Advantages
- ⚡ Motor Initiative Tension Control: Adopting motor initiative supplying tension advanced method, stable tension is maintained during foil winding, stopping and foil returning. It can avoid loosen situation when the tension is lost in winding.
- 🔒 Auto-Lock Speed Reducer: Winding speed reducer is a turbine shaft reducer — it keeps the main shaft auto-locked whether in power-on or power-off status.
- 🎯 Photoelectric Analog Correction System: Correction system uses photoelectric analog sensors that do not contact the foil edge, making it compatible with both thick and thin foil materials.
- 📊 Intuitive Touch Screen Display: Foil tension, layer insulation tension, coil parameters, winding status and other data can all be set and displayed on screen — easy to operate, accurate and intuitive.
- 🤖 PLC & Touch Screen Control: Equipment is controlled by PLC and touch screen, resulting in fewer faults, no friction noise, stable working and high working efficiency.
Application of Foil Winding Machine
⚙️ Applied in the Field of Power Transformer Manufacturing
- ● High-voltage power transformers: Used in 110kV and above power transmission and transformation systems (such as substations and inter-regional power grids), these transformers produce high-voltage windings with copper/aluminum foil conductors to meet high-voltage, low-loss power transmission requirements.
- ● Medium- and low-voltage distribution transformers: Suitable for 10kV and below distribution networks (such as urban power grids and industrial park distribution), these transformers produce low-loss, high-efficiency foil coils to ensure stable power supply to end users.
- ● Specialty power transformers: These include dry-type power transformers (used in fire-resistant environments such as high-rise buildings and subways) and oil-immersed power transformers (used in large outdoor substations). Their foil windings must be wound using this equipment.
🏭 Applied in the Field of Industrial Special Reactors / Transformers
- ● Filter reactors: Used in high-power industrial applications such as steel and chemical industries, they filter grid harmonics and protect precision equipment. Their foil windings require high insulation strength and overload resistance.
- ● Rectifier transformers: Suitable for industrial production lines requiring DC power, such as electrolytic aluminum and electroplating. High-current-resistant foil coils are wound to ensure stable operation of the rectifier system.
- ● Electric furnace transformers: Used in industrial furnaces (such as arc furnaces and induction furnaces), they produce foil windings capable of withstanding short-term high loads to meet the power needs of high-temperature smelting.
🌱 Applied in the Fields of New Energy and Energy Storage Equipment
- ● New energy transformers: These include wind turbine box transformers (connecting wind turbines to the grid) and photovoltaic inverter transformers. Their foil coils must withstand harsh outdoor environments (low temperatures, wind and sand) and exhibit low losses.
- ● Energy Storage Converter (PCS) Inductors: Used in energy storage power plants to wind foil windings for filter and boost inductors in energy storage systems, ensuring efficient conversion between energy storage and release.
- ● Charging Pile Transformers: Designed for fast-charging charging piles and featuring compact, high-power-density foil coils to meet the power needs of electric vehicles for rapid charging.

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.
