This product is suitable for transmission and transformation projects that span large distances over rivers, lakes, and other large spans. It is especially designed for ultra-high voltage transmission projects, including large-span transmission projects.

1. Scope of Application:
   This product is suitable for transmission and transformation projects that span large distances over rivers, lakes, and other large spans. It is particularly ideal for ultra-high voltage transmission projects, especially large-span transmission projects.

2. Operating Characteristics:

   1. 20℃ DC Resistance: ≤0.06723Ω/km
   2. Cross-Sectional Area: 727.93mm²
   3. Rated Breaking Force: ≥508.66kN
   4. Stranded Wire Diameter: 35.13mm
   5. Aluminum Alloy Wire 20℃ Resistivity: ≤0.032840Ω·mm²/m
   6. Aluminum Alloy Tensile Strength (After Stranding): ≥299MPa

3. Product Features:

   1. Constructed using concentric stranding with round wires, formed in a single operation.
   2. Exhibits strong load-bearing capacity, reduces sag-related losses during installation, and ensures stable power transmission.
   3. The wire's center is reinforced with G4A extra-strong steel core with mechanical strength ≥1770MPa, which enhances the breaking force, with an aluminum-to-steel cross-sectional ratio of 2.2.
   4. Compared to ordinary steel core aluminum stranded wires, this product offers improved breaking force. The outer layer is made of high-strength aluminum alloy as the main conductive material, which increases tensile strength while ensuring current-carrying capacity.
