Frequently Asked Questions (FAQ)
Q1
What does AAAC stand for in electrical conductors?
AAAC stands for Aluminum Alloy Conductor. It is designed using a high-strength aluminum-magnesium-silicon alloy to achieve a better strength-to-weight ratio and improved electrical properties compared to traditional AAC conductors.
Q2
What is the standard twisting direction of the outermost layer for AAAC?
As specified in the technical standards, the outermost layer of the Aluminum Alloy Conductor (AAAC) is twisted to the right, which is standardly designated as a (Z) lay direction.
Q3
How does the sectional area affect the electrical resistance of AAAC?
The maximum electrical resistance at 20℃ is inversely proportional to the sectional area. For example, a smaller AAAC conductor like size 16 has a resistance of 1.955 Ω/km, whereas a larger size like 1000 has a significantly lower resistance of 0.033 Ω/km.
Q4
What is the nominal breaking load range of the listed AAAC conductors?
Based on the specification table, the nominal breaking load starts at 4,704 N for the 16 mm² sectional area conductor and reaches up to 280,672 N for the heavy-duty 1005.1 mm² (Code 1000) conductor.
Q5
Are there multiple stranding configurations for the same code name?
Yes. Certain code names offer different configurations. For example, Code Name 50 is available in both a 7-wire stranding (3.00 mm diameter) and a 19-wire stranding (1.75 mm diameter) to suit specific mechanical flexibility and transmission requirements.
