PRODUCT OVERVIEW

What are High Performance Conductors ?

High Performance Conductors (HPC) are advanced overhead conductors developed to deliver superior electrical and mechanical performance compared to conventional conductors. These conductors typically include Composite Core Type, ACSS, Invar and Gap Conductors designed for higher ampacity, lower sag, and improved thermal performance.

High Performance Conductors are manufactured using advanced Aluminum alloys and specialized core materials such as composite cores, Invar cores, steel cores, and gap-type core designs. These advanced materials enable the conductor to operate at elevated temperatures while maintaining low sag, high tensile strength, and stable mechanical performance.

At Mahavir Transmission Limited, High Performance Conductors are manufactured using advanced production technologies, stringent quality control systems, and precision testing methods to ensure consistent quality and dependable long-term field performance.

With their superior thermal capability, higher current carrying capacity, and reduced sag characteristics, High Performance Conductors are particularly suitable for transmission line uprating, renewable energy evacuation, urban transmission corridors, congested right-of-way areas, and modern grid expansion projects.
