An "OPGW Installation Machine" refers to the specialized power equipment, primarily a hydraulic puller-OHTLstringingequipment.com/Hydraulic-Conductor-Tensioners.html target='_blank'>Tensioner, designed specifically for the safe and precise stringing of Optical Ground Wire (OPGW). While standard OHTLstringingequipment.com/Conductor-Stringing-Equipment.html target='_blank'>conductor stringing machines focus on pulling and tensioning metallic conductors, OPGW installation machines incorporate critical differences due to the delicate fiber optic core within the OPGW:

• Ultra-Precise Tension Control: OPGW has a much lower permissible tension limit compared to traditional conductors. Our machines feature advanced closed-loop hydraulic systems and electronic controls that maintain a constant, pre-set low tension, preventing fiber damage.

• Large Diameter, Lined Bullwheels: The bullwheels on OPGW machines have significantly larger diameters and are often lined with non-abrasive, high-friction materials (e.g., specific polyurethane, high-density nylon) to minimize the bending radius and prevent crushing or surface abrasion of the OPGW's outer strands.

• Integrated Anti-Twist Mechanisms: Designed to work seamlessly with anti-twist Swivels and devices to prevent torsional stress on the OPGW, which is critical for maintaining optical fiber integrity.

• Advanced Monitoring Systems: Equipped with highly accurate digital dynamometers that provide real-time tension feedback and often feature automatic shutdown if safe limits are exceeded.

These specialized features are crucial for preserving the optical performance and ensuring the long-term reliability of OPGW.
