OPGW hardware in the USA includes dead ends, suspensions, vibration dampers, and stringing tools designed to support OS2 fiber optic cables in overhead power lines.

Key Hardware Components

Dead Ends: Full-tension terminations, such as wedge dead ends, secure OPGW cables at tower anchor points. These devices are often pre-assembled and require minimal installation steps, improving efficiency and reducing labor time (AFL) . Suspensions: Hinged Bushing Suspensions (HIBUS) and mechanical suspensions support OPGW spans while reducing static and dynamic stress. They accommodate vertical, transverse, and longitudinal loads without damaging the cable or affecting fiber performance . Vibration Dampers: Spiral vibration dampers (SVD Series) mitigate aeolian vibration, which can damage both the cable and the optical fibers. These are essential for long spans exposed to wind-induced oscillations . Stringing Tools: OPGW comealongs and other pulling devices are used to tension and position the cable during installation. Lightweight mechanical supports allow for safe handling and angle changes without compromising the cable integrity .

Selection Considerations

When selecting hardware for OS2 fiber OPGW, it is important to gather the following cable information:

• Cable Diameter: Overall outer diameter of the OPGW cable.
• Strand Configuration: Lay direction, number of layers, and material distribution.
• System Requirements: Tensile strength, vibration tolerance, and galloping resistance according to IEEE 1138 standards . Hardware must be compatible with the specific OS2 fiber cable construction to ensure long-term reliability and compliance with industry standards .

Additional Notes

• Multi-layer strand cables may require specialized hardware after technical review.
• Many manufacturers, such as AFL and PLP, provide pre-tested hardware solutions for US transmission and distribution networks .
• Proper installation and testing are critical to maintain optical performance and mechanical integrity of OS2 fibers in OPGW systems. By using the appropriate dead ends, suspensions, vibration dampers, and stringing tools, utilities can ensure reliable, long-term performance of OS2 fiber in OPGW installations across the USA.
