997.2-20/7 TYPE 13 ACSR/TW/GA2 ONTARIO 4921 FT

Southwire #: 62438416

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

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