5Equipment is controlled by PLC and touch screen, less fault of whole machine, no friction noisy, stable working, 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: These are 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: These are designed for fast-charging charging piles and feature compact, high-power-density foil coils to meet the power needs of electric vehicles for rapid charging.
Frequently Asked Questions (FAQ)
Q1
What foil materials are compatible with the SH series foil winding machines?
The SH series foil winding machines support both copper (Cu) and aluminum (Al) foil. Copper foil thickness ranges from 0.3mm to 2.5mm, while aluminum foil thickness ranges from 0.5mm to 3.0mm. Both single-layer and double-layer winding configurations are available.
Q2
What is the maximum foil width and coil outer diameter supported?
The maximum foil width depends on the model: SH-600 supports up to 600mm, SH-800 up to 800mm, SH-1100 up to 1100mm, and SH-1400 up to 1400mm. The maximum coil outer diameter for SH-1100 and SH-1400 models is 1000mm.
Q3
What welding methods are available on this foil winding machine?
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, making it suitable for various foil joint requirements in transformer coil manufacturing.
Q4
How does the tension control system work on the SH foil winding machine?
The machine uses a motor-driven active tension supply method that maintains stable tension during winding, stopping, and foil returning processes. This advanced approach prevents foil loosening caused by tension loss, ensuring consistent coil quality throughout the entire winding cycle.
Q5
Is the foil winding machine suitable for both dry-type and oil-immersed transformers?
Yes. The SH series foil winding machine is designed for a wide range of transformer types, including dry-type power transformers (commonly used in high-rise buildings and subways) and oil-immersed power transformers (used in large outdoor substations). It is also applicable for specialty industrial transformers and reactors.
Q6
What control system does the foil winding machine use, and how easy is it to operate?
The machine is controlled by a PLC (Programmable Logic Controller) combined with a touch screen interface. All key parameters — including foil tension, layer insulation tension, coil dimensions, and winding status — can be set and monitored directly on the screen. This design ensures intuitive, accurate, and efficient operation with minimal maintenance requirements.
