What is AACSR Conductor according to IEC 61089?
AACSR (Aluminum Alloy Conductor Steel Reinforced) is a high-strength stranded conductor consisting of aluminum-magnesium-silicon alloy wires stranded around a central core of steel wires, manufactured in compliance with international IEC 61089 standards.
What are the advantages of using A2/S1A type AACSR?
The A2/S1A designation indicates a specific alloy and steel strength combination that offers an excellent balance between electrical conductivity and mechanical tensile strength, making it ideal for overhead power lines with long spans.
How does the steel core affect the performance of AACSR?
The steel core significantly increases the rated strength of the conductor, allowing it to support higher mechanical loads and reducing sag over long distances compared to all-aluminum conductors.
What is the maximum DC resistance specified for these conductors?
The Max D.C. Resistance at 20℃ varies depending on the nominal area, ranging from approximately 1.7934 Ohms/km for smaller 26mm² sizes down to 0.0258 Ohms/km for larger 1120mm² industrial sizes.
In what environments is AACSR most commonly used?
AACSR is commonly used in overhead transmission and distribution lines, particularly in areas requiring high mechanical strength, river crossings, or regions with severe weather conditions like high winds or ice loading.
Are these conductors compatible with standard hardware?
Yes, being manufactured to IEC 61089 standards ensures that these conductors are compatible with standard international fittings, clamps, and tensioning hardware designed for AACSR specifications.
