A159 alloy conductors are used in power transmission and distribution lines for a wide voltage range (low to ultra-high voltage). These conductors have higher current carrying capacity and lower losses due to DC resistance. A159 conductors have high corrosion resistance, making them most suited for deployment in coastal regions.
● 26%-31% more current carrying capacity than ACSR of the same size, while maximum sag remains the same and working tension is lesser than that of ACSR.
● Resistivity is substantially lesser than that of ACSR/AAAC conductors, resulting in lower 12R losses.
● Higher corrosion resistance than 6201 alloy series (AAAC).
