Maximum wind speed for overhead optical cables
Wind speed (up to 320km/h) Example: A 288-fiber ADSS cable on 50m poles requires 7/2. Tensioning: Set messenger wire tension to 15–20% of breaking strength to allow thermal expansion. Clearance requirements for aerial cables are defined in Section 23 of the National Electrical Safety Code® (NESC®). Understanding Overhead Fiber Optic Cable Overhead fiber optic cable are designed to be suspended from utility poles or dedicated structures, leveraging existing aerial infrastructure to minimize construction costs. For issue to all Ausgrid and Accredited Service Providers' staff involved with the design of overhead lines, and is for reference by field, technical and engineering staff. Where this Standard is issued as a controlled document replacing an earlier edition, remove and destroy the superseded. If the cable remains outside for more than 24h during installation protective material should be used to prevent cable damage.
