250 Sneezewort All Aluminum Conductor AAC
Allowable Ampacity for 250 Sneezewort All Aluminum Conductor AAC: 425 Amps
Applications:
AAC, or All Aluminum Conductor, is an electrical cable mainly used for distribution services as well as overhead transmission in outdoor premises due to the high-quality water-resistant aluminum conductor. The AAC cable can be of two classes: class AA cables are with bare conductors to be used in overhead lines, and class A is for an electrical wire with both bare conductors for increased flexibility and conductors with a weather-resistant cover.

Application:
AAAC – All Aluminum Alloy Conductor is used for primarily and secondary overhead transmission and distributionservices. AAAC conductor is designed utilizing a high-strength aluminum alloy to achieve a high strength-to-weight ratio and better sag characteristic. AAAC conductor has a higher resistance to corrosion than ACSR.
Conductors:
AAAC conductor is a concentric lay stranded conductor consisting of Aluminum Alloy 6201-T81 wires, similar in appearance to a 1350 grade aluminum conductor.
Notes:
DC resistance at 20°C of the 6201-T81 alloy has a greater resistance to abrasion than conductors of 1350-H19 grade aluminum.
Standards:
- ASTM B-398 & B-399
- Requirements of the National Electrical Code
