the round excellent blank of copper cover aluminum attenuates flat through repeatedly stretching, straight Shandong is to finishing metallurgical binding, and total deformation will reach more than 84%.Its shortcoming is that drawing numbers is too much, rate of finished products is low, quality be cannot say for sure card, manufacturability is poor, promotes the use of so influence it. The basic, normal, high copper busbar row who is press-fitted extensive use in the electric power systems such as electrical equipment, switch cubicle, control board, bus duct, vacuum switching device and generating set, rectifier, transformer, motor windings, bimetal joint, crane runway, it has advantage such as conduct electricity very well, ampacity is big, resistivity is little, mechanical strength is big, Corrosion Protection is good.But also there are shortcomings such as cost height, scarcity of resources simultaneously, therefore on using, are very limited Though fine aluminium bus row cost is low, its ampacity is little, easily close erosion, high-quality demand is not satisfied in the easy hydrogenation in contact place, performance.A kind of copper coated aluminum bus bank of present domestic research and development comes instead of copper or the solid bus row of aluminium.Manufacture method is to be welded into than the big 7-8 of finished product sectional area doubly by the argon arc welded tube mill.
