Instrument Transformer Winding Machine 0.02mm Wire Accuracy Automatic Coil Winder

Instrument Transformer Winding Machine 0.02mm Wire Accuracy Automatic Coil Winder

Product Overview

Our Instrument Transformer Winding Machine produces metering and protection instrument transformer coils with 0.02mm wire accuracy, ensuring ratio consistency for CT and PT applications.

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
