ASTM B230, B502, B549.
Aluminum Alloy 6201 wires and the steel cores are concentrically stranded and wrapped helically around a central wire. The additional corrosion protection is available through the application of grease to the cores or infusion of the complete cable with grease.
The ACSR/AW conductors are also suitable for use in all practical transmission towers,and other structures. Application range from extra high voltage(EHV) transmission lines to sub-service spans at distribution or utilization voltages on private premises as like as ACSR.
ACSR/AW(Aluminum Conductor Aluminum-Clad-Steel Reinforced) has also a long service record because of its economy ,dependability, and strength to weight ratio. The combined light weight and high conductivity of aluminum with strength of the steel cores enable higher tensions ,lesssag,and longer spans than any alternative as like as ACSR.Compared with ACSR ,the cores are aluminum-clad-steel. And its property of corrosion resisting is improved a lot obviously.
