AAC(AAAC) Concentric Cables are overhead power distribution lines featuring a central core of aluminum or aluminum alloy strands, surrounded by one or more concentric layers. The AAAC variant uses high-strength aluminum alloy (e.g., 6201 or 6101 grade) to improve tensile strength while maintaining conductivity, making it suitable for longer spans and harsher environmental conditions than standard AAC.
The concentric design ensures uniform mechanical stress distribution, reducing the risk of strand breakage during installation or operation. Standard sizes range from 10 mm² to 300 mm², with typical strand counts of 7, 19, or 37 per layer. The cables are often greased during manufacturing to prevent internal corrosion between strands, a standard practice for overhead conductors in humid climates.
These cables are primarily used in medium to high-voltage distribution networks (up to 69 kV) for utilities, renewable energy farms, and industrial complexes. Their lightweight and high strength-to-weight ratio simplify installation in remote or rugged terrains. Buyers should specify the required current rating (e.g., 300 A for a 50 mm² AAAC cable under standard conditions) and confirm the cable’s sag characteristics for their span length and environmental conditions.
| Conductor Type | AAC or AAAC (Aluminum Alloy 6201/6101 typical) |
| Conductivity | 52.5% IACS (minimum for AAAC, 61% for AAC typical) |
| Tensile Strength | 290 MPa to 320 MPa (AAAC typical), 160 MPa to 200 MPa (AAC typical) |
| Cross-Sectional Area | 10 mm² to 300 mm² (standard range) |
| Strand Count | 7, 19, or 37 per layer (standard concentric configurations) |
| Density | 2.70 g/cm³ (AAC), 2.69 g/cm³ (AAAC typical) |
| Coefficient of Linear Expansion | 23 x 10^-6 /°C (AAC), 23.5 x 10^-6 /°C (AAAC typical) |
| Maximum Operating Temperature | 80°C (AAAC typical), 75°C (AAC typical) |
| Sag Characteristics | Lower sag than AAC at equivalent loads (AAAC advantage) |
| Corrosion Protection | Internal greasing (standard for concentric cables) |
Zhengzhou Zms Cable Co., Ltd. is based in Changzhuang Village, Fumin Road, Zhengzhou, Henan Province, China. The supplier holds an imported tier classification with a harbor trust tier, indicating a verified profile but no recorded response activity. This suggests the need for proactive communication to establish reliability and confirm technical specifications.
The company’s profile lacks details on production scale, certifications, or past projects, so buyers must directly verify compliance with standards like IEC 61089 or ASTM B400 for AAAC cables. The absence of response rate data means inquiries may require persistence, and buyers should request factory audits or third-party inspections for large orders to mitigate risk.

Prior to ordering, confirm the exact aluminum alloy grade (e.g., 6201 for AAAC) and its mechanical properties, as these directly impact the cable’s performance in your application. Request third-party test reports for tensile strength, conductivity, and elongation to ensure compliance with project specifications. For critical infrastructure, consider a factory visit to verify production processes and quality control measures.
Logistics for AAAC cables require coordination due to their weight and length. Zhengzhou’s inland location means shipments may depart from ports like Tianjin or Shanghai, adding transit time. Incoterms such as FOB Zhengzhou or CIF [destination port] are common, with lead times ranging from 6 to 10 weeks for custom orders. Payment terms often include a 30% deposit via TT, with the balance due upon shipment or against a letter of credit.
Quality checks should begin with a visual inspection of the cable’s surface for nicks, corrosion, or irregularities in strand lay. Use a micrometer to measure the diameter of individual strands, ensuring they match the supplier’s specifications. For high-voltage applications, conduct a partial discharge test to detect insulation defects. Always verify that the supplier provides a certificate of compliance with the specified standards and a packing list detailing the quantity, length, and drum numbers.
