AAAC (AL59) Conductor – High-Strength Aluminium Alloy Conductor

Product Overview

AAAC (All Aluminium Alloy Conductor), designated as AL59, is a high-performance bare overhead conductor manufactured from aluminium-magnesium-silicon (Al-Mg-Si) alloy wires.

Designed to combine good electrical conductivity with enhanced mechanical strength, AL59 provides an effective balance between current-carrying capacity, tensile performance, and conductor weight. Compared with conventional AAC conductors made from pure aluminium, AL59 offers improved mechanical strength while maintaining good electrical conductivity.

Its excellent corrosion resistance makes it particularly suitable for overhead power networks in coastal regions and other demanding outdoor environments.

AL59 conductors are widely used in power distribution and transmission networks where electrical efficiency, mechanical reliability, and long-term service performance are important considerations.

For additional corrosion protection, grease filling can be applied during the stranding process according to project requirements.
