LV coil winding machine
Low-voltage coil winding machine is specialized equipment for winding the low-voltage coils of transformers. In electrical equipment, the low-voltage side typically exhibits the physical characteristics of “low voltage, high current,” requiring the use of conductive materials with a large cross-sectional area to carry the high current. BEST™ low-voltage coil winding machine is a heavy-duty winding machine specifically designed to handle these high-strength, heavy-duty wires (round wire and flat wires).
BEST™ LV coil winding machine
BEST™ is a professional transformer lv coil winding machine manufacturer , dedicated to the research and development and manufacturing of winding equipment for distribution transformers and high-voltage transformers. It is renowned for its “high torque,” “high rigidity,” and “non-standard customization,” with its heavy-duty transformer winding machine and vertical winding machine accounting for 35% of the Chinese low-voltage coil winding market. In 2025-2026, BEST™ was recognized as one of Schneider Electric China’s best suppliers.

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™ low-voltage coil winding machine perfectly solves the problems of looseness, overlap, and uneven tension in the winding of thick and flat wires, thanks to its superior spindle torque, robust machine rigidity, and intelligent heavy-duty wire arrangement system. It is especially effective for complex processes involving winding large-section conductive materials such as single large-section round wires and thick flat copper wires, as well as winding multiple conductors in parallel. Through powerful mechanical drive and a precise control system, this equipment ensures that every turn of the heavy-duty coil is tightly and neatly arranged, making it an essential tool for building high-quality transformer core components.
