This wire is suitable for use in all practical spans on wood poles, transmission towers, and other structures. Applications range from long, extra high voltage (EHV) transmission lines to sub-service spans at distribution or utilization voltages on private premises.

ACSR (aluminum conductor steel reinforced) 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 core enables higher tensions, less sag, and longer spans than any alternative.

Applicable Standards:

– ASTM B-230 Aluminum wire, 1350-H19 for Electrical Purposes
– ASTM B-231 Aluminum conductors, concentric lay stranded
– ASTM B-232 Aluminum conductors, concentric lay stranded, coated steel reinforced (ACSR)
– ASTM B-341 Aluminum coated steel core wire for aluminum conductors, steel reinforced (ACSR/AZ)
– ASTM B-498 Zinc coated steel core wire for aluminum conductors, steel reinforced (ACSR)
– ASTM B-500 Metallic coat


ACSR (aluminum conductor steel reinforced) has a concentric steel core stranding conductor consisting of Aluminum Alloy 1350-H19 wires, available with Class A, B, or C galvanizing, aluminum coated (AZ), or with aluminum-clad steel core (AL).
