Overhead lines

Power Overhead lines

  • Aluminum conductor, steel or composite reinforced, all aluminum alloy conductors, and other overhead conductors.
  • New thermo-resistant conductors operate up to 220°C without increasing sag, and reducing tension on towers.
  • Nexans has also developed a new generation of insulated aerial lines.


Nexans provides an increasing number of power utilities worldwide with high temperature HV conductors, which allow higher transmission capacities compared to traditional conductors. Also, to prevent the theft of electricity in Argentina and Brazil, Nexans designed a concentric “anti-robbery” cable which has allowed power utilities to recoup 15% of lost output.

Special design of wires in "Z" or trapezoidal shape instead of the standard round wires.

The main advantage is the less voids among wires increasing the conductivity by 15% to 18% of the conductor considering the same diameter.

Additionally, the AeroZ with "Z" shape wires has a better aerodinamic performance with lower wind drag coefficient, that means, less mechanical efforts transmitted to the structures due to the wind load.
