FAQ
1. What is AACSR cable used for?
AACSR (Aluminum Conductor Steel-Reinforced) is primarily used for high-voltage overhead power transmission (up to 500 kV) due to its strength-to-weight ratio, ideal for long spans across rivers, mountains, or rural areas.
2. Why choose AACSR over ACSR?
AACSR replaces some aluminum strands with aluminum alloy layers, offering higher conductivity (3% better than ACSR) while maintaining tensile strength, reducing energy loss over distances.
3. What's the steel core's role?
The galvanized steel core provides mechanical strength to withstand wind loads, ice, and thermal expansion, minimizing sag in extreme temperatures.
4. What are the temperature limits?
Continuous operating temperature: 90°C (194°F). Emergency overload: 180°C (356°F) for short durations.
5. How to calculate AACSR ampacity?
Use IEEE 738 standards, factoring in ambient temperature, conductor diameter (e.g., 26.8 mm for Drake type), and wind speed.
6. Is AACSR corrosion-resistant?
Yes, but galvanized steel cores in coastal areas may require zinc-aluminum alloy coatings for enhanced longevity.
7. Typical spans for AACSR installation?
Flat terrain: 300-500 meters. Mountains/valleys: 50-200 meters (due to tension variations).
8. Standards compliance?
Meets IEC 61089, ASTM B232, and EN 50182, with optional ISO 9001 certification for quality-controlled manufacturing.
9. Cost comparison with copper cables?
AACSR is 60-70% cheaper than copper, with similar conductivity, making it the preferred choice for utility-scale projects.
10. How to store AACSR reels?
Indoors: Avoid moisture; keep reels on pallets. Outdoors: Cover with UV-resistant tarps, rotate every 3 months to prevent deformation.
