ACSR/AW bare conductors are specifically designed for overhead transmission and distribution lines in severe environments with high corrosion concerns. These conductors serve effectively in coastal areas, industrial zones with chemical emissions, and regions with high atmospheric pollution. ACSR/AW provides enhanced corrosion protection while maintaining the mechanical advantages of steel-reinforced conductors, making it ideal for applications requiring both strength and extended service life under harsh conditions.
ACSR/AW conductors incorporate a central core of aluminum-clad steel wires surrounded by one or more layers of 1350-H19 hard-drawn aluminum wires in concentric layers. The steel core provides mechanical strength while the aluminum cladding on the steel creates a protective barrier against corrosion and galvanic action. This construction maintains a standard operating temperature of 75°C continuously, with emergency ratings up to 100°C, while offering significantly improved corrosion resistance compared to standard ACSR conductors.
