Anodized Aluminum Foil Strip for Transformer

In recent years, 알루미늄 호일 스트립은 변압기 권선의 전도성 재료로 사용됩니다.. 모두에게 알려진 바와 같이, 구리는 구리 재료의 가격이 높기 때문에 구리 와이어 대신 많은 공장에서 널리 사용됩니다.. 알루미늄 전선의 단위저항은 64% 구리선보다 크다, this kind of substitution will increase the external dimension of the transformer. With aluminum foil strip instead of copper strip, it can not increase the size of the winding.

Moreover, aluminium belt winding copper wire winding than there are certain advantages: due to the relatively uniform winding section temperature, short axial force; the interturn capacitance along the winding winding distribution, increase the stability of Overvoltage on impact; and realize mechanization winding process. But the existing aluminum band winding, in the process of winding, the aluminum belt or synthetic film placed in the aluminum layer, as a turn insulation, with a prominent aluminum belt insulation, to ensure the insulation of the ends of the winding. This kind of insulating material has low pressure resistance, temperature resistance and winding process, which seriously affects the working performance and service life of the transformer.

The low-voltage winding adopts anodized aluminum foil strip for transformer with a thickness of 0.5—2.0 and a width of 400–800mm, 그리고 1 또는 2 layers are stacked together to form a circular ring.

The high voltage winding is made of anodized aluminum foil strip for transformer whose thickness is 0.2—1.0mm and the width is 50–100mm. It is round and round.

The anodized aluminum foil strip for transformer, is on alumium surface with the formation of Al₂O₃ film, Al₂O₃ film is one which can resist high temperature of 2000℃, and excellent insulating material, winding with aluminum layer, no longer need to clip tape or synthetic film as insulating material. Not only simplifies the production process, and winding the pressure resistance and heat resistance have been significantly improved, the performance and service life of the transformer are improved significantly.

The anodized aluminum foil strip winded transformer has the characteristics of high efficiency, low noise, safe operation, 등., and is a new product which is greatly welcomed by the customers and has remarkable social and economic benefits.
