ACSR (Aluminum Conductor Steel Reinforced) is a type of overhead power transmission conductor widely used in electrical grids. It combines the advantages of aluminum and steel, offering high strength, excellent conductivity, and corrosion resistance.
Outer Aluminum Layers: Multiple aluminum strands are twisted around the exterior, responsible for conducting electricity. Aluminum provides excellent conductivity and is lightweight.
Central Steel Core: One or more high-strength steel strands form the core, providing mechanical strength to support the conductor and withstand tension.
High Strength: The steel core enhances the tensile strength, making it suitable for long spans and heavy-load applications.
Good Conductivity: The outer aluminum strands ensure high electrical conductivity.
Corrosion Resistance: Both aluminum and steel offer corrosion resistance, extending the conductor's lifespan.
Cost-Effectiveness: Compared to pure copper conductors, ACSR is more economical while maintaining performance.
