Aluminum-Alloy Conductors Steel Reinforced Aacsr for Overhead

1. Standards
(1)ASTM B711 – 13 Standard Specification for Concentric-Lay-Stranded Aluminum-Alloy Conductors, Steel Reinforced (AACSR) (6201)
(2)IEC 61089 Round wire concentric lay overhead electrical stranded conductors
(3)DIN 48206 Aluminum Alloy Conductor Steel Reinforced

2. Construction
AACSR is a concentrically stranded conductor composed of one or more layers of 6201 -T81 aluminum alloy wire stranded with a high-strength coated steel core. The core may be single wire or stranded depending on the size.
The proportions of aluminum alloy and steel can be varied to obtain the relation between currentcarrying capacity and mechanical strength best suited to each application.

3. Applications
Used as bare overhead transmission cable and as primary and secondary distribution cable. AACSR offers optimal strength for line design. Variable steel core stranding enables desired strength to be achieved without sacrificing ampacity.

4. Features
AACSR is suitable for overhead line for long span at medium voltage, high voltage and extra-high voltage, such as used in the area of mountain, hill, or the place where snow is heavy. The AACSR has a much higher strength and its usage is ideal on long spans or under very severe mechanical conditions.
(1)offers optimal strength for line design.
(2)improved strength to weight ratio
(3)ideal for extra long span with heavy load
(4)excellent resistance to corrosion.
(5)Compared with ACSR, the tensile strength of aluminum conductor is more strong.
