Transformer Foil Winding Machine – Automated PLC-controlled equipment for precision coil production. Features hydraulic unwinding, two-stage tension & magnetic clutch. Reduces transformer loss 30%+. Request quote!
Product details
Our Transformer Foil Winding Machine is the specialized equipment for manufacturing transformer foil windings (also known as box-type coils). It utilizes copper or aluminum foil strips of varying thicknesses as conductors, with wide-band insulating material for inter-layer insulation and narrow-band insulating material for end insulation. The machine completes the entire winding process in a single operation, forming a wound coil while simultaneously performing lead welding on both the inner and outer sides and applying surface wrapping.
Key Features & Advantages:
PLC Automation & Control: Equipped with PLC automatic control and a variable-frequency stepless speed regulation system, ensuring precise operation and industry-leading performance.
Reduced Transformer Losses: Engineered to significantly reduce transformer losses.
Hydraulic Material Unwinding: Features a hydraulic expansion/contraction mechanism on the unwinding head for easy and labor-saving operation.
Precision Foil Tension Control: Employs a two-stage tension control system. Maintains accurate, consistent tension during forward winding, stopping, and unwinding, guaranteeing solid and compact coils.
Advanced Insulation Handling: Layer insulation paper tension is managed using an air shaft and magnetic powder clutch, enabling quick material changes and effortless tension adjustment.
