Aluminum foil wound transformers and reactors have been widely used in many power electronics industries, such as EPS, rail transportation, new energy and so on. In the field of transformers and reactors, aluminum foil wound transformers have been widely promoted and applied in the industry because of their excellent cost performance. For example, almost all the inverter transformers used in high-power uninterruptible power supply (UPS) in the market have been changed from copper to aluminum foil wound.


 
The aluminum foil for reactors inductors specially developed by Signi Aluminum Co., Ltd. has a conductivity of more than 60%, no burr at the edge, and paper can be sandwiched in the middle to protect the surface of aluminum plate from injury during transportation and use. It has been rated as a high-quality supplier by many transformer factories at home and abroad, mainly Toshiba, Siemens, Schneider, etc.
 
Aluminum foil for reactors inductors developed by Signi Aluminum Industry Co., Ltd. has common thickness of 0.2-4.0mm, width of 20-500mm, and common inner diameters of 305mm, 405mm and 505mm.
