ACSR (Aluminum Conductor Steel Reinforced) is a widely used overhead conductor consisting of concentrically stranded aluminum wires on a galvanized steel core. The aluminum strands provide excellent conductivity, while the steel core adds mechanical strength and durability. ACSR conductors are ideal for medium and high voltage transmission and distribution systems where long spans, high tension, and mechanical reliability are required.

Application

  • Overhead power transmission and distribution lines

  • Primary and secondary distribution circuits

  • Messenger support for aerial cable installations

  • Ideal for river crossings, valleys, and other long-span installations

  • Frequently used in rural electrification and grid expansion projects

Key Features

  • ✅ High Strength-to-Weight Ratio: Suitable for long spans and high mechanical loads

  • ✅ Excellent Electrical Conductivity: Aluminum 1350-H19 strands provide efficient current carrying capacity

  • ✅ Rugged Construction: Galvanized steel core ensures superior tensile strength and corrosion resistance

  • ✅ Low Sag Performance: Enables tighter tensioning and reduced line sag

  • ✅ Cost Effective: Combines performance and economy for utility-scale installations

  • ✅ Proven Performance: Complies with DIN 48204 and other international standards for overhead conductors

Construction Details

ACSR is a composite concentric-lay stranded conductor made up of:

  • Central Core: One or more galvanized steel wires (can be single or stranded – e.g., 1, 7, 19, or 37 wires)

  • Outer Layers: One or more layers of hard-drawn aluminum wires (Al 1350-H19) helically stranded over the steel core

Component Material
Conductor Aluminum 1350-H19
Core Galvanized steel (Class A/B/C zinc coating)
Stranding Options 6Al/1St, 12Al/7St, etc., per DIN 48204
Direction of Lay Right-hand or left-hand, per specification

Manufacturing Standard

  • DIN 48204 – German standard for ACSR conductors

  • Also available to IEC 61089, ASTM B232, BS 215-2, or other custom standards upon request

Technical Advantages

  • Longer spans with fewer towers

  • Higher mechanical strength for adverse weather conditions

  • Good corrosion resistance in standard environments (can be enhanced with zinc/aluminum alloy-coated steel)

  • Widely accepted and installed by utilities, contractors, and EPCs globally
