Stranded Overhead Shield Wire (Ground Wire)
Concentric-lay-stranded conductors made of Aluminum-clad Steel wires.
Commonly used for overhead shield wire in high corrosion areas such as industrial, seashore, and desert environments. Overhead shield wire provides lightning protection and distributed grounding important for safe operation of power lines. OPGW, of which has aluminum-clad steel as a component, is also used for overhead shield wire.
ASTM B416 – Bare concentric-lay-stranded conductors made from bare, hard-drawn, round, Aluminum-clad Steel wires for general use of electrical purposes.
