Teknomega have created a free to download software for calculating and selecting the most suitable busbar for your application. Find out more here.
Solid aluminium bars use Aluminium type EN-AW 1350 A and have the following technical properties; a tensile strength of 250N/mm2, a resistivity of 0.0172Ωmm2/m, and a density of8.9kg/dm3.
Aluminium busbar for power distribution gives an economic advantage compared to copper bars due to the lower cost of aluminium and to a significant difference in the weight / volume.
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.
