While sharing core tensioning and pulling principles, an "OPGW Stringing Machine" is engineered with crucial specializations due to the delicate fiber optic core within the OPGW cable:

• Ultra-Precise Tension Control: OPGW has a much lower permissible tension limit than traditional conductors before its optical fibers can be damaged. Our OPGW machines feature highly sensitive hydraulic or electronic control systems for constant, low-tension stringing.

• Specialized Sheaves/Grooves: Tension wheels and OHTLstringingequipment.com/Stringing-Blocks--Sheaves.html target='_blank'>Stringing Blocks (sheaves) on OPGW machines have larger diameters and often feature non-metallic, extra-smooth, or specially lined grooves (e.g., polyurethane, nylon) to prevent crushing, kinking, or abrasion of the cable's outer strands, which could damage the optical fibers.

• Integrated Anti-Twist Mechanisms: Many OPGW machines and accessories incorporate sophisticated anti-twist devices and Swivels designed to prevent torsional stress on the cable, which is critical for optical fiber integrity.

• Advanced Dynamometers: Equipped with highly accurate digital dynamometers that provide real-time tension feedback and often have automatic shutdown features to prevent over-tensioning.

This specialization is crucial because any damage to the OPGW's outer layers or induced stress on the fibers can lead to signal loss, increased attenuation, and ultimately, system failure.
