Frequently Asked Questions
Q
What foil materials are compatible with the SH-series foil winding machines?
A
The SH-series machines support 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 them suitable for a wide range of transformer and reactor coil applications.
Q
What is the difference between the SH-600, SH-800, SH-1100, and SH-1400 models?
A
The main differences lie in foil width capacity, coil outer diameter range, max foil tension, and winding speed. The SH-600 handles foil widths up to 600mm with a max tension of 6000N, while the SH-1400 supports up to 1400mm foil width and 14000N tension — ideal for larger, high-power equipment manufacturing.
Q
What welding methods are supported by these foil winding machines?
A
The SH-series supports two welding methods: TIG (Tungsten Inert Gas) welding and cold pressure welding. Both methods are available across all four models, allowing operators to select the most suitable process based on material type and coil requirements.
Q
How does the synchronous three-layer winding feature improve production efficiency?
A
The synchronous three-layer winding system allows all three foil layers to be wound simultaneously in a single pass, eliminating the need for repeated setups. Combined with automated feeding, this reduces manual labor by over 40% compared to traditional single or double-layer winding machines, significantly shortening production cycles.
Q
Is the SH-series foil winding machine suitable for high-voltage transformer coil production?
A
Yes. The SH-series is specifically designed for medium and high-voltage applications, including 110kV+ power transformers, high-voltage test transformers, and GIS supporting transformers. The reinforced structure and intelligent tension control ensure precision and stability even under demanding high-voltage coil winding conditions.
Q
What is the correction precision of the SH-series foil winding machines?
A
All models in the SH-series feature a correction precision of ±0.5mm. This high-accuracy edge alignment system ensures consistent foil positioning across all layers, which is critical for maintaining insulation integrity and dimensional accuracy in high-precision coil manufacturing.
