SUMMARY
High voltage transmission lines, specifically those operating at 400kV, benefit significantly from the use of twisted steel strands combined with twisted aluminium strands. This construction method enhances flexibility and reduces the risk of fracture compared to using a single solid wire of equivalent cross-section. The combination leverages steel's strength and aluminium's superior conductivity, making it an optimal choice for modern electrical infrastructure.
