Frequently Asked Questions
Q What foil materials are compatible with the SH series foil winding machine?
The SH series supports both copper (Cu) and aluminum (Al) foils. Copper foil thickness ranges from 0.3–2.5mm, while aluminum foil thickness ranges from 0.5–3.0mm, making it suitable for a wide variety of transformer and reactor coil applications.
Q What is the difference between the SH-600, SH-800, SH-1100, and SH-1400 models?
The main differences lie in foil width capacity and maximum foil tension. The SH-600 handles foil widths up to 600mm with a max tension of 6,000N, while the SH-1400 supports widths up to 1,400mm and a max tension of 14,000N. Choose the model based on your coil size and production requirements.
Q Does the machine support both single-layer and double-layer winding?
Yes. All models in the SH series support both single-layer and double-layer foil winding. The synchronous double-layer winding capability is a key feature that significantly improves production efficiency and coil consistency.
Q What welding methods are available on the SH series foil winding machine?
The SH series supports two welding methods: TIG (Tungsten Inert Gas) welding and cold pressure welding. Both methods are available at a welding speed of 0–0.5 m/min, ensuring strong and reliable foil connections.
Q What industries and applications is this machine best suited for?
The SH series foil winding machine 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 — anywhere that requires precise, high-efficiency foil coil winding.
Q How precise is the edge correction system on the SH series?
The SH series features an automatic edge correction system with a precision of ±0.5mm. This ensures that foil layers are aligned accurately throughout the winding process, resulting in high-quality coils with consistent dimensions and minimal waste.
