Application

  • Used for bare overhead transmission, and primary and secondary distribution.
  • Two design offerings: Equal Area or Equal Diameter when compared to standard round ACSR
  • Equal area designs allow comparable ampacity in a smaller diameter conductor when compared to a standard round ACSR.
  • Equal diameter designs allow more ampacity and strength in an equal diameter conductor when compared to a standard round ACSR.

Standards & References

  • ASTM B230 Aluminum 1350-H19 Wire for Electrical Purposes
  • ASTM B498 Zinc-Coated (Galvanized) Steel Core Wire for Use in Overhead Electrical Conductors
  • ASTM B500 Metallic Coated or Aluminum Clad Stranded Steel Core for Use in Overhead Electrical Conductors
  • ASTM B779 Shaped Wire Compact Concentric-Lay-Stranded Aluminum Conductors, Steel-Reinforced (ACSR/TW)

Construction

  • Aluminum 1350-H19 trapezoidal-shaped wires, concentrically stranded about a steel core. Standard core wire coating for ACSR is Class A galvanized (GA2).
  • Also available in zinc-5% aluminum-mischmetal alloy coating or aluminum-clad (AW)
  • Additional corrosion protection is available through the application of grease to the core or complete conductor.
  • Also available in non-specular
