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.
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.
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.
The machine supports copper foil (Cu) with a thickness range of 0.3-2.5mm and aluminum foil (Al) with a thickness range of 0.5-3.0mm.
It adopts a motor initiative supplying tension method which guarantees stable tension during foil winding, stopping, and returning. This prevents the foil from loosening when tension is briefly lost.
The machine supports both TIG welding and cold pressure welding, operating at a welding speed of 0-0.5 m/min.
It utilizes photoelectric analog sensors that do not make physical contact with the foil edge, ensuring a correction precision of ±0.5mm for both thick and thin foils.
It is primarily applied in power transformer manufacturing (high, medium, low-voltage, and specialty dry/oil transformers), industrial special reactors/transformers (filter, rectifier, and electric furnace transformers), and new energy/energy storage equipment.
Yes, the equipment is controlled by a PLC and a touch screen interface. All key parameters—such as foil tension, layer insulation tension, coil parameters, and winding status—can be set and monitored easily and intuitively.
