A CNC Parallel Winding Machine for Voltage Transformers is an automated winding machine specifically designed for simultaneously winding multiple coils in parallel. It is primarily used for the production of high-precision coils for voltage transformers (PT/VT), instrument transformers, and small transformers.
It differs from ordinary CNC winding machines in that:
it can wind multiple conductors simultaneously (in parallel), such as 2, 3, 4, etc.
This results in multi-strand coils arranged in parallel, improving the coil's current-carrying capacity and insulation performance.

Our Solution
① Closed-loop tension (0–200g, error ≤3%) – Solves the problem of instability in fine wire
Utilizes a digital tensioner, unaffected by spool allowance.
Even winding 0.1mm wire will not result in loose layers or breakage.
② Precision wire arrangement system (wire arrangement error ≤0.01mm)
Servo-controlled wire arrangement rod automatically corrects deviations.
Improved repeatability of inner diameter, width, and layer height, significantly reducing batch deviations.
③ Servo spindle (smooth at low speed, no jitter at high speed)
Low speed is used for starting fine wire, high speed is suitable for winding thicker wire.
Reduces strain and axial vibration, resulting in tighter winding.
④ Quick model switching (clamp change completed in 2–3 minutes)
Suitable for factories producing multiple varieties in small batches.
Reduces downtime and maintains production line rhythm.
⑤ Stable structure (entire machine is made of steel frame)
Long-term continuous operation is less prone to cumulative errors.
Multiple customers have reported that the dimensional error has remained within ±0.02mm even after a year of continuous operation.
