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 situations when tension is lost in winding.
-
★Turbine Shaft Speed Reducer: The winding speed reducer is a turbine shaft reducer, which keeps the main shaft auto-locked in both power-on and power-off status.
-
★Photoelectric Analog Correction System: The correction system uses photoelectric analog sensors with no contact with the foil edge, accepting both thick and thin foil materials.
-
★Intuitive Digital Control Panel: 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 performance 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), producing 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), producing low-loss, high-efficiency foil coils to ensure stable power supply to end users.
- ● Specialty power transformers: Including 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), whose 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 to 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), producing 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: Including 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 with 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 this foil winding machine?
This foil winding machine supports both copper (Cu) and aluminum (Al) foil materials. Copper foil thickness ranges from 0.3mm to 2.5mm, while aluminum foil thickness ranges from 0.5mm to 3.0mm, making it suitable for a wide variety of transformer coil production requirements.
Q
What are the available model options and their key differences?
There are four models available: SH-600, SH-800, SH-1100, and SH-1400. The main differences lie in foil width capacity (100–600mm up to 300–1400mm), maximum foil tension (6000N to 14000N), and winding speed (0–30r/min or 0–20r/min). Customers can select the appropriate model based on their coil size and production requirements.
Q
What welding methods does this machine support?
The foil winding 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, ensuring clean and reliable foil joint connections during the winding process.
Q
How does the correction system work and what is its precision?
The correction system uses photoelectric analog sensors that do not make contact with the foil edge. This non-contact design works with both thick and thin foil materials. The correction precision is ±0.5mm, ensuring accurate and consistent foil alignment throughout the winding process.
Q
Is this foil winding machine suitable for new energy applications?
Yes. This machine is widely used in new energy sectors including wind turbine box transformers, photovoltaic inverter transformers, energy storage converter (PCS) inductors, and charging pile transformers. It is capable of producing compact, high-power-density foil coils that meet the demands of modern clean energy systems.
Q
How is the tension controlled during the winding process?
The machine adopts a motor-initiative tension supply method, which maintains stable tension during winding, stopping, and foil returning phases. This advanced tension control prevents foil loosening caused by tension loss during operation. All tension parameters can be monitored and adjusted in real time via the PLC-controlled touch screen interface.
