Aluminium Bus Bars for power distribution give an economic advantage compared to copper bars due to the lower cost of aluminium and to a significant difference in the weight / volume.In fact aluminium bars weigh up to 70% less than copper bars, compared with a reduction in electrical capacity of only about 30%.The use of aluminium bars for carrying electrical current is therefore recommended in switchboards, distribution equipment and systems where there are no space problems, or where weight reduction is critical.Aluminium bars with different corners are available with many Thickness and many lengths.
