summary

Aluminium Conductors – Galvanized Steel Reinforced (ACSR) for Extra High Voltage are overhead transmission conductors designed for 400 kV and above power lines. They consist of aluminum strands surrounding a galvanized steel core, combining high electrical conductivity with mechanical strength for long-distance, high-capacity power transmission.

Why BIS Certificate is Mandatory for Aluminium Conductors- Galvanized Steel –Reinforced for Extra High Voltage (400 kV and above), for Overhead Transmission Purposes

BIS certification is mandatory to ensure safety, strength, conductivity, and performance reliability of ACSR conductors used in extra high voltage transmission lines. These conductors operate under extreme electrical and environmental conditions, and BIS standards help prevent failures, power losses, accidents, and ensure compliance with Indian regulatory requirements.

What is BIS Certified for Aluminium Conductors- Galvanized Steel –Reinforced for Extra High Voltage (400 kV and above), for Overhead Transmission Purposes

The BIS certified specification defines requirements for construction, aluminum and steel wire quality, tensile strength, electrical resistance, galvanization, stranding, and testing procedures. It ensures the conductor meets Indian Standards for mechanical load capacity, corrosion resistance, conductivity performance, and durability in overhead extra high voltage transmission systems.
