Frequently Asked Questions (FAQ)
Q
What does the designation "AL 3/ST1A" signify in the table?
"AL 3" designates the aluminum alloy component of the conductor, while "ST1A" specifies the strength class of the galvanized steel core wire. Together, they outline the structural composition of the stranded conductor.
Q
How is the total sectional area of the conductor determined?
The total sectional area is the combined sum of the sectional areas of the aluminum alloy and the steel core. For example, in the "15-AL 3/3-ST1A" conductor, the 15.3 mm² aluminum alloy area plus the 2.5 mm² steel area equals a total of 17.8 mm².
Q
Why is D.C. resistance measured specifically at 20℃?
Measuring D.C. resistance at 20℃ is an industry standard that allows for consistent comparison between different conductor specifications. Resistance values vary with temperature, so a fixed baseline is essential for accurate electrical calculations.
Q
What is the relationship between rated strength and steel content?
The steel core (ST1A) provides the primary mechanical tensile strength. Generally, conductors with a higher proportion of steel sectional area or more steel strands exhibit significantly higher Rated Strength (measured in kN), making them suitable for long-span installations.
Q
How does the linear mass affect transmission line design?
Linear mass (measured in kg/km) indicates the weight of the conductor per unit length. Higher linear mass requires more robust support structures, towers, and tensioning systems to safely handle the physical load and control conductor sag.
