ACSR conductors are manufactured in accordance with the requirements of the latest issue of ASTM B232. The steel strand or strands form the central core of the conductor, around which is stranded one or more layers of aluminum 1350-H19 wires. The steel core may consist of a single strand or a concentric-stranded cable of 7, 19, 37 or more wires. Numerous combinations of aluminum and steel strands and layers are possible. The sizes and strandings listed on the following pages are those most frequently used for overhead lines. Features and Benefits: ACSR conductors are recognized for their record of economy, dependability and favorable strength/ weight ratio. ACSR conductors combine the light weight and good conductivity of aluminum with the high tensile strength and ruggedness of steel. In line design, this can provide higher tensions, less sag and longer span lengths than obtainable with most other types of overhead conductors. The steel strands are added as mechanical reinforcement. The cross-sections above illustrate some common strandings. Features and Benefits (cont d.): The steel core wires are protected from corrosion by galvanizing. The standard Class A zinc coating is usually adequate for ordinary environments. For greater protection, Class C galvanized coatings may be specified. High-Strength (/GA3), Extra-High-Strength (/GA4) and Ultra-High- Strength (/GA5) steel core with Class A galvanizing and High-Strength (/MA3), Extra-High-Strength (/MA4) and Ultra-High-Strength (/MA5) steel core with Class A zinc-5% aluminum mischmetal coating are also available. The product is also available with corrosion inhibitor treatment applied to the central steel component. Applications: Aluminum Conductors, Steel-Reinforced (ACSR) are extensively used for overhead distribution and transmission lines. Options: High-conductivity aluminum (/HC) (62.2% IACS) Regular-strength Class C galvanized steel core (/GC2) High-strength Class A galvanized steel core (/GA3 to ASTM B606) Options (cont d.): Extra-high-strength Class A galvanized steel core (/GA4 to ASTM B957) Ultra-high-strength Class A galvanized steel core (/GA5 to ASTM B957) Regular-strength Class A zinc-5% aluminum mischmetal alloy-coated steel core (/MA2 to ASTM B802) High-strength Class A zinc-5% aluminum mischmetal alloy-coated steel core (/MA3 to ASTM B803) Extra-high-strength Class A zinc-5% aluminum mischmetal alloy-coated steel core (/MA4 to ASTM B958) Ultra-high-strength Class A zinc-5% aluminum mischmetal alloy-coated steel core (/MA5 to ASTM B958) Aluminum-clad steel core (/AW) see ACSR/AW catalog section Non-specular surface finish (/NS) Compact ACSR (ASTM B401) designs are available Trapezoidal-shaped aluminum strands (/TW) see ACSR/TW catalog section Aluminum Alloy Steel Reinforced Conductors AACSR (ASTM B711) designs are available For more information, or information on other conductor sizes, designs and/or specific installation requirements not shown in the tables, contact your General Cable sales representative or . 12/12 90
