Transformer Coil Winding Machine

There are different transformer coil winding machines in different capacity and configurations.
Automatic Coil Winding Machine (with wire traversing device)
Transformer Coil Winding Machine

This transformer coil winding machine is suitable for winding HV coils in round or rectangular shape for 30-2500kVA distribution transformers.

It consists of main winding device, auto wire traversing device , interlaminar insulation feeding device, tension-adjustable wire pay-off stand, pneumatic system, PLC & servo control system, etc.

This machine is of high automation, complete functions, and powerful dynamic force. It can promise the axial tightness and latitudinal compactness and so it is especially suitable for winding rectangular coils.

1. Max. coil outer diameter: less than 600mm
2. Axial height: less than 700mm
3. Diagonal length of rectangular coil: max. 1000mm
4. Weight of coil: max. 500kg
5. Suitable wire: flat wire max. 3x12mm; lacquered round wire diameter 0.3-3mm
6. Winding speed: 0~200rmp

Horizontal Coil Winding Machine with Flexible Compacting Device

This kind of horizontal coil winding machine is used for winding coils of big capacity transformers and reactors from 5 tons to 35 tons!

This machine can be equipped with vertical and horizontal compacting device and so the windings will be more compact and even, ensuring the quality of winding coils.

Applied with advanced electronic counter which can count both positive and reverse turns, our equipment also comes with power-off memorizing function.

Vertical Coil Winding Machine

This machine is special for winding coils for high voltage and super high voltage transformers. The chuck can raise/drop according to the height of coil so as to keep the working height.
This machine is inverter control, with stable start-up, low noise and easy operation.
It is equipped with electronic counter which can reduce turns when reversing. It can automatically stop at pre-set turns.
