All Aluminum Alloy Conductor (AAAC) was developed to fulfill the requirement of an economical conductor for overhead applications requiring higher strength than what was reachable with 1350 grade aluminum conductors, but without a steel center. It is used as a bare overhead conductor for primary and secondary distribution.
Concentric lay stranded All Aluminum Alloy Conductors are made out of high strength Aluminum-Magnesium-Silicon Alloy. AAAC is supplied with several variations of electrical grade combination types: 6101 and 6201. AAAC is produced using one or more strands of hard drawn 1350 aluminum composite. The high strength to weight ratio given by the 6201-T81 composite makes the homogeneous development of AAAC conductors a favored decision for transmission and distribution ventures where a conductor with more strength than AAC is required, a conductor with comparable strength than ACSR is favored and where a higher corrosion resistance than ACSR is needed.
These conductors are designed to get better strength to weight ratio and offer enhanced electrical properties including but not limited to: excellent sag-pressure qualities, and prevalent corrosion resistance when contrasted and ACSR. When compared with a routine ACSR transmitter, the lighter weight, relative strength and current carrying capacity, lower electrical losses and predominant corrosion resistance have given AAAC a wide recognition in the distribution of medium and high voltage transmission lines. In fact, AAAC has the best strength to weight ratio amongst all bare overhead cables.
Product Highlights:
• AAAC conductor is a concentric lay stranded conductor consisting of Aluminum Alloy 6201-T81 wires, similar in appearance to a 1350 grade aluminum conductor.
• DC resistance at 20°C of the 6201-T81 alloy has a greater resistance to abrasion than conductors of 1350-H19 grade aluminum.
• Available in both single and multi-layer constructions
Technical Standards:
• B-398 Aluminum-alloy 6201-T81 round wire which are solution heat-treated, cold worked, and artificially aged for electrical purposes.
• B-399 Concentric-lay-stranded conductors, made from round aluminum-alloy 6201-T81 (hard: solution heat-treated, cold worked, and then artificially aged) wires, for use for electrical purposes.
