AL-59 alloy conductors are manufactured from Al-Mg-Si (aluminum-magnesium-silica) rods. The conductor comprises of an inner core and concentrically arranged strands forming the inner and outer layers of the conductor. In view of development of new power transmission and distribution grids by global power incumbents, AL-59 alloy conductors would have a special significance while designing transmission line networks, as the properties of these conductors enable superior power evacuation while optimising the cost of the entire grid.
