The AAC 200mm² All Aluminum Conductor, designed in accordance with IEC 61089, is a bare overhead conductor made of concentric lay-stranded EC-grade (99.7% minimum purity) aluminum wires. Due to its high electrical conductivity, lightweight, and excellent corrosion resistance, this conductor is widely used in low, medium, and high-voltage overhead power lines, particularly in urban and coastal regions.
Application
AAC 200mm² is ideal for:
-
Urban power distribution where short spans and high conductivity are required
-
Coastal areas where corrosion resistance is critical
-
Overhead transmission and distribution lines for low to high voltage applications
-
Service connections using aluminum conductors to ensure compatibility and reduce galvanic corrosion
While aluminum-to-copper transitions are possible, the use of aluminum conductors for both service drops and feeder lines is generally preferred to simplify installation and prevent material incompatibility.

Construction
| Component | Description |
|---|---|
| Conductor Material | Electrolytic grade aluminum (EC grade), minimum 99.7% purity |
| Stranding Type | Concentric lay stranded |
| Structure | One or more layers of hard-drawn 1350-H19 aluminum wires helically wound around a central wire |
AAC conductors are available in various strand configurations depending on the size and mechanical requirements, with the outer layer typically right-hand lay and alternate layers reversed to maintain stability.
