Solid aluminium bars

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.

Solid aluminium bars

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.
