Frequently Asked Questions (FAQ)
Q What is the difference between the standard Code Name and the Old Code Name for ACSR conductors?
The modern standard Code Name (e.g., 53-AL1/9-ST1A) provides technical details regarding the cross-sectional area and material composition, while the Old Code Name (e.g., RABBIT) is a traditional animal-based designation historically used in the industry for quick identification.
Q How does the steel core affect the Nominal Breaking Load of the ACSR conductor?
The galvanized steel core significantly increases the mechanical strength of the conductor. For example, conductors with a higher ratio of galvanized steel or larger steel wire diameters, such as the "SKUNK" (7 steel wires, 2.59 mm diameter), exhibit a much higher Nominal Breaking Load (52.79 kN) compared to conductors with a single steel wire core.
Q Why does the electrical resistance decrease as the sectional area of aluminum increases?
Electrical resistance is inversely proportional to the cross-sectional area of the conductor. As the sectional area of the highly conductive aluminum increases (e.g., from 10.6 mm² in "MOLE" to 528.5 mm² in "MOOSE"), the Maximum Resistance at 20℃ drops significantly from 2.7027 Ω/km to 0.0547 Ω/km, enabling higher current carrying capacity with lower power loss.
Q What does the "Z" twist direction refer to in ACSR specifications?
The "Z" twist direction specifies that the outermost layer of aluminum wires is stranded or twisted to the right. This is a standard manufacturing specification to ensure uniformity, consistent mechanical behavior, and compatibility with installation hardware.
Q How is the total sectional area of an ACSR conductor calculated?
The total sectional area is the sum of the sectional areas of the inner galvanized steel core and the outer aluminum layers. In the specification table, this is represented by adding the "Aluminium mm²" and the "Galvanized steel mm²" columns to get the "Total" sectional area.
