New Materials Drive Pre-twisted Wire Durability To New Heights

In recent years, the raw materials for armor rod preformed products have achieved a qualitative leap. Improved alloy composition and composite material technology have been applied to the manufacturing of preformed armour rod. By adjusting metal smoothness, refining grain structure, and increasing tensile strength, the new generation of armor rods has significantly improved in terms of compressive strength, corrosion resistance, and fatigue resistance.

armor rods for acsr, using these new materials, maintains structural stability under long-term stress and environmental changes, is not prone to fracture, and is less susceptible to fatigue cracks. This stability is suitable for high-requirement structural applications such as bridge rigging, building reinforcement, and tower cables. Its durability far exceeds that of traditional armor rods transmission line.

Manufacturers address this issue from multiple aspects, including raw material selection, smelting methods, and surface treatment.

• Optimized alloy composition results in a more uniform metal structure and reduces internal defects.

• Improved surface treatment processes resist corrosive agents such as moisture and salt spray.

• The combination of heat treatment and cold working technologies enhances metal performance and fatigue life.
