Product Overview
Preformed Armor Rods (FYH, FAR, and PLG Series Preformed Line Guards) are essential protective hardware used on high-voltage overhead transmission lines, distribution networks, and OPGW/ADSS fiber optic installations. Manufactured by YiHao Power, these helical rod sets are wrapped over conductors at suspension clamps and dead-ends. They reinforce the cable, absorb bending fatigue caused by wind vibration, and protect conductors against clamping damage and electric arc flashovers.

Key Performance Features
- Vibration Fatigue Protection: Distributes bending stress evenly over a wide contact area, preventing strand fatigue failure caused by Aeolian vibration.
- Grit-Coated Grip Security: Selected models feature embedded non-slip grit on the inner surface to maintain high holding force without pinching conductors.
- Atmospheric Corrosion Resistance: Premium aluminum alloy and aluminum-clad steel materials ensure exceptional weatherability in coastal and industrial areas.
Quality Assurance
Every batch of preformed armor rods manufactured by YiHao Power undergoes strict quality control, including tensile grip strength verification, wire pitch tolerance inspection, and corrosion resistance testing.
