What Changes Will Occur In The Stress Conditions Faced By Railway Cross-line Pre-twisted Wires?

When the railway speed increases, the stress conditions faced by the railway cross-line armor rod preformed will change. This requires the design and performance of preformed armour rod to be optimized to adapt to the new operation requirements. For example, as the train speed increases, the external forces such as aerodynamics on the contact network increase. armor rods must be able to withstand greater forces, while ensuring the stability of the armor rods for acsr connection to avoid affecting the normal operation of the train.
