IEC Standard ACSR Conductor IEC61089 Aluminum Rope Overhead Cable
Introductions:
ACSR conductor(Aluminum Conductor Steel Reinforced) are suitable for use in all practical spans on wood poles, 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.
ACSR conductor has 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 ,less sag,and longer spans than any alternative.
