: Pre-twisted optical cable hardware
< The main hardware required for optical cable installation: tension clamps, down conductors Clamps, special ground wires, anti-vibration hammers, protective strips, optical cable connector boxes and residual cable racks, etc. All optical cable fittings supporting the optical cable in this project are supporting products of the optical cable supplier.
There are two types of hardware strings in this project: pendant and tension-resistant ones. All tension towers are equipped with tension-resistant hardware, and the rest of the linear towers are equipped with pendant hardware.
The strength of a single suspension clamp is not less than that of a single suspension clamp, and the overall strength of a double suspension clamp is not less than that of a single suspension clamp. The gripping force %R of the suspension wire clamp pair, and the allowable value of the suspension angle at the outlet of the suspension wire clamp shall not be less than.
The holding force of the tension clamp shall reach % of the breaking force, and shall not slip or be damaged. The steel pipe containing the optical fiber shall not be deformed in any way. The damage strength of the tensile fittings is not less than () (the strength of the tensile fittings used on the frame side is not less than).
The actual safety factor of the design of optical cable fittings is: operating conditions >., disconnection and disconnection conditions >., meeting the relevant regulations in the design regulations.
