and copper round
compress conductor.
This project contains a external rotation pressure die structure,
and provide the required traction used for compress conductor, when
the conductor compress, the take-up partof bundling machinewill
obtain, and have a special line way to reduce torque between
rotating traction wheel and take-up bobbin, can be ensure that
there is a good round conductor.
- Purpose & characteristic:
This machine is suitable forstrandingcopper wire ,PVC wire, Al wire
and below 7 stands conductor, mainly used for sectional area for
copper 50mm2,AL 70mm2.
The production efficient is 4.5 times compared withtubular machine.
This machine has appied a Chinese national patent, Patent No.: ZL
2010 2 0522064.5
