BRJ Digital foil winding machine, special equipment used for transformer foil winding production, is produced by (copper or aluminum) conductive materials. The device is newly developed by the company according to full understanding of the actual use of transformers based on high quality and usefulness of winding transformers. The product has high quality and efficiency with simple and reliable operation.
Unwinding brake applies tension, the tension is stable and the static and dynamic tension is consistency, it is controlled by pneumatic components. Foil tape and insulation tape are applied with constant tension no matter it is winding or backing. In order to avoid uneven tightness coil by losing tension, the air pressure can be stepless adjusted, which ensure that the entire process of winding tension is stable.
