TransPowr® ACSR/AW Bare Overhead Conductor (US)
ACSR/AW is a composite conductor with concentric layers of stranded wires. It is manufactured in accordance with the latest ASTM B549 standard. The central core of the conductor consists of aluminum-clad steel strands, around which one or more layers of aluminum 1350-H19 wires are stranded. The aluminum-clad steel core can be a single strand or a concentric stranded conductor with 7, 19, 37, or more wires. There are many possible combinations of aluminum and steel strands and layers. The sizes and configurations listed in the following pages are the most commonly used for overhead power lines.
Features and Benefits
The ACSR/AW conductor features a core made of a thick layer of aluminum (approximately 10 percent of the nominal wire radius) surrounding steel. This design combines the lightweight and good conductivity of aluminum with the high tensile strength and durability of steel. The accompanying cross-sections illustrate some common strand configurations.
Applications
Aluminum conductors reinforced with aluminum-clad steel wire (ACSR/AW) are ideal for overhead distribution and transmission lines that require high corrosion resistance. They are particularly suitable for areas with high air pollution, such as coastal regions or heavily industrialized locations.
