Frequently Asked Questions (FAQ)
What is the standard lay direction for these AAC conductors?
According to the technical specifications, the outermost layer of these Aluminum Stranded Conductors (AAC) is twisted to the right, which is designated as a Z-lay configuration.
How does the number of wires change with the sectional area?
The wire stranding configuration transitions from 7 wires for smaller sizes (up to 63.2 mm²), to 19 wires (100.1 to 249.6 mm²), 37 wires (314.5 to 560 mm²), 61 wires (631.3 to 1000.6 mm²), and up to 91 wires for the largest conductors (1120.8 to 1499.2 mm²).
What is the maximum electrical resistance at 20℃ for the smallest AAC size?
The AAC conductor with a nominal code name of 10 (10.0 mm² sectional area) features a maximum DC resistance of 2.8633 Ω/km at 20℃.
What is the nominal breaking load range of these conductors?
The nominal breaking load ranges from 1.95 kN for the smallest size (Code Name 10) up to 240 kN for the largest size (Code Name 1500), reflecting the tensile strength scaling with sectional area.
How does the linear mass of AAC scale with the conductor size?
The linear mass starts at 27.4 kg/km for the 10 mm² conductor and increases up to 4160.2 kg/km for the 1499.2 mm² conductor, aligning directly with the volume of aluminum used per kilometer.
