Product Description
AACSR Conductor : Product Description and Specifications
The AACSR (Aluminum Alloy Conductor Steel Reinforced) is engineered for environments that demand more than what standard ACSR can provide. By stranding Al-Mg-Si (Aluminum-Magnesium-Silicon) alloy wires around a high-strength galvanized or aluminum-clad steel core, we’ve created a conductor with a massive strength-to-weight ratio. This specific alloy combination doesn’t just conduct; it adds a layer of mechanical toughness that allows the cable to withstand high-tension spans and severe weather without compromising electrical efficiency. Whether your project involves river crossings or heavy-snow regions, the AACSR provides the extra “backbone” needed for long-term grid stability.

Advantages
AACSR Conductor : Benefits and Features
Tension Mastery: Al-Mg-Si alloy paired with high-tensile steel supports river crossings and long-span tower grids.
Sag Stability: High-strength alloy layers minimize mechanical sag under heavy ice and high wind loads.
Core Customization: Available with Class A/B/C galvanization or Aluminum-Clad (AW) steel to match regional corrosion specs.
Tower Savings: High strength-to-weight ratio reduces tower loads and expands span distances.
Harsh Environment Guard: Optional grease filling blocks oxidation in volatile coastal or industrial zones.
Grid Efficiency: Precision-stranded alloy ensures low line losses for long-distance transmission.

Production Processes Of Overhead Bare Conductors
JOCA operates a digitalized production line specifically for manufacturing overhead bare conductors. The process flow starts with raw aluminum rod inspection, moving through high-speed wire drawing and precision stranding within a single, data-tracked environment. To prevent defects, we’ve integrated intelligent sensors that monitor the diameter and surface smoothness of every conductor layer in real-time. This automated setup utilizes laser measurement technology to enforce strict adherence to ASTM, IEC, and BS standards. By removing manual variability, the system ensures that every reel of AAC, AAAC, or ACSR maintains consistent tensile strength and stable electrical performance, even under extreme environmental exposure.
Packing For Shipment
To meet various transportation needs, there are many methods of packaging that can be used.
Have more questions?
Q: What is the core technical difference between AACSR and ACSR?
A: Material composition is the key. While ACSR uses pure 1350 aluminum, AACSR utilizes Al-Mg-Si alloy. This substitution significantly enhances the conductor’s tensile strength and sag performance, making it a “heavy-duty” alternative to standard ACSR.
Q: When is AACSR preferred over AAAC or standard ACSR?
A: AACSR is the ideal middle ground for extreme spans. It offers more mechanical “muscle” than all-alloy AAAC and better structural stability than ACSR, specifically in regions where long distances between towers are mandatory.
Q: What role does the steel core play in this alloy conductor?
A: The galvanized or aluminum-clad steel acts as the primary tension member. It handles the raw mechanical load, allowing the Al-Mg-Si alloy layers to focus on electrical delivery without stretching or snapping under high tension.
Q: Is grease filling necessary for AACSR?
A: It depends on the installation site. While not mandatory, we recommend grease for coastal or high-pollution industrial zones. It provides a critical oxidation barrier for the steel core, extending the grid’s overall service life.
Q: How does AACSR perform under high thermal loads?
A: It excels in high-temperature scenarios. The Al-Mg-Si alloy offers superior creep resistance compared to pure aluminum, meaning the conductor maintains its ground clearance even during peak summer power demands.
Q: Can I specify an Aluminum-Clad Steel (AW) core for AACSR?
A: Absolutely. We provide AW steel cores for projects requiring maximum corrosion protection. The aluminum-to-aluminum interface between the core and the strands eliminates bi-metallic corrosion risks.
Q: What are the standard packaging options for large projects?
A: We offer a range of reinforced wooden reels and steel drums. Packaging is determined by the conductor’s total weight and the terrain of the job site to ensure safe handling during stringing operations.
Q: How do I request a technical datasheet or bulk quotation?
A: Please submit your project specifications through our “Inquiry” portal or contact our engineering department directly. We provide full sag-tension charts and customized pricing based on your required span distances.
