556.5-20/7 TYPE 16 DOVE/TW ACSR/TW

Southwire #: 36577501

Used for bare overhead transmission, 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 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

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
