One of our offerings at Peak Substation Services is the all-aluminum conductor (AAC), primarily used in overhead power transmission and distribution lines. As the name suggests, this conductor’s main composition is aluminum. All the stranded wire or conductors inside it consist of the same material. In addition, the cables are used for electrical purposes without any external insulation, so they're ideal for your bare overhead applications.
Here are some valuable details about the All Aluminum Conductor to inform your buying decision.
Applications of the All Aluminum Conductor (AAC)
AAC wire consists of stranded conductors made from 99.7 percent pure aluminum. These inherent attributes, alongside the wire's homogeneous construction, optimize its corrosion resistance. In addition, AAC wire ampacity is impressive, boasting a 61.2 percent International Annealed Copper Standard (IACS) minimum conductivity. Their lighter weight makes the all aluminum conductor the best option for structures that don't require high tensile strength.
Typical applications of AAC cables include:
- Metro and railway utility industries
- Wood poles
- Urban areas and city power lines
- Coastal overhead power lines that face the constant threat of corrosion
Specifications
AAC is an economical bare overhead conductor that aligns with the following ASTM (American Society for Testing and Materials) standards:
The wire is made of an aluminum 1350 alloy in the H19 temper, representing a hard, strain-hardened aluminum alloy. 
The conductor features aluminum 1350 concentric lay strands.Construction
AAC's sturdy construction makes it one of the most sought-after conductors. First, the fabricating wire is extracted from top-tier quality rods through cold drawing (annealed or hard). This aluminum alloy 1350 wire is concentrically stranded to form a spiral wrap around a central wire.
Each additional layer consists of six more wires than the one beneath. The outermost layer exhibits a right-hand lay, which reverses in subsequent layers.
This aluminum conductor AAC design results in the most economical bare overhead conductor. Besides the affordable AAC wire price and its lighter weight, these conductors use simpler fittings and are easier to handle during installation. Furthermore, the homogeneous construction makes the AAC wire remarkably corrosion-resistant.
AAC Wire Variants
AAC variants include:
Rose, Nasturtium, Marigold, Hawthorn, Violet, Narcissus, SneezewortPoppy, Aster, Dahlia, Trillium, Valerian, Phlox, Magnolia, Jessamine, Canna, Goldentuft, Mistletoe, Meadowsweet, Orchid, Petunia, Snapdragon, Bluebell, Laurel, Daisy, Carnation, Lupine, Cockscomb, Larkspur, Oxlip, Cowslip, Camellia, Hawkweed, Sagebrush, Lilac, Peony, Tulip, Goldenrod, Gladiolus, Arbustus, Iris, Pansy, Columbine, Syringa, Cosmos, Zinnia, Flag, Daffodil, Coreopsis, Heuchera, Varbena, Cattail, Bitterroot, Hyacinth, Bluebonnet.
All these AAC variants have unique attributes, and it can be difficult to get what's right for your project. Fortunately, you can narrow your options by taking these factors into consideration:
The first consideration is the conductor's size and cross-sectional area. This decision should be based on the current carrying capacity you need for your application. Rose has the smallest sectional area, measuring 21.10 mm2, while Bluebonnet is the largest at 1,773 mm2. The conductor's size affects its electrical and mechanical performance.
AAC is widely known for its electrical conductivity. Before choosing, consider your application's required electrical resistance and current-carrying capacity. Generally, resistance is inversely proportional to the wire's area. That's why Bluebonnet has the lowest resistance of 0.0166 ohm/km while Rose has the highest at 1.3620 ohm/km.
Depending on your environment, you may need a conductor with adequate mechanical strength to withstand wind, ice, and other heavy materials. The value decreases as you increase the sectional area. Rose has the lowest mechanical strength level, at 3.91 kN, while Bluebonnet's stands at 261 kN.
Select a conductor with the appropriate voltage rating to meet the ASTM requirements for your application.
Your budget is another key determinant, and you should consider the cost of the conductor, including installation and maintenance costs. Generally, AAC conductors are often more cost-effective than alternatives like copper conductors.
Ensure the conductor meets the relevant electrical standards for safety and reliability. The last thing you want to deal with mid-project are accidents and injuries from non-compliant conductors. High-standard conductors also allow you to enjoy reliable operations and less downtime.
You should also consider the environmental impact of the conductor, including its recyclability and sustainability. Fortunately, all AAC conductors have remarkable recyclability. In addition, they have a low environmental footprint.
It's always wise to choose a reputable manufacturer or supplier with a track record of providing high-quality AAC conductors. 
Lastly, consider the expected lifespan of the conductor and how it will perform over time. This attribute is especially important for long-term utility applications. Generally, AAC conductors are corrosion-resistant, which extends expected service life.The PEAK Difference
