? What is a double-layer foil winding machine and how does it work?
A double-layer foil winding machine is specialized equipment designed to simultaneously wind two layers of metal foil (copper or aluminum) onto a transformer coil. It uses independent dual-path tension control to ensure each layer is wound precisely and evenly.
? What foil materials and thicknesses are compatible with this machine?
The machine is compatible with copper (Cu) foil in thicknesses from 0.3mm to 2.5mm and aluminum (Al) foil from 0.5mm to 3.0mm, making it suitable for a broad range of applications.
? What are the available model options and their key differences?
Four models are available: SH-600, SH-800, SH-1100, and SH-1400. Differences lie in the supported foil width (up to 1400mm), maximum foil tension (up to 14,000N), and winding speeds.
? What welding methods does the machine support?
The machine supports both TIG (Tungsten Inert Gas) welding and cold pressure welding. The welding speed ranges from 0 to 0.5 m/min, ensuring high-quality foil joints.
? How does this machine improve production efficiency?
By enabling synchronous double-layer winding, the machine effectively halves the number of winding passes required. Combined with automatic feeding, it significantly reduces manual intervention and shortens the production cycle.
? Which industries is this machine best suited for?
It is widely used in medium/high-voltage transformer manufacturing, large-capacity reactor production, new energy power conversion systems, industrial high-power equipment, and railway electrical systems.
