Aluminium Conductor Steel Reinforced (ACSR)

Why Choose Us?

Combining the high conductivity of aluminium with the tensile strength of a galvanized steel core, our ACSR conductors deliver low-sag performance and mechanical resilience, ideal for everything from local distribution to long-span transmission lines.

Optimal Strength-to-Weight

Aluminium strands helically stranded around a steel core ensure superior mechanical support with minimal weight penalty.

High Conductivity

 Pure aluminium outer layers provide excellent electrical performance and low DC resistance.

Low Sag & Creep Resistance

 Steel reinforcement and controlled alloy composition minimize elongation under load.

Durable & Weather-Resistant

 Galvanized steel core resists corrosion; aluminium sheath endures UV, moisture, and industrial pollutants.

Wide Temperature Range

Maintains performance from +90 °C, with short-circuit tolerance above 150 °C.

Versatile Sizes

 Available from small-scale “Weasel” conductors to heavy-duty “Dog”— custom lengths on request.

Applications

  • Overhead distribution in urban and rural grids
  • Long-span crossings (rivers, valleys) where tower loading is critical
  • Railway electrification and tramway feeders
  • Industrial power feeds and campus networks
  • Retrofit projects upgrading existing lines for higher loads

Applicable Standards

  • IS 398 Part 2 – ACSR with galvanized steel core for overhead lines
  • IEC 61089 – Round-wire, concentric-lay overhead electrical conductors
  • ASTM B232 – Specification for ACSR galvanized steel core
  • BS EN 50183 – ACSR with galvanized steel core for overhead lines
