Foil Type Winding in Transformer

The foil type winding in transformer is mainly used for small and medium-sized transformers. 1060, 1070 and 3003 aluminum foil big rolls are usually chosen for the transformer winding. Learn more.
Transformer is a device that makes use of electromagnetic induction to change AC voltage. The main components are primary coil, secondary coil and iron core (magnetic core). The main functions are: voltage conversion, current conversion, impedance conversion, isolation, voltage stabilization (magnetic saturation transformer), etc.
The foil type winding in transformer is mainly used for small and medium-sized transformers with a capacity of less than 2000kVA. Its advantage is that it can increase the filling factor of conductive materials in the iron window, and the volume can be reduced. At the same time, the thermal conductivity of the radial direction of the winding is increased, the temperature gradient is low, and the thermal stability is good, thereby suppressing the hot spot temperature of the winding. And because the winding process only winds from one direction, there is no lateral movement, so it is easy to improve the mechanical strength, reduce the winding man-hours, and the structure is simple.
Aluminum foil for transformer is mainly used for dry and oil-immersed transformer winding. Aluminum foil ranges from 0.2mm to 3.5mm in thickness and 10mm to 1600mm in width. Aluminum coils are wound on insulating materials such as paper, kraft paper, polyester film or glass cloth. Aluminum foil like 1060 alloy has high conductivity, good corrosion resistance and beautiful appearance. It is an essential material in the production of transformers.
Aluminum foil has some outstanding properties such as high electrical conductivity, soft texture and light weight. Aluminum foil transformers have many advantages over traditional wire transformers, like the ability to operate at high temperatures , high electrical efficiency and reliability. Aluminum foil should be cleaned before being used in transformer windings to prevent dirt from entering the interior after winding operations are completed.
1060, 1070 and 3003 aluminum foil big rolls are usually chosen for the transformer winding. Because the production process of the product is relatively simple and the technology is relatively mature, it has a price advantage over 5000 series and 6000 series.
When foil winding, the aluminum foil must be tensioned to maintain a certain tension, and wound into a winding coil smoothly and flatly. The thicker the aluminum foil, the greater the tension required. The maximum tension of the foil winding machine is limited, exceeding the maximum tension of the machine is dangerous. Haomei Aluminum can strictly control the thickness of aluminum foil big roll to ensure that it meets your requirements.
