ACSR Hawk Conductor
Hawk belongs to the ASTM bird-name series: a 26/7 construction with a total cross-section of about 281 mm², in the transmission-line class. It is offered in two builds: standard ACSR (ASTM B232) and the aluminium-clad-steel-core ACSR/AW (ASTM B549) for corrosive environments.

The 26/7 construction is the ASTM series' familiar balance of capacity and strength, making Hawk a common mid-range transmission choice. Both tables below quote the factory catalogue — the AW build trades slightly different core properties for better core conductivity and life in coastal and industrial atmospheres.
