AAC (All Aluminum Conductor) to GOST 839-80 is a bare overhead conductor used for transmitting electricity. This standard outlines the technical specifications for AAC conductors in Russia and some former Soviet Union countries. Unlike insulated cables, these conductors are bare and rely on air for insulation.
Key Specifications & Construction
- Conductor Material: Made from 1350-H19 aluminum alloy wires, which provide good conductivity and a high strength-to-weight ratio.
- Conductor Shape: Available in both circular and sectional configurations.
- Cross-Sectional Area: The range of sizes is from to mm².
- Insulation: None; it is a bare conductor.
- Corrosion Protection: An optional feature is the application of a protective grease or an infusion of the complete cable with grease to prevent corrosion.
Application
AAC conductors are designed for use in overhead power lines in a wide range of climates. They are suitable for environments where the concentration of sulfuric gas is low, specifically not exceeding per day (). This makes them suitable for most macroclimatic regions, excluding areas with very high atmospheric pollution.
