Why Do Pre-stranded Wires Perform Better In Vibration Environments?

Compared to solid conductors, armor rods conductor is composed of multiple filaments twisted in a specific manner. This combination allows armor rod preformed to exhibit greater flexibility and multiple microscopic moving units under external forces. The relative movement between these units can disperse loads and external disturbances, thus enabling the material to exhibit greater mechanical adaptability under vibrational loads.

Under vibrational conditions, the multi-strand structure of preformed armour rod is not a simple static connection, but a system capable of undergoing minute changes under stress. The twisting between the filaments provides a "buffering" environment. When the load changes periodically, this structure prevents localized stress concentration, distributing it along multiple paths and reducing the peak stress experienced by a single filament.
