Frequently Asked Questions
Q
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, reducing production steps while improving coil quality and consistency.
Q
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. This wide material adaptability makes it suitable for a broad range of transformer and reactor manufacturing applications.
Q
What are the available model options and their key differences?
Four models are available: SH-600, SH-800, SH-1100, and SH-1400. The primary differences lie in the supported foil width (100–600mm up to 300–1400mm), maximum foil tension (6,000N to 14,000N), and winding speed (0–30r/min for smaller models, 0–20r/min for larger ones), allowing customers to select the right capacity for their production needs.
Q
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, and the edge correction precision is ±0.5mm, ensuring high-quality and reliable foil joints throughout the winding process.
Q
Which industries and applications is this machine best suited for?
This machine is widely used in medium/high-voltage transformer manufacturing, large-capacity reactor production, new energy power conversion systems (inverters, energy storage), industrial high-power equipment, and railway electrical systems including traction transformers and auxiliary power supply devices.
Q
How does this machine improve production efficiency compared to single-layer winding?
By enabling synchronous double-layer winding, the machine effectively halves the number of winding passes required. Combined with automatic feeding and winding functions, it significantly reduces manual intervention, shortens the overall production cycle, and lowers labor costs — making it a highly efficient solution for high-volume transformer coil manufacturing.
