Aerial Bunched Cables (AB-CABLES)
High-performance insulated overhead cable system designed for safe, reliable, and efficient low and medium voltage power distribution networks.
What are Aerial Bunched Cables ?
Aerial Bunched Cables (ABC) are compact overhead cable systems consisting of insulated aluminium conductors twisted together around a supporting messenger wire or neutral conductor. The insulated construction minimizes the possibility of short circuits caused by contact with trees, birds, or accidental external interference, while significantly reducing technical losses and power theft.
ABC systems are widely used in overhead distribution networks where safety, reliability, and space optimization are critical. Their compact design allows installation in congested urban areas, narrow streets, forest corridors, coastal regions, and locations where bare conductor systems are vulnerable to frequent faults and interruptions.
Manufactured in accordance with relevant Indian and international standards, Aerial Bunched Cables provide excellent electrical performance, high mechanical strength, and superior resistance to UV radiation, moisture, and environmental contaminants. The insulated design also improves public safety and reduces maintenance requirements throughout the service life of the network.
At Mahavir Transmission Limited, Aerial Bunched Cables are manufactured using advanced conductor stranding, triple-layer extrusion, and precision insulation technologies under rigorous quality assurance systems. This ensures uniform insulation thickness, excellent dimensional accuracy, and dependable long-term performance under demanding operating conditions.
With enhanced safety, reduced outages, lower maintenance costs, and improved network efficiency, Aerial Bunched Cables are an ideal solution for modern overhead distribution systems requiring reliable and uninterrupted power delivery.
