1.aluminum conductors are predominantly used in overhead line applications and for primary and secondary power distribution
the higher strength acsr conductors are used for river crossings, overhead earth wires, and installations involving extra long spans.the advantage of acsr is that it has high tensile strength and lightweight, which means over longer spans it needs less support. acsr is available with varying percentages of steel core to achieve different strength. one og the advantages of this conductor in particular is that the desiredstrength can be achieved without a loss of ampacity.
