Automatic HV Coil Winding Machine

Automatic HV Coil Winding Machine for Round and Flat Wire

The TRANFOVIA Automatic HV Coil Winding Machine is designed for transformer manufacturers that need automated control together with a wider conductor range. It supports enameled round wire as well as rectangular flat wire, making it suitable for high-voltage coil programs that cannot be handled by a round-wire-only winding system.

The machine accommodates round, oblong, oval and rectangular coils. Its maximum axial winding height of 1,200 mm and maximum coil outside diameter of 900 mm provide additional working capacity for taller or larger high-voltage coils used in distribution transformers, instrument transformers and electrical reactors.

Applications

This machine is best suited to projects where conductor flexibility and automatic control are the primary purchasing requirements.

• High-voltage transformer coils: Production of HV coils within the stated 1,200 mm axial and 900 mm outside-diameter range.
• Round and flat wire programs: Suitable for enameled round wire and flat wire used in different coil designs.
• Amorphous transformer coils: Applicable to automated winding of amorphous high-voltage coils.
• Instrument transformer and reactor coils: Supports multiple coil shapes used in mutual inductors and electrical reactors.
• Mixed production schedules: Useful when one production area must process round, oblong, oval and rectangular coils.

Main Features

• Round and flat wire capability. The conductor range covers enameled round wire from Φ0.3 to Φ4.0 mm and flat wire up to 3 × 12 mm, reducing the need for separate winding machines for these conductor types.
• Larger automatic winding range. A maximum axial coil height of 1,200 mm and outside diameter of 900 mm provide more working capacity than the compact 800 mm automatic model.
• PLC and servo control. The control system coordinates winding motion and speed settings to support repeatable operation across approved coil programs.
• Multiple coil geometries. Round, oblong, oval and rectangular coils can be produced when the correct shaft, mandrel and tooling are selected.
• Adjustable winding speed. The 0-280 r/min range supports low-speed setup, conductor connection and controlled production winding.
• Specified control components. The standard component list includes HIWIN linear guides and ball screw, Weinview touchscreen, Hpmont frequency converter, Delta PLC and Migge servo system.

Automatic HV Coil Winding Machine FAQs

1、Can the machine wind both round wire and flat wire?

Yes. The stated conductor range is enameled round wire from Φ0.3 to Φ4.0 mm and flat wire up to 3 × 12 mm.

2、What is the maximum coil size?

The maximum stated axial height is 1,200 mm and the maximum coil outside diameter is 900 mm.

3、Which coil shapes are supported?

The application range includes round, oblong, oval and rectangular coils.

4、Is this the correct machine for 2-3 ton coils?

This page is positioned around automatic HV winding and conductor flexibility. Projects driven primarily by 2,000-3,000 kg load capacity and high low-speed torque should be evaluated against the heavy-duty 2-3 ton winding machine.

5、What should be confirmed before ordering?

Provide the coil drawing, conductor specification, coil weight, winding tooling, insulation process, output requirement and factory utilities so the configuration can be checked before quotation.
