Transformer Aluminium Foil 1070 with Round Edge
Product Description
1060 and 1070 aluminium foil for transformer winding have very high conductivity and thermal conductivity, their conductivity is up to about 60%IACS, and forming, welding and corrosion resistance are very good, so it can well meet the performance requirements of aluminum foil for transformer.
Haomei transformer aluminium foil can be used for variable transformer like low or high voltage transformer winding, high frequency transformer,step up or down voltage transformer etc. The alloy can be used to meet the minimum industry requirements for strip conductor, is closely controlled to assure smooth, substantially burr-free edges and strip-size avail-abilities are in capacities exactly equivalent to those of standard copper wire sizes.
Aluminum foil for transformer is a material used for main part of the transformer winding. As for a transformer, is composed of four parts: winding, core, fuel tank and insulating sleeve. Among them, because the winding way is different, foil winding transformers with different widths of aluminum foil strip winding appeared. In this case, in addition to the advantage of high conductivity, aluminum foil for transformer has a stronger resistance to short circuit and significantly improves the performance of the transformer because the end of winding is flat instead of the traditional copper wire. Besides, in practice, aluminum foil for transformer input cost is much lower than copper wire, high economy, coupled with the lightweight advantage of aluminum foil for transformer, for many years, has been the preferred material for transformer manufacturing design and use.
