Applications
All-aluminium alloy conductors (AAAC) for high-mechanical-strength overhead transmission lines.
Advantages
- 01 — Maximum strength in the 6xxx series (up to 330 MPa)
- 02 — High fatigue endurance
- 03 — T81 temper — optimal strength/conductivity balance
- 04 — Compliant with IEC and ASTM
