477 Hawk ACSR Aluminum Conductor Steel Reinforced

Application:
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-232: Concentric Lay Aluminum Conductors
– ASTM B-230: Aluminum 1350-H19 Wire for Electrical Purposes
– ASTM B-498: Zinc Coated (Galvanized) Steel Core Wire for ACSR

Construction:
A solid or concentric stranded central steel core is surrounded by one or more layers of concentric stranded aluminum alloy 1350. The wire is protected from corrosion with a zinc coating.
