Purpose of the self-proclaimed steel wire of the figure-8 optical cable

The self-proclaimed steel wire (i.e. suspension wire) of the figure-8 optical cable is mainly used to bear the tension of the optical cable to ensure that it can be stably suspended in an overhead environment. This steel wire is usually phosphated or galvanized to enhance its anti-rust performance, and is fixed to the pole tower with a special hook or tie band. ‌
Specific use ‌Mechanical support‌: The high-strength steel wire bears the weight of the optical cable itself and the external tension, and is suitable for long-span overhead laying of 50-100 meters. ‌
‌Rust-proof treatment‌: Surface phosphating or galvanizing can extend the service life and reduce maintenance requirements. ‌
‌Installation method‌: It is fixed to the pole tower with a special hook or tie band to ensure that the optical cable does not slide or swing. ‌
Construction precautions ‌Span control‌: The maximum span is recommended not to exceed 80 meters, and it needs to be shortened to within 50 meters in windy areas. ‌
‌Fixation method‌: Special accessories (such as hooks or tie bands) are required to ensure firmness. ‌
‌Bending radius‌: The bending radius during installation should be ≥20 times the diameter of the optical cable to prevent damage to the optical fiber.
