What are "OPGW protection rods" and "armor rods," and why are they essential accessories for OPGW longevity?
2025-07-21"OPGW protection rods" and "armor rods" are crucial "OPGW Stringing Accessories" designed to safeguard the cable from mechanical stress and damage at points of attachment:
-
Protection Rods: These helical rods are applied over the OPGW at suspension points (like OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks or suspension clamps). They increase the bending radius and distribute clamping forces over a longer area, preventing concentrated stress, abrasion, and fatigue that could damage the outer strands and ultimately the optical fibers.
-
Armor Rods: Used similarly, often pre-formed and applied at dead-end or tension points. They provide superior protection against abrasion and fatigue from vibration and tension, ensuring the OPGW maintains its structural and optical integrity under constant load.
Both are vital for extending the service life of the OPGW, especially in areas prone to wind-induced vibration or high tension.
