In modern transmission and communication networks, reliability and durability are everything. Overhead conductors face constant exposure to wind, vibration, and environmental stress, which can cause wear and fatigue over time. That’s where preformed armor rods—also known as overhead line fittings or preformed line accessories—play a crucial role. These precision-engineered rods protect and reinforce conductors, ensuring long-term stability across power infrastructure worldwide.
But behind every high-quality armor rod lies a piece of advanced machinery. As a leading preformed wire forming machine manufacturer, Xingang Machinery provides efficient, precise, and fully automated solutions for producing armor rods, repair rods, and related transmission line hardware.
What Are Preformed Armor Rods?
Preformed armor rods are helically formed metal rods—typically made from aluminum alloy, galvanized steel, or aluminum clad steel. They wrap around power conductors to protect them from abrasion, fatigue, and vibration. Common types include:
- Vibration protection rods (used to reduce aeolian vibration)
- Anti-corrosion armor rods (for coastal or industrial environments)
- Conductor repair rods (for damaged wire restoration)
- Aluminum clad armor rods and galvanized steel armor rods (for different conductor materials and environments)
These power line hardware components are essential in transmission lines, ADSS cable systems, and OPGW fittings—particularly in regions with strong winds or extreme weather conditions.
Why Manufacturing Quality Matters
Producing preformed armor rods is not just about twisting wires. Each rod must have precise pitch, uniform diameter, and consistent tension, so it fits securely around the conductor without causing stress concentration.
Traditional manual forming can result in inconsistent shape or low efficiency. In contrast, modern preformed line forming machines ensure:
- ±1° forming precision
- Consistent pitch and diameter control
- High-speed production for large-scale orders
- Adaptability for different conductor sizes and materials
