AACTW (Aluminum Alloy Conductor With Profile Wire)

AACTW (Aluminum Alloy Conductor With Profile Wire)
Product Overview
As a professional bare conductor supplier, Hebei Yingshang Aluminum
Industry manufactures high-performance AACTW conductor (Aluminum Alloy
Conductor With Profile Wire) designed for modern overhead power transmission
and distribution systems.
AACTW conductors are composed of aluminium alloy special-shaped wires that
have undergone advanced processing to form non-circular cross-sections, such as
trapezoid or special-shaped isosceles trapezoids. Compared with traditional
circular wires, these profiled wires offer enhanced electrical performance,
mechanical strength, and space utilization, making them ideal for urban
overhead lines, rural power grids, long-span cross-regional transmission lines,
and power grid renovation projects.
 
Conductor Structure
The AACTW conductor is typically made of multiple aluminium alloy single
wires twisted concentrically:

Outer Layers: Special-shaped aluminium alloy wires arranged in concentric
layers, forming a uniform and tightly packed conductor.


Wire Profile: Each special-shaped wire features an isosceles trapezoid cross-
section with a circular arc base, providing improved packing density and
mechanical performance.


Center Core: Standard aluminium alloy circular wires or specially designed
profile wires maintain overall conductor integrity and electrical uniformity.

This structure ensures efficient conductivity, high tensile strength, and
optimized space utilization, reducing the overall conductor diameter without
compromising performance.
 
Core Performance Advantages
High Mechanical Strength
The aluminium alloy material inherently provides high tensile strength. Special
shaping technology further enhances the strength of the conductor core,
allowing it to withstand greater tension and support long-span overhead
transmission lines.
Excellent Conductivity
Through precise alloy design and shaping technology, AACTW conductor achieves
stable conductivity suitable for medium and high-voltage transmission. Under
comparable current carrying capacity, AACTW is significantly lighter than
copper conductors, reducing tower load and installation complexity.
Optimized Space Utilization
The profiled wire design allows a tighter packing of strands, reducing
conductor diameter and increasing current density per unit area. This improves
thermal performance, mechanical stability, and overall power transmission
efficiency.
