A new generation of high performance conductors

In this paper, a new generation of overhead conductors is introduced based upon a fundamental change in the type of material used. The conductors, referred to as composite conductors or ACCR (aluminum conductor composite reinforced) relies upon a core made from composite wires surrounded by high temperature aluminum wires. This material has been specifically developed for high temperature overhead conductor applications and offers a range of attractive properties including reduced thermal expansion characteristics, improved strength to weight ratio and conductivity improvements.
