Frequently Asked Questions (FAQ)
What is the standard twisting direction for AAC outermost layers?
As detailed in the specifications, the outermost layer of the Aluminum Stranded Conductor (AAC) is twisted to the right, which represents a Z-direction lay (Z-twist).
How does the sectional area affect the electrical resistance of AAC?
There is an inverse relationship between the sectional area and the electrical resistance. As the nominal sectional area increases (from 10 mm² to 1500 mm²), the maximum resistance at 20℃ decreases significantly (from 2.8633 Ω/km down to 0.0193 Ω/km).
What range of nominal breaking loads does this AAC specification cover?
The nominal breaking load for the listed Aluminum Stranded Conductors ranges from 1.95 kN for the smallest size (10 mm² sectional area) up to 240 kN for the largest size (1499.2 mm² sectional area).
What stranding options are available for these conductors?
The conductors are engineered with different wire numbers to ensure optimal flexibility and strength. Standard configurations include 7-wire, 19-wire, 37-wire, 61-wire, and 91-wire stranded structures depending on the code name.
How is the linear mass of the conductor calculated and represented?
Linear mass indicates the weight of the conductor per unit length and is measured in kilograms per kilometer (kg/km). In this specifications table, the linear mass ranges from 27.4 kg/km for code 10 up to 4160.2 kg/km for code 1500.
