Frequently Asked Questions (FAQ)
1. What does the Code Name (e.g., "15-AL 3/3-ST1A") represent?
The code name indicates the specific structure of the conductor. "AL" refers to the Aluminum alloy section, "ST" represents the Steel core section, and the numbers indicate their respective nominal cross-sectional areas and material grades (e.g., ST1A grade steel core).
2. How do I transition from Old Code Names to New Code Names?
You can easily cross-reference the specifications using our table. For instance, the old code name "16/2.5" directly corresponds to the new standard designation "15-AL 3/3-ST1A", sharing similar physical and electrical properties.
3. Why is Max. D.C. Resistance at 20℃ critical?
Max. D.C. Resistance at 20℃ (measured in Ohms/km) determines the electrical efficiency of the conductor. Lower resistance values mean less power loss during transmission, which is crucial for high-efficiency grid layouts.
4. What is the relation between Rated Strength and the steel core?
The steel core (ST1A) provides the primary mechanical tensile strength (Rated Strength in kN). As the sectional area of the steel core increases relative to the aluminum alloy, the overall rated strength of the conductor increases significantly to support long-span installations.
5. Are these conductors suitable for high-voltage transmission lines?
Yes, these Aluminum Alloy Conductor Steel Reinforced (AACSR/ACSR) specifications are specifically designed for overhead electrical transmission and distribution lines, offering an optimized balance between conductivity, weight, and mechanical strength.
