Application

Used as bare overhead transmission cable and as primary and secondary distribution cable. A good strength-to-weight ratio makes ACAR applicable where both ampacity and strength are prime considerations in line design; for equal weight, ACAR offers higher strength and ampacity than ACSR.

Standards & References

Southwire's ACAR bare conductor meets or exceeds the following ASTM specifications:

  • B230 Aluminum 1350-H19 Wire for Electrical Purposes.
  • B398 Aluminum-Alloy 6201-T81 Wire for Electrical Purposes.
  • B524 Concentric-Lay-Stranded Aluminum Conductors, Aluminum-Alloy Reinforced (ACAR, 1350/6201).

Construction

Aluminum 1350-H19 wires, concentrically stranded about an aluminum-alloy 6201-T81 core. Although the alloy strands generally comprise the core of the conductor, in some constructions they are distributed in layers throughout the aluminum 1350-H19 strands.
