Frequently Asked Questions (FAQ)
Q: What is Aluminum Stranded Conductor (AAC) used for?
AAC (Aluminum Stranded Conductor) is primarily used for overhead electricity transmission and distribution lines. It is ideal for urban areas with short spans where high conductivity and flexibility are required.
Q: What do the code names like "MIDGE" or "WASP" represent?
These code names are standardized industry terms (often originating from British Standards) used to easily identify specific conductor sizes, stranding configurations, and physical properties without confusing long numerical specifications.
Q: What is the significance of the "Z" twist direction in AAC?
The "Z" twist indicates that the outermost layer of the stranded aluminum wires is wound in a right-hand direction. This standard lay direction ensures mechanical stability during installation and compatibility with standard line fittings.
Q: Why is the maximum electrical resistance measured at 20℃?
20℃ (68°F) is the globally accepted standard reference temperature for electrical conductivity measurements. Since resistance increases as the temperature of aluminum rises, this standard allows for accurate comparisons between different conductor sizes.
Q: How does stranding affect the flexibility of the conductor?
Conductors with a higher number of strands (e.g., 19 or 37 strands) offer greater flexibility and ease of handling compared to those with fewer strands (like 7 strands) for a similar sectional area, making them easier to install around bends.
