ACSR Conductorsfor Strength-Critical Overhead Lines
Aluminium Conductor Steel Reinforced conductors built to combine aluminium current carrying capacity with the mechanical strength of a galvanized steel core.
Key Benefits
Combining aluminium current capacity with mechanical steel strength.
ACSR conductors are bimetallic stranded conductors used where transmission and distribution lines need a strong balance of current capacity, mechanical strength, and span performance.
High tensile strength
Steel reinforcement supports longer spans and demanding route conditions.
Efficient current carrying
Aluminium outer strands provide conductivity with manageable conductor weight.
Flexible design
Aluminium-to-steel proportions can be selected for the project requirement.
EHV suitability
Brochure includes ACSR for extra high voltage above 400 kV as per IS 398 Part 5.
Proven line format
Widely used in overhead transmission and distribution networks.
Broad range
The brochure includes multiple standard code-name sizes from distribution to transmission applications.
Conductor Build-Up
Bimetallic strength, controlled into a dependable conductor.
The ACSR profile is built around high-purity aluminium outer strands and a galvanized steel core, validated against recognized conductor requirements.
Galvanized steel core
Galvanized steel core
