Frequently Asked Questions

Q
What foil materials are compatible with the double-layer foil winding machine?
The machine is compatible with both copper (Cu) and aluminum (Al) foils. Copper foil thickness ranges from 0.3 to 2.5mm, while aluminum foil thickness ranges from 0.5 to 3.0mm, making it suitable for a wide variety of transformer and reactor coil production requirements.
Q
What is the maximum foil width supported by the SH-1400 model?
The SH-1400 model supports a foil width range of 300 to 1400mm, making it ideal for large-capacity transformer and reactor coil winding applications that require wider foil materials.
Q
What welding methods are available on this foil winding machine?
The machine supports two welding methods: TIG (Tungsten Inert Gas) welding and cold pressure welding. Both methods ensure reliable foil joint quality, with a welding speed of 0–0.5 m/min and a correction precision of ±0.5mm.
Q
Can the machine wind both single-layer and double-layer coils?
Yes. All models (SH-600, SH-800, SH-1100, SH-1400) support both single-layer and double-layer foil winding. The synchronous double-layer winding capability is a key feature that significantly improves production efficiency compared to traditional single-layer winding machines.
Q
What 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 converters), industrial high-power equipment, and railway electrical systems including traction transformers.
Q
How does the dual-path tension control system improve coil quality?
The dual-path independent tension control system manages each foil path separately, ensuring consistent and uniform tension throughout the winding process. This results in even layer distribution, improved dimensional accuracy, and reduced risk of foil deformation or misalignment, ultimately delivering higher coil quality and consistency.
