477 MCM Hen ACSR TW Aluminum Conductor Steel Reinforced Trapezoidal Wire

477 MCM Hen ACSR TW Aluminum Conductor Steel Reinforced Trapezoidal Wire

Applications:

ACSR/TW – shaped wire compact concentric lay-stranded aluminum conductor steel reinforced – conductors with equal area or equal diameter designs, as compared to standard ACSR conductors, and various steel core coatings to address your application requirements for transmission and distribution projects.

Also Known As:

477 MCM ACSR TW Aluminum Cable,  Aluminum Reinforced Cable, Steel Reinforced Cable, 477 MCM ACSR TW Cable, Aluminum Trapezoidal Wire, 477 MCM ACSR TW Aluminum Conductors.

Features:

• 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

Standards:

• 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
