Frequently Asked Questions (FAQ)
What does AAAC stand for and what is its primary application?
AAAC stands for Aluminum Alloy Conductor. It is primarily used as bare overhead conductor cables for power distribution and transmission lines where high mechanical strength and good electrical conductivity are required.
What does the Z-twist note signify for AAAC conductors?
The note indicates that the outermost layer of the Aluminum Alloy Conductor is stranded/twisted to the right (Z-direction). This standard lay direction ensures structural integrity and consistent mechanical performance during installation and operation.
Why do some code names like 50, 150, and 240 have multiple listings?
These code names have different wire configurations (different strand diameters and number of strands). For example, code name 50 is available in both a 7-strand (3.00 mm) configuration and a 19-strand (1.75 mm) configuration to offer different mechanical flexibility and load properties.
How does the sectional area of AAAC relate to its electrical resistance?
As the sectional area of the conductor increases, the maximum electrical resistance at 20℃ decreases. For instance, a 16 mm² conductor has a resistance of 1.955 Ω/km, whereas a larger 1000 mm² conductor has a resistance of just 0.033 Ω/km.
What is the range of nominal breaking loads for the AAAC sizes listed?
The nominal breaking load ranges from 4,704 N for the smallest size (Code 16) up to 280,672 N for the largest size (Code 1000), depending on the conductor's sectional area and stranding configuration.
