Positioning Of Pre-stranded Wire In Power Transmission Networks

armor rods for acsr, as a connecting hardware used in overhead power lines and overhead optical cables, has long existed in conductor connections and transition nodes. armor rods transmission line originated in the mid-20th century and has gradually evolved into one of the indispensable metal spiral wires in systems engineering.

In a mature power system, stress concentration and physical friction occur at the conductor and joint locations. armour rod tightly engages with the conductor surface through its helical structure, forming a "transition bridge" at these nodes, which allows the conductor connection end to evenly distribute the load-bearing capacity and mechanical load. This structural design concept comes from long-term engineering practice and product evolution.

armour rod in transmission line exists not merely for connection, but also for "coordinating" the interface between the conductor and accessories. In complex environments, such as wind load vibration or thermal cycling load changes, it acts as a flexible intermediary between the conductor and surrounding hardware, preventing stress concentration at a single node.
