What's 556.5 ACSR Osprey Conductor
The ACSR Osprey Conductor (556.5 AWG or kcmil) is a widely used aluminum conductor steel reinforced (ACSR) cable designed for overhead power transmission and distribution systems. It is manufactured with 18 aluminum strands (0.1758 inch diameter) wrapped around a core of 1 galvanized steel strands (0.1758 inch diameter). This unique construction delivers an ideal balance of lightweight aluminum conductivity and high mechanical strength from the steel core,enables higher tensions, less sag, and longer spans than any alternative.

Standards:
Our 556.5 ACSR Osprey Conductor is manufactured and rigorously tested in strict accordance with the following industry standards, guaranteeing high quality and performance:
Construction:
The ACSR Osprey Conductor features a precise construction designed for optimal performance:
1.Aluminum 1350-H19 wires, concentrically stranded about a steel core. Standard core wire for ACSR is class A galvanized
2.Class A core stranding is also available in zinc-5% aluminum-mischmetal alloy coating.
3.For aluminum-clad (AW) ACSR, please refer to the ACSR/AW catalog sheet
