Galvanized steel strands are used to enhance tensile strength and structural support, and are often used as reinforcing cores or armor layers. Their high-strength stranded steel wires can withstand the huge tensile force when cables are suspended or laid, and are suitable for overhead lines, underwater cables, and large-span scenarios; the galvanized layer provides corrosion protection and is suitable for harsh environments such as moisture and salt spray. In addition, steel strands can also help fix the cable shape, and in some designs they also serve as grounding conductors. Compared with steel strips, they are lighter and more flexible, and are suitable for dynamic bending or frequent movement.
