Material Reaction Of Pre-twisted Wire Under Temperature Fluctuations

The physical properties of component armor rods for acsr, composed of multiple strands of high-strength steel wire twisted together and subjected to stress relief treatment, change under different ambient temperatures. These changes directly affect the prediction of finished product performance and the parameter settings for engineering design.

armor rods transmission line exhibits different stress relaxation behavior at temperatures significantly below room temperature compared to its room temperature state. As the temperature decreases, the stress relaxation rate of armour rod changes in the initial stage, and this trend shows a certain regularity at extremely low temperatures.

As the temperature rises to a certain range, the tensile strength, yield strength, and other mechanical properties of component armour rod in transmission line gradually weaken. Simultaneously, the influence of load conditions on temperature effects needs to be considered during the design phase.
