Frequently Asked Questions (FAQ)
What is an Aluminum Stranded Conductor (AAC)?
AAC (All Aluminum Conductor) is a stranded conductor made from refined aluminum with a minimum purity of 99.7%. It is widely used in overhead electricity distribution lines, particularly in urban areas with short spans and high conductivity requirements.
What standards do the AAC code names in the table refer to?
The code names listed in the table (such as MIDGE, GNAT, WASP, and BEE) correspond to standard industry designations (typically conforming to British Standard BS 215 Part 1) used to simplify ordering and technical specifications.
What does the Z-twist (right-hand lay) specification mean?
The note indicates that the outermost layer of the stranded aluminum wire is twisted in the right-hand (Z) direction. This standard lay direction ensures uniform mechanical stability and compatibility with standard line fittings and tension clamps.
How does the operating temperature affect the maximum resistance of AAC?
The electrical resistance values in the table are specified at a standard baseline temperature of 20°C. As the operating temperature of the conductor increases during power transmission, the resistance will increase accordingly, which must be factored into voltage drop calculations.
Why choose AAC over ACSR (Aluminum Conductor Steel Reinforced)?
AAC offers excellent corrosion resistance and higher conductivity per weight compared to ACSR. It is the preferred choice for coastal areas and urban installations where spans are relatively short and high mechanical tensile strength from a steel core is not required.
