Bare ACSR AW

ACSR/AW conductors consist of an aluminum-clad steel core surrounded by one or more layers of aluminum strands. The aluminum cladding on the steel core provides improved corrosion resistance compared to standard galvanized steel cores. The outer aluminum strands ensure good electrical conductivity, while the aluminum cladding slightly enhances overall conductivity compared to traditional ACSR conductors with galvanized steel cores. The steel core retains its high tensile strength, making the conductor suitable for long spans and high-stress applications. Additionally, the aluminum cladding offers superior resistance to corrosion, making ACSR/AW conductors ideal for harsh environments such as coastal or industrial areas. These conductors are available in various stranding configurations to meet specific mechanical and electrical requirements.

● Overhead Power Transmission: Extensively used in high-voltage power transmission lines, especially in areas prone to corrosion.

● Distribution Lines: Suitable for medium and low-voltage distribution networks, providing reliable performance over long spans.

● Coastal and Industrial Areas: Preferred in environments where standard galvanized steel core conductors might suffer from accelerated corrosion.

● River Crossings and Long Spans: Ideal for crossing rivers and other wide spans due to their high strength and enhanced corrosion resistance.
