Large Power Transformer Coil Winding Machine 10000kVA HV LV Winding Heavy Duty CNC

Product Overview

Our Large Power Transformer Coil Winding Machine handles HV and LV coils for power transformers up to 10000kVA, featuring heavy duty CNC control, high torque drive and rigid tailstock for large diameter windings.

Key Features

• Transformer Dedicated Design: Purpose-built for transformer coil winding with dedicated tension, traverse and layer control
• Automatic Tension Control: Constant wire tension from empty bobbin to full coil prevents layer slippage
• CNC / PLC Control: Programmable winding parameters for repeatable transformer coil quality
• Gearbox Drive: Rare earth aluminum alloy worm gear with self-locking, stable braking and low noise
• High Winding Precision: 0.1 turn positioning accuracy for consistent transformer electrical performance
• Heavy Duty Construction: Rigid bed, tailstock and faceplate designed for transformer coil loads
