The TRANFOVIA Heavy Duty Transformer Coil Winding Machine is designed for factories where coil load, low-speed torque and mechanical stability determine equipment selection. It is available in 2-ton and 3-ton configurations for winding high-voltage and low-voltage transformer coils within the approved shaft, tooling and center-distance range.
Unlike automatic winding systems focused on conductor spreading or insulation feeding, this machine provides a robust spindle platform with mechanical gear selection and variable-frequency speed control. The 2-ton model delivers up to 2,000 N·m of torque, while the 3-ton model delivers up to 4,000 N·m.
Two load configurations. The 2-ton and 3-ton models allow the buyer to match the winding machine to the maximum approved coil weight and tooling load.
High low-speed torque. Maximum torque is 2,000 N·m on the 2-ton model and 4,000 N·m on the 3-ton model.
Two mechanical speed ranges. The low-speed range prioritizes torque and control, while the high-speed range supports lighter winding stages. Frequency control provides stepless adjustment within the selected range.
Adjustable tailstock. The center distance can be set to support different shaft lengths and coil axial dimensions.
Reversible turn counter. Forward and reverse counting with power-off memory helps retain the winding record after an interruption.
Compact machine footprint. Both models use a 3,850 mm long and 800 mm wide base, simplifying preliminary workshop layout planning.

1、What is the main difference between the 2-ton and 3-ton models?
They differ in rated load, maximum torque, speed range, standard shaft length, tailstock adjustment range and overall height.
2、Why is the maximum speed lower on the 3-ton model?
The 3-ton configuration is designed for greater load and torque, so its mechanical speed ranges are lower than those of the 2-ton model.
3、Does the machine retain the turn count after a power failure?
Yes. The counter supports forward and reverse counting with a power-off memory function.
4、Is this a fully automatic transformer coil winding machine?
No. Its primary purchasing value is heavy-duty load support, torque and mechanical speed control. Automatic spreading and insulation feeding belong to a different machine configuration.
5、Can it be used for both HV and LV coils?
Yes, provided the finished coil weight, tooling, shaft dimensions, winding speed and torque demand fall within the selected model range.
