How Do Pre-stranded Wires Provide Mechanical Protection For Conductors And Reduce Stress Concentration?

armor rods As the tension in the conductor increases, "the tighter the spiral, the greater the gripping force on the conductor." This means that the concentrated load borne by the conductor is converted into a gripping force distribution of armor rods for acsr.

When the conductor undergoes minor displacement or deformation, this shell provides constraint on the conductor through its geometric and material properties, making the conductor and armour rod form a unified whole. Under tension and vibration, this unified structure extends the high-stress area on the conductor to a wider spiral-covered area, suppressing single-point stress peaks.
