Frequently Asked Questions
Q1: What is the range of Nominal Area covered in this specification?
The nominal area of the conductors ranges from a minimum of 26 mm² to a maximum of 1120 mm², offering options for various transmission line capacities.
Q2: How does the conductor diameter scale with the nominal area?
The overall diameter of the conductor scales proportionally with the nominal area, starting from 5.93 mm for the 26 mm² nominal area up to 48.6 mm for the 1120 mm² nominal area.
Q3: What is the relationship between conductor size and Maximum D.C. Resistance at 20℃?
As the nominal area increases, the Maximum D.C. Resistance decreases significantly. For instance, the 26 mm² conductor has a resistance of 1.7934 Ω/km, whereas the 1120 mm² conductor has a resistance of only 0.0258 Ω/km.
Q4: What are the stranding configurations for the steel core?
Depending on the conductor size and strength requirements, the steel core stranding consists of either 1 wire (for smaller sizes like 26 mm² to 200 mm²), 7 wires (for medium to large sizes), or 19 wires (for heavy-duty configurations like 560 mm² to 1120 mm²).
Q5: What is the rated strength of the 1120 mm² nominal area conductor?
The largest conductor listed in the specifications (1120 mm² nominal area, with a total sectional area of 1394 mm²) features a rated strength of 499.93 kN.
Q6: Why are there two listings for certain nominal areas like 125 mm², 160 mm², and 200 mm²?
These sizes offer different steel core configurations (e.g., 1 steel wire vs. 7 steel wires). This allows engineers to select either a lighter conductor or a stronger conductor with higher rated strength depending on the span and tension requirements of the transmission line.
