Frequently Asked Questions (FAQ)
Q
What foil materials are compatible with the SH series foil winding machine?
The SH series foil winding machine is compatible with both copper (Cu) and aluminium (Al) foil. Copper foil thickness ranges from 0.3mm to 2.5mm, while aluminium foil thickness ranges from 0.5mm to 3.0mm, covering a wide range of transformer winding requirements.
Q
What is the maximum foil width supported by the SH-1400 model?
The SH-1400 model supports a foil width of 300mm to 1400mm, making it the widest-capacity model in the SH series — ideal for large-scale transformer coil production.
Q
What welding methods does the foil winding machine support?
The machine supports two welding methods: TIG (Tungsten Inert Gas) welding and cold pressure welding. The welding speed is adjustable from 0 to 0.5 m/min, providing flexibility for different foil joining requirements.
Q
How does the correction system work on this foil winding machine?
The correction system uses photoelectric analog sensors that do not make physical contact with the foil edge. This non-contact design ensures a correction precision of ±0.5mm and is suitable for both thick and thin foil materials, reducing the risk of foil damage during operation.
Q
What industries and applications is the foil winding machine suitable for?
The foil winding machine is widely used in power transformer manufacturing (high-voltage, medium/low-voltage, and specialty transformers), industrial reactor and rectifier transformer production, as well as new energy applications including wind power, photovoltaic, energy storage systems, and EV charging pile transformers.
Q
Is the foil winding machine easy to operate and maintain?
Yes. The machine is controlled by a PLC system combined with a touch screen interface, allowing operators to set and monitor foil tension, layer insulation tension, coil parameters and winding status in real time. This design minimizes operational errors, reduces maintenance needs, and ensures stable, efficient production with minimal downtime.
