The foil winding machine is suitable for winding foil coils of transformers and electrical appliances. Developed by referencing US similar equipment technology and integrating the company’s transformer equipment design-manufacture experience, it uses varying-thickness copper/aluminum foil as conductor. With wide insulating strips for interlayer insulation and narrow ones for end insulation, it winds coils in one pass, while welding inner/outer leads and wrapping the outer surface, supporting qualified coil production and being essential for transformer components.
