AAAC (Aluminum Conductor With Profile Wire)
Product Overview
As a trusted bare conductor supplier, Hebei Yingshang Aluminum Industry manufactures high-performance AAAC conductor (Aluminum Conductor With Profile Wire) designed for medium- and high-voltage power transmission and distribution projects.
These conductors are made by drawing high-purity aluminium into non-circular cross-section single wires through precision molds and then assembling them with concentric twisting technology. The resulting profile optimizes the conductor's cross-sectional structure, minimizing gaps and improving space utilization. This makes AAAC conductors ideal for urban high-voltage networks, rural distribution lines, high-altitude transmission, compact bus ducts, and special power grid scenarios where efficiency, low loss, and reliability are critical.
Conductor Structure
Monofilament Profile:
Single wires feature non-circular shapes such as trapezoid, fan-shaped, Z-shaped, or semi-circular, with trapezoidal and fan-shaped being the most widely used.
Twisting Method:
Irregular single wires are arranged concentrically from the center outward.
Outer layer strand count increases with conductor size.
Twist pitch is reduced compared with circular wires, preventing strand slippage and improving mechanical stability.
Benefits of Profile Wire Structure:
High space utilization (gaps between strands only 3â??5%)
Conductive cross-section 10â??15% larger than equivalent round wires
Compact design reduces conductor diameter while maintaining performance
