Aluminum foil strip wire is a common material for winding transformer, and with the development of electric power, there are more and more aluminum foil strip wire materials used in all kinds of transformers used in transmission and transformation power engineering system. The electric welding machine, general transformer, iron remover, electromagnet, whole current and other electrical equipment need aluminum foil strip wire. In the process of use, the surface of the material itself is not insulated. In use, a layer of insulation (such as an insulating varnish) or a layer of insulating paper must be applied to its outer surface. In this way, the following problems arise: 1. It is known to everyone that the temperature resistance and cost of the insulating material are in the production and use of electrical products. Important issues directly affect the electrical properties, performance and production costs of electrical appliances. At present, the temperature limit of the widely used insulation materials is under 120 degrees C. The insulation material above 120 C can not be widely used because of the high cost. Only in special electrical appliances, it is only used. 2, aluminum foil strip wire. Outsourcing insulation paper causes transformer winding volume increase, winding trouble, and this transformer is inefficient and energy consuming, so it is urgent to innovate.
The production process of anodized aluminum foil strip wire is used instead of the winding used by the transformer currently used. The electrical chemical method is used to make a layer of AL2O3 oxide film on the surface of aluminum foil, which can be used as a new oxide film aluminum foil (band), which can be widely used in transformer winding. The electrical chemical method is mainly composed of electrolysis liquid tank and alternating current anodization.

The product is easy to produce, low cost, temperature resistant, easy to use, simple in technology, good in product quality, easy to be popularized and applied, and has great economic value.

The anodized aluminum foil strip wire is made up of aluminum, aluminum, or aluminum strips by electrical chemical methods to form a layer of oxide film on its own surface. The oxide film is insulated and protected for aluminum, aluminum and aluminum. The outer surface forms a layer of oxide film aluminum wire, aluminum foil or aluminum strip called anodized aluminum foil strip wire.

The anodized aluminum foil strip wire surface directly produces a layer of 0.007-0.01mm thick oxide film AL2O3, the melting point of the oxide film reaches 2500 degrees centigrade, the pressure is above 180V, the absolute safety temperature is above 250 degrees C, the scraping, tensile, bending radius (that is, aluminum wire, the half diameter of aluminum foil bending), adhesion strength and mechanical strength all reach or exceed. Enterprise requirements.

The anodized aluminum foil strip wire, especially for electrical appliances with high calorific value or high working environment temperature. The aluminum oxide (strip) produced by oxide film has the advantages of high power factor, energy saving, labor saving, time saving and material saving. In conclusion, the invention has the advantages of simple technology, high temperature resistance, low cost and energy saving. It is the most economical new temperature resistant electromagnetic material at present. Its popularization and application has inestimable economic effect and social benefit, and opens up a new way of energy saving.
