ACSR/TW Conductor

Overview

Parameter Inquiry

Overview

APPLICATIONS

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.

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.

SPECIFICATIONS:

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
