AAC Conductors (AAC)
All Aluminium Conductor (AAC) are concentric-lay-stranded overhead conductors manufactured from high-purity electrolytic grade aluminium — optimised for overhead power transmission and distribution.
What are AAC Conductors?
All Aluminium Conductor (AAC) are concentric-lay-stranded overhead conductors manufactured from high-purity electrolytic grade aluminium — optimised for overhead power transmission and distribution.
AAC conductors consist entirely of aluminium strands, offering excellent electrical conductivity, corrosion resistance, and light weight. The conductors are manufactured from EC-grade aluminium (99.7% minimum purity) conforming to IS 398: Part 1: 1996, making them ideal for overhead lines in urban and suburban environments where span lengths are moderate and corrosion is a primary concern.
At Mahavir Transmission Limited, every AAC conductor is produced under strict quality controls using precision wire-drawing and stranding technology. Our conductors are designed to deliver consistent electrical performance, dimensional accuracy, and long service life even under demanding environmental conditions.
The superior conductivity-to-weight ratio of AAC makes it the preferred choice for urban distribution networks, coastal regions, and electrification projects under Central and State Government programs.
EC Grade Aluminium
Minimum 99.7% pure electrolytic grade aluminium ensures superior electrical conductivity and excellent corrosion resistance.
Concentric-Lay Stranded
Multiple strands laid in concentric layers provide enhanced mechanical flexibility, ease of handling, and reliable long-term performance.
Weather & Corrosion Resistant
Inherent aluminium oxide layer provides natural protection against atmospheric and corrosion making it suitable for coastal areas.
Lightweight Design
Low self-weight reduces structural loading on towers and poles, enabling longer spans and lower civil infrastructure costs.
Key Technical Features
Engineered for performance, reliability, and long-term value in overhead transmission and distribution infrastructure.
High Electrical Conductivity
EC-grade aluminium achieves a minimum of 61% IACS (International Annealed Copper Standard) conductivity, ensuring low resistive losses and efficient power transfer across distribution networks.
Low Self-Weight
Approximately one-third the weight of copper – significantly reduces tower and pole loading, lowers structural costs, and simplifies installation.
Excellent Corrosion Resistance
Natural aluminium oxide film offers inherent protection against environmental degradation, making AAC an ideal choice for coastal and high-humidity regions.
Flexible & Easy to Handle
Stranded construction provides high flexibility for easy installation, tensioning, jointing, and termination, reducing labour time on site.
Fully Recyclable
100% recyclable aluminium material supports sustainable infrastructure development and reduces lifecycle carbon footprint significantly.
Low Maintenance
Durable construction with no galvanic corrosion concerns between strands, minimizing inspection frequency and maintenance cost over the service life.
Wide Range of Sizes
Available from 10 mm² to 1000 mm² nominal area, covering LV, MV and HV distribution requirements across all project scales.
Wide Temperature Range
Rated for continuous operation at upto 75°C (conductor temperature), suitable for high-ambient tropical conditions prevalent across India.
Applications of AAC Conductors
AAC conductors from Mahavir Transmission are trusted across the full spectrum of power delivery infrastructure in India and beyond.
Urban Distribution Networks
Ideal for urban and semi-urban overhead distribution networks operating at 11 kV, 33 kV, and 66 kV, where moderate span lengths, high electrical conductivity, and excellent corrosion resistance are essential.
Coastal & High Humidity Zones
Superior resistance to salt-laden atmospheric corrosion makes AAC the conductor of choice for coastal regions and humid tropical environments worldwide.
Renewable Energy Projects
Widely used in solar park transmission systems, wind farm collector networks, and renewable energy distribution projects requiring high conductivity performance.
Rural Electrification
Extensively deployed for last-mile electrification projects in rural and semi-urban areas worldwide.
Industrial & Estate Feeders
Used for overhead power supply lines in industrial estates, special economic zones, and large commercial facilities requiring reliable, low-loss power transmission.
EPC Transmission Projects
Supplied to leading EPC contractors for overhead line projects under national grid utilities, power transmission companies, and state transmission projects worldwide.
