Current Transformer Winding Machine CT Coil Precision 0.02mm Automatic Toroidal Core Winder

Current Transformer Winding Machine CT Coil Precision 0.02mm Automatic Toroidal Core Winder

Product Overview

Our Current Transformer Winding Machine winds CT coils on toroidal cores with 0.02mm layer precision, ensuring uniform secondary winding for metering and protection current transformers.

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

Transformer Applications

This current transformer winding machine is purpose-built for current transformer winding machine coil production. Typical transformer applications include:

• Metering current transformer secondary coils
