AAC, AAAC & ACSR - Aluminum and Aluminum Alloy Stranded Conductors

Product Standards
Our R&D and manufacturing processes strictly adhere to national and authoritative industry standards to ensure long-term operational reliability in extreme climatic environments:
National Standard: Fully compliant with GB/T 1179-2017 (*Round wire concentric lay overhead electrical stranded conductors*).
Other Specifications: Meets specialized technical agreements for power systems and relevant international standards.

Model Classification and Structural Features
This series offers a diversified range of structural combinations to address varying span and load requirements:
Aluminum Stranded Conductor (AAC / JL): Composed of hard-drawn aluminum wires. Featuring lightweight properties and high conductivity, it provides an economical solution for short-span lines.
Aluminum Alloy Stranded Conductor (AAAC / JLHA1 & JLHA2): Utilizes high-performance aluminum alloy materials. Its tensile strength is significantly superior to pure aluminum, complemented by excellent creep resistance.
Aluminum Conductor Steel Reinforced (ACSR / JL/G1A-G3A): Features a core of high-strength galvanized steel wires surrounded by one or more layers of aluminum wires. The steel core provides the primary tensile strength while the aluminum layers handle current transmission, making it the mainstream choice for long-span lines.
Advanced Derivatives: Includes specialized models such as Aluminum-clad Steel Reinforced, Aluminum Alloy Conductor Aluminum Alloy Reinforced, and various lightweight-enhanced conductors.

Corrosion Protection for Harsh Conditions
For rigorous operating environments, we provide specialized protection schemes:
Anti-Corrosion Treatment: Conductors (Anticorrosive ACSR) can be uniformly coated with anti-corrosive grease within the steel core gaps or on the aluminum wire surfaces to form a physical protective barrier.
Environmental Adaptability: This solution significantly extends the service life of conductors in areas prone to coastal salt spray, industrial atmospheric pollution, and heavy icing.

Operating Characteristics & Performance Advantages
Superior Mechanical Tensile Strength: The ACSR series offers an extremely high Rated Tensile Force (RTF), capable of withstanding significant self-weight loads and natural stresses such as wind and snow.
Low Loss & High Conductivity: The DC resistance of the conductor is strictly controlled according to GB/T standards, effectively reducing energy loss and heat accumulation during high-current transmission.
Optimized Surface Characteristics: The stranded surface is smooth and uniform, which effectively minimizes corona loss and electromagnetic interference during high-voltage operation.
Excellent Installation Flexibility: The scientifically compact stranded structure facilitates efficient on-site stringing, tensioning, and subsequent maintenance operations.

Core Application Areas
Cross-Regional Transmission Grids: Due to its high-strength characteristics, ACSR is widely utilized in High-Voltage and Ultra-High Voltage (UHV) transmission trunk lines.
Urban and Rural Distribution Networks: AAC and AAAC are ideal for urban distribution projects where tower load limits are strictly regulated.
Special Crossing Projects: Provides customized high-strength conductor solutions for challenging constructions, such as river crossings and deep valley long-span lines.
