Frequently Asked Questions (FAQ)
Q:
What material configuration does the "AL 3/ST1A" designation represent?
"AL 3" indicates the outer conductor layers are made of high-strength Aluminum Alloy, while "ST1A" refers to the core reinforced with galvanized steel wire (Class A coating) for superior tensile strength.
Q:
How is the total sectional area of the conductor determined?
The total sectional area is the sum of the nominal cross-sectional areas of the aluminum alloy wires and the steel core wires (Total Area = Aluminum Alloy Area + Steel Area).
Q:
At what temperature is the Maximum D.C. Resistance rated?
All Maximum D.C. Resistance values listed in the technical specification table are calculated and rated at a standard reference temperature of 20°C.
Q:
What role does the steel core play in these conductors?
The galvanized steel core (ST1A) provides the primary mechanical load-bearing capacity, significantly increasing the rated tensile strength (kN) to support long spans and harsh environmental conditions.
Q:
Can the stranding structure and wire diameters be customized?
Yes. While standard configurations are shown in the table (e.g., 6, 12, 24, 26, 48, or 54 aluminum wires), custom wire diameters and stranding ratios can be manufactured to meet specific electrical and mechanical design requirements.
