Frequently Asked Questions
Q
What foil materials are compatible with this double-layer foil winding machine?
The machine is compatible with 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 range of transformer and reactor manufacturing requirements.
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 foil width capacity (600mm up to 1400mm), coil outer diameter range, and maximum foil tension (6,000N to 14,000N), allowing customers to select the best fit for their production scale.
Q
What welding methods does the machine support?
The machine supports two welding methods: TIG (Tungsten Inert Gas) welding and cold pressure welding. Both methods ensure strong, reliable joints suitable for high-performance coil applications.
Q
Can the machine wind both single-layer and double-layer coils?
Yes. The machine supports both single-layer and double-layer foil winding modes. The synchronous double-layer winding capability is one of its core features, enabling simultaneous production of two layers to significantly improve manufacturing efficiency.
Q
What industries or applications is this foil winding 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.
Q
How precise is the edge correction system on this machine?
The machine features an automatic edge correction system with a precision of ±0.5mm, ensuring consistent foil alignment throughout the winding process. This precision control is critical for producing high-quality coils with uniform layer distribution.
