HV coil winding machine
High-voltage coil winding machines are specialized industrial equipment used in the power transformer manufacturing industry for winding high-voltage coils in transformers. BEST™ is a professional manufacturer of transformer hv coil winding machines, covering a full range of semi-automatic, fully automatic, heavy-duty, and vertical models. With high-precision CNC winding and highly sensitive constant tension control, BEST™ eliminates the risk of radial deformation and insulation breakdown in high-voltage coils.
BEST™ HV wire winding machine
BEST™ hv coil winding machines have been deployed in 46 countries and regions worldwide, with over 150+ machines delivered to 52+ transformer manufacturers. While our equipment has withstood the test of the market, our technical team has gone deep into the high-voltage coil winding production lines of transformer manufacturers to understand the actual production needs of customers. We then standardize the mechanical structure and software of the equipment, modularize the personalized functions, and realize flexible non-standard customization to meet the hv coil winding customization needs of different transformer manufacturers.

BEST™ Tips
If the transformer voltage level is >35kV, please refer to our heavy-duty transformer winding machine or vertical winding machine. If the transformer voltage level is <35kV and the single-sided current is >200A, please refer to our multi foil winding machine. You can also contact our technical engineer Mr. Robin for pre-sales support.
features
BEST™ high-voltage wire winding machine features a unique design in its mechanical structure and control algorithm. The machine body utilizes a single-piece cast iron bed, equipped with a high-rigidity electric locking tailstock to lock the spindle radial runout to the micron level. For multi-strand winding operations, BEST™ has developed an independent intelligent tension pay-off system, coupled with an advanced wire-laying compensation algorithm. This provides independent and precise servo reverse tension for each parallel conductor while achieving a tight, uniform arrangement of fine wires with an accuracy control of ±0.01mm.
