AAAC (All Aluminium Alloy Conductors)

AAAC (All Aluminium Alloy Conductors)
Product Overview
As an experienced bare conductor supplier, Hebei Yingshang Aluminum
Industry manufactures high-quality aaac conductor (all aluminium alloy
conductor) for modern overhead transmission and distribution systems. AAAC
conductors are widely applied in medium to high-voltage power lines, regional
distribution networks, and renewable energy grid-connection projects where
corrosion resistance, mechanical strength, and long-term reliability are
critical.
Produced from heat-treated aluminium alloy (commonly 6201 or equivalent), AAAC
conductor offers a well-balanced combination of strength, conductivity, and
lightweight design. Compared with traditional AAC and steel-reinforced
conductors, AAAC provides improved tensile performance and superior resistance
to environmental corrosion, making it a proven solution for utilities, EPC
contractors, and power grid operators worldwide.
 
Core Characteristics of AAAC Conductor
High Mechanical Strength
AAAC conductor is manufactured using high-strength aluminium alloy wire,
providing significantly higher tensile strength than pure aluminium conductors.
This allows the conductor to withstand greater mechanical tension and supports
longer spans, making it suitable for complex terrain, urban networks, and
demanding installation environments.
Reliable Electrical Conductivity
Although aluminium alloy has slightly lower conductivity than pure
aluminium, all aluminium alloy conductor still delivers excellent electrical
performance that fully meets overhead power transmission requirements. Its
optimized strength-to-conductivity ratio ensures efficient and stable power
delivery.
Excellent Corrosion Resistance
Aluminium alloy naturally resists atmospheric corrosion and does not rust. AAAC
conductor is particularly suitable for coastal areas, industrial pollution
zones, and high-humidity environments, where steel-cored conductors may suffer
from accelerated degradation.
 
Electrical Performance
For circular aluminium alloy wires with the same nominal cross-sectional area,
DC resistance at 20 °C varies according to conductor size—larger cross-
sections result in lower DC resistance.
Each AAAC conductor is designed with a defined current-carrying capacity
based on alloy composition and conductor cross-section.
For example, a 25 mm² aluminium alloy conductor typically supports a current
of approximately 110 A under standard operating conditions.
These electrical characteristics ensure consistent transmission performance
across different voltage classes and load conditions.
