AACTW (Aluminum Alloy Conductor With Profile Wire)
AACTW (Aluminum Alloy Conductor With Profile Wire)
Product Overview
As a professionalbare conductor supplier,Hebei Yingshang Aluminum Industrymanufactures high-performanceAACTW conductor (Aluminum Alloy Conductor With Profile Wire)designed for modern overhead power transmission and distribution systems.
AACTW conductors are composed ofaluminium alloy special-shaped wiresthat 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 enhancedelectrical 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
TheAACTW conductoris 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 supportlong-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.
