AAC (All Aluminium Conductor) used primarily for overhead transmission and primary and secondary distribution, where ampacity must be maintained and a lighter conductor (compared to ACSR) is desired, when conductor strength is not a critical factor. Classes B and C are used primarily as bus, apparatus connectors and jumpers, where additional flexibility is required.

Bare conductor meets or exceeds the following ASTM specifications:

• B230 Aluminium 1350-H19 Wire for Electrical Purposes

• B231 Concentric-Lay-Stranded Aluminium 1350 Conductor
