Transformer Core Winding Machine
Our core winding machine can be classified into three series. Customer can choose the product based on the actual production demand.
- Heavy-duty Transformer
- Transformer
- Semi-automatic Toroidal
- Toroidal Amorphous Core/Nanocrystal
This range of product is applicable for winding cores for single phase or three-phase transformer (3-column or 5-column). The core section can be rectangle, trapezoidal or round. Composed of multi-head decoiler, feeding-rectifying-damping device, and main winding head (inverter control), the heavy-duty transformer core winding machine is applicable for winding toroidal cores for instrument transformer.
