4 Rose All Aluminum Conductor AAC

Allowable Ampacity for 4 Rose All Aluminum Conductor AAC: 138 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.

Also Known As:

4 rose all aluminum conductor, 4 rose all aluminum conductor table, 4 rose aac all aluminum conductor, 4 rose aac cable, 4 rose aluminum alloy cable, 4 rose abrasive resistant cable, 4 rose transmission overhead, 4 rose overhead power line components.

Standards:

• 1350-H19 for Electrical Purposes 

• Concentric-Lay-Stranded Aluminum 1350 conductors 

• Requirements of the National Electrical Code 

• ASTM B-230 & B-23

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
