Frequently Asked Questions (FAQ)
What is an Aluminum Stranded Conductor (AAC)?
AAC (All Aluminum Conductor) is a refined aluminum stranded conductor designed primarily for overhead electricity transmission and distribution lines. It offers excellent corrosion resistance and high electrical conductivity.
What do the Code Names (e.g., MIDGE, WASP, SPIDER) signify?
These standardized code names are used in the power industry to quickly identify specific physical dimensions, stranding configurations, and electrical ratings of the conductor without listing the entire specification table.
What does the "Z" twist direction mean for AAC?
The "Z" twist indicates that the outermost layer of the aluminum strands is layed or wound in a right-hand direction, which is standard for ensuring structural integrity and mechanical compatibility during installation.
Why is the resistance measured specifically at 20℃?
Electrical resistance changes with temperature. 20℃ is the standard reference temperature used worldwide to accurately compare and calculate the maximum DC resistance of electrical conductors.
In what environments is AAC most commonly used?
AAC is highly preferred in coastal and urban areas where corrosion resistance is crucial, and where spans are relatively short to medium, as it does not contain a steel reinforcement core like ACSR.
