ACSR Cable (Aluminum Conductor Steel Reinforced) for Overhead Transmission

ACSR Cable (Aluminum Conductor Steel Reinforced) is a high-capacity, high-strength stranded conductor typically used in overhead power transmission and distribution lines. The outer strands are high-purity aluminum, chosen for their excellent conductivity, low weight, and low cost. The center strand or core is high-strength steel, which adds the mechanical strength needed to support the weight of the conductor over long spans.

At our factory, we manufacture premium ACSR conductors engineered to withstand harsh weather conditions, offering optimal electrical performance and exceptional mechanical strength for long-span power grid projects.

Key Features & Technical Advantages

• High Tensile Strength: The galvanized steel core enables higher mechanical tension and longer spans with less sagging.
• Excellent Conductivity: Premium grade aluminum outer layers ensure optimal electrical efficiency and reduced power loss.
• Corrosion Resistance: Coated with anti-corrosion grease or treated with zinc coating (Class A, B, or C galvanized) for prolonged outdoor service life.
• Cost-Effective: Combines the lightweight efficiency of aluminum with the economy of steel reinforcement, reducing line installation costs.

Standard Specifications & Parameters

We manufacture ACSR conductors in strict compliance with international standards including ASTM B232, IEC 61089, BS 215 and DIN 48204. Below are the specifications for standard sizes:

Note: Custom strandings, cross-sections, and specific structural requirements can be customized upon request.

Common Applications

• Overhead Power Distribution networks (Medium and Low Voltage overhead systems).
• Overhead Power Transmission lines (EHV/UHV grids).
• Long-span Crossings (Rivers, valleys, and rugged geographical terrains requiring high mechanical tension).
• Substation terminal connections.

Strict Quality Control & Testing

To ensure zero defects for high-voltage projects, every batch of ACSR wire undergoes rigorous testing in our certified labs before dispatch:

• Tensile Strength Test for both steel and aluminum wires.
• Electrical Conductivity Test to guarantee minimized power loss.
• Galvanizing Thickness Test to ensure robust weather resistance.
• Dimension and Visual Inspection according to international tolerance metrics.

Packaging & Delivery

We understand the logistics requirements for large-scale engineering. Our packaging ensures your cables arrive safely:

• Packaging Type: Treated wooden drums, steel-wooden drums, or full-steel drums.
• Drum Length: 500m, 1000m, 2000m per drum, or tailored to your logistics requirements.
• Marking: Clear side-labeling with conductor type, size, gross weight, net weight, and country of origin.

Frequently Asked Questions (FAQ)

Q1: What is the main difference between ACSR and AAC conductors?
A: ACSR contains a steel core for reinforcement, which makes it ideal for long-span overhead lines with high mechanical load. AAC (All Aluminum Conductor) has no steel core and is lighter but has lower tensile strength, mostly used for shorter spans in urban areas.

Q2: Can you provide third-party test reports for ACSR cables?
A: Yes, we provide SGS, BV, or Intertek inspection reports and inner mill test certificates (MTC) upon request to guarantee compliance with your local power grid standard.

Q3: What information should I provide to get an accurate quote?
A: Please provide the standard (e.g., ASTM, IEC), Code Name/Size (e.g., Raven, Dog), total quantity needed, and preferred port of delivery.
