Product Description

Product Description

I. Description

ACSR (Aluminum Conductor Steel Reinforced) combines 99.6% pure aluminum strands for optimal conductivity (61% IACS) with galvanized high-carbon steel cores (1,250-1,850 MPa tensile strength). Ideal for 35-1000kV power grids, it reduces tower spacing by 40% in coastal/mountainous areas while complying with GB/T 1179-2008 and IEC 61089 standards.


II. Product Overview

ACSR conductors integrate multi-layer aluminum strands helically wound over a galvanized steel core. This hybrid design leverages aluminum's conductivity for efficient power transmission and steel's mechanical strength to support spans exceeding 500 meters. Certified for -30°C to 120°C operations, it minimizes energy loss (<0.1209 Ω/km) and resists corrosion in coastal/industrial environments. Widely used in power grids, railways, and telecom infrastructure.

Core Selling Points

1. Dual-Material Performance Optimization
   • Aluminum Layer: 99.6% pure strands for 61% IACS conductivity, reducing energy loss by 35% vs. pure aluminum cables.
   • Steel Core: Galvanized high-carbon steel (G2A/G3A grades) with 1,850 MPa tensile strength, preventing sag in extreme loads.
2. Environmental Resilience
   • Triple-layer anti-corrosion coating withstands salt spray, humidity, and industrial pollutants (>500 hours salt-spray resistance).
   • Operational range: -30°C to 120°C, suitable for Arctic grids and desert solar farms.
3. Engineering Efficiency
   • Reduces tower spacing by 40% due to high strength-to-weight ratio, lowering infrastructure costs.
   • Four-/six-bundle configurations for 500kV+ transmission lines, optimizing space and load distribution.
4. Sustainability & Compliance
   • Aluminum is 100% recyclable; manufacturing consumes 30% less energy vs. copper cables.
   • Certifications: RoHS 3.0, GB/T 1179-2008, IEC 61089.

IV. Product Description

1. Structural Engineering for Extreme Loads
The galvanized steel core (G2A/G3A grades) provides 1,850 MPa tensile strength, resisting deformation under ice/wind loads. Outer aluminum strands (0.05-12mm diameter) are helically wound with ±0.02mm precision to ensure uniform stress distribution, eliminating strand displacement in high-wind zones.

2. Electrical Performance Optimization

• Skin Effect Utilization: Current flows primarily through the aluminum layer, reducing impedance by 15% and energy loss by 4-6% vs. standard ACSR.
• Low DC Resistance: Ranges from 0.7426 Ω/km (117.4mm²) to 5.415 Ω/km (15.78mm²), enhancing transmission efficiency.

3. Environmental Resilience & Application

• Corrosion Defense: Zinc plating (ASTM B633) and aluminum oxide layer protect against marine/industrial corrosion, extending lifespan to 30+ years.
• Critical Use Cases:
  • Power Distribution: Deployed in 500kV+ overhead lines across mountainous regions (e.g., Three Gorges Grid).
  • Railways & Telecom: Ensures uninterrupted conductivity in high-vibration environments (e.g., high-speed rail catenaries).
