AAC Cable, short for All Aluminum Conductor Cable, is a widely used type of electrical conductor known for its lightweight, high conductivity, and cost-effectiveness. Unlike traditional copper conductors, AAC Cable is composed entirely of aluminum, providing an excellent balance between performance and affordability. Its superior conductivity ensures efficient power transmission, making it ideal for both urban and rural power distribution systems.
Advantages of 477 AAC
The 477 AAC conductor is a specific type of AAC Cable commonly employed in medium to high-voltage transmission lines. Its designation, “477,” refers to the conductor’s cross-sectional area in square millimeters, ensuring it can handle significant electrical loads. 477 AAC is valued for its high tensile strength, excellent corrosion resistance, and long service life. These properties make it particularly suitable for overhead power lines exposed to harsh weather conditions.
Technical Specifications of AAC Cable
The technical performance of AAC Cable sets it apart from other types of conductors. Typically, AAC Cables feature:
High electrical conductivity, typically 61% IACS (International Annealed Copper Standard)
Operating temperature range up to 90°C
Corrosion resistance, especially in outdoor environments
Lightweight structure, reducing the mechanical load on supporting towers and poles
For 477 AAC, these specifications include:
Cross-sectional area: 477 mm²
Diameter: Approximately 24.1 mm
Rated current capacity: Up to 600 A depending on installation conditions
Tensile strength: 120-150 MPa
These characteristics ensure efficient energy transmission while maintaining structural reliability across long distances.
Durability and Reliability
AAC Cable is engineered for durability. Its all-aluminum composition prevents rust and reduces maintenance costs. The 477 AAC conductor is specifically designed to withstand mechanical stress, temperature fluctuations, and ultraviolet exposure. This reliability makes it a preferred choice for power utilities seeking long-lasting performance without frequent replacements.
Application Fields of AAC Cable and 477 AAC
AAC Cable is widely applied in urban and rural electricity distribution networks. Key applications include:
Overhead power transmission lines
Rural electrification projects
Urban utility networks
Substation connections
Specifically, 477 AAC is ideal for high-load transmission lines, industrial power supply, and long-distance overhead lines due to its enhanced mechanical strength and conductivity.
