Frequently Asked Questions (FAQ)
What is the standard twisting direction for AAAC conductors?
According to the technical specifications of the Aluminum Alloy Conductor (AAAC), the outermost layer of the wires is twisted to the right, which is standardly designated as a Z-twist direction.
At what temperature is the maximum resistance of AAAC measured?
The maximum electrical resistance values listed in the specification table for the Aluminum Alloy Conductor (AAAC) are measured at a standard reference temperature of 20℃.
How does the sectional area of AAAC relate to its maximum resistance?
There is an inverse relationship between the sectional area and electrical resistance. As the sectional area increases (from 18.4 mm² to 1440.9 mm²), the maximum resistance at 20℃ decreases significantly (from 1.7896 Ω/km down to 0.0231 Ω/km).
What determines the nominal breaking load of an Aluminum Alloy Conductor?
The nominal breaking load (measured in kN) is determined by the sectional area, the wire diameter, and the number of strands. Larger conductors (such as code 1250 with 91 strands) offer a much higher breaking load (up to 424.41 kN) compared to smaller sizes.
What are the typical stranding configurations for AAAC?
Depending on the required sectional area and mechanical strength, AAAC conductors are manufactured in various stranding structures including 7, 19, 37, 61, or 91 individual wire strands.
