Bare ACSR conductors are intended for use as overhead transmission, primary or secondary distribution conductor. The steel wire core and the outer aluminum wires provide an optimal balance between conductor strength and current carrying capacity, allowing for greater conductor currents at longer spans between supports. This conductor is often used as the messenger for multi conductor neutral supported conductor designs Construction
Aluminum alloy 1350-H19 wires concentrically stranded over a steel wire core. The steel wire core is Class A Zinc coated (Code GA2). Specifications
These conductors are manufactured and tested to meet or exceed the following standards:
• ASTM B230 – Aluminum 1350–H19 Wire for Electrical Purposes
• ASTM B231 – Concentric-Lay-Stranded Aluminum 1350 Conductors
• ASTM B232 – Concentric-Lay-Stranded Aluminum Conductors, Coated-Steel Reinforced (ACSR)
• ASTM B498 – Zinc-Coated (Galvanized) Steel Core Wire for Use in Overhead Electrical Conductors
• CSA C60888 – Zinc-coated steel wires for stranded conductors
• CSA C60889 – Hard-drawn aluminum wire for overhead line conductors
• CSA C61089 – Round wire concentric lay overhead electrical stranded conductors

NOTES
1) Dimensions and weights are subject to standard manufacturing tolerances and are subject to change without notice.
2) Resistance is calculated using metal conductivity of 61.2% IACS for EC (1350) at 20ºC and 8% IACS for steel at 20ºC.
3) Ampacities are based on 75ºC conductor temperature, 25ºC ambient, 2 ft/s wind, full sun, an emissivity of 0.5 and a coefficient of solar absorption of 0.5, at sea level.
