All Aluminum Alloy Conductors (AAAC), manufactured in strict compliance with the Chinese National Standard GB/T 1179-1999, are robust and highly efficient bare conductors widely utilized in overhead power transmission and distribution lines. These conductors are crafted from high-strength aluminum-magnesium-silicon alloys, offering a superior blend of mechanical strength, excellent electrical conductivity, and enhanced resistance to environmental factors.
Key Features
- Shape of Conductor: Stranded aluminium (circular) construction, ensuring optimal flexibility for handling and installation, as well as consistent electrical performance.
- Sectional Area Range: Available in a comprehensive range of sizes from 16 mm² to 900 mm², catering to diverse power transmission and distribution requirements, from smaller lines to larger capacity routes.
- Insulation: N/A (Bare Conductor) – designed for overhead applications where ambient air serves as the primary insulation medium.
- High Strength-to-Weight Ratio: The aluminum alloy composition provides excellent mechanical strength with a relatively low weight. This allows for longer spans between support structures, leading to reduced infrastructure costs for towers and poles.
- Superior Corrosion Resistance: Inherently resistant to corrosion, making AAAC conductors particularly well-suited for deployment in challenging environments such as coastal regions or areas with high industrial pollution, thereby reducing maintenance needs and extending service life.
- Good Electrical Conductivity: Offers efficient power transmission with minimal energy losses, contributing to the overall efficiency of the electrical grid.
- Improved Sag Characteristics: Exhibits favorable sag performance under various loading conditions (e.g., wind, ice), which is crucial for stable and reliable overhead line design.
- Durability and Longevity: The robust alloy construction ensures a long operational life with high reliability, even under demanding environmental conditions.
Application
AAAC conductors conforming to GB/T 1179-1999 are extensively employed as bare overhead conductors in various electrical infrastructure projects:
- Overhead Power Transmission Lines: Used for high and medium voltage transmission, particularly where the combination of light weight and high strength offers significant advantages in construction and long-term performance.
- Overhead Power Distribution Networks: Ideal for both primary and secondary distribution lines, serving urban, suburban, and rural areas.
- Coastal and Industrial Regions: Highly recommended for deployment in environments with high salinity or atmospheric pollution due to their exceptional corrosion resistance.
- Long-Span Installations: Their superior mechanical properties enable longer distances between support structures, leading to cost efficiencies in material and labor.
Standard
Our AAAC - All Aluminum Alloy Conductors are meticulously manufactured and tested to comply with:
- GB/T 1179-1999: This is the Chinese National Standard for 'Round Wire Concentric Lay Stranded Overhead Electrical Stranded Conductors.' It specifies the material, construction, and testing requirements for all aluminum alloy conductors, ensuring adherence to national quality and performance benchmarks.
Construction
AAAC conductors are constructed from concentric lay stranded wires made from high-strength aluminum-magnesium-silicon alloy. The specific number of wires and their precise stranding configuration are engineered to meet the stringent mechanical and electrical performance criteria outlined in the GB/T 1179-1999 standard. The stranded circular shape optimizes both ease of handling during installation and aerodynamic stability in service.
