ACSR/TW/AW

Aluminum Conductor, Aluminum-Clad Steel Reinforced, Trapezoidal Wire Construction

Download PDF

Construction:

Core:Stranded aluminum-clad steel core, available in AW2 normal-strength and AW3 high-strength classes
Stranding:Hard-drawn aluminum (1350-H19) trapezoidal-shaped wires with 61.2% conductivity

Applications and Features:

ACSR/TW/AW (Aluminum Conductor, Aluminum-Clad Steel Reinforced, Trapezoidal Wire) is a compact conductor consisting of trapezoidal-shaped hard-drawn aluminum wires surrounding an aluminum-clad steel core. The aluminum strands provide electrical conductivity, while the aluminum-clad steel core provides mechanical strength, additional conductivity, and corrosion protection.

The trapezoidal-wire design increases packing efficiency, allowing either more aluminum within a given conductor diameter or a reduced diameter for a given aluminum area. Area-equivalent designs can reduce wind and ice loading, while diameter-equivalent designs can increase aluminum area and electrical capacity.

ACSR/TW/AW is suited for overhead transmission and distribution applications requiring the strength and proven performance of ACSR, the compact geometry of trapezoidal-wire construction, and the corrosion resistance of an aluminum-clad steel core.

Continuous operating temperature - 75°C
Emergency operating temperature - 100°C
