TECHNOLOGY FOR DESIGNING OVERHEAD COMMUNICATION LINES WITH FIBER OPTIC CABLES

 

Volume of “manual work” for all object Volume of work from column 1 in % being automated Project operations Result Description
    Mechanical calculation of self-supporting fiber optic communication cables Justifying the selected cable, accepted tension (stress) for all conditions (cable strength, load-bearing capacity of constructions, etc.). Specifying reference overall span View
    Mechanical calculation of wires for power transmission line Defining the behavior of wires on the existing overhead power transmission line (sag, stresses) to make decisions on mounting self-supporting communication cables. Co-relation between their sag and stresses View
    Defining the tension in ground wire (optical ground-wire cable) considering the distance between the wire and the cord in the span Justifying the selected optical ground-wire cable, accepting the permissible tension (stress), maximum and at average annual temperature considering the distance between the cord and the wire View
    Calculating crossings between the overhear communication line and engineering objects and natural obstacles Providing the clearances at crossings View
    Calculating mounting stresses and sag of self-supporting fiber optic cable Providing the contractor for mounting works with the tables (curves) for mounting stresses and sag of the cable that are compatible with operating conditions (LineMech, LineCross, etc.) View
    Calculating mounting stresses and sag of wires on the existing power transmission line alongside the new self-supporting fiber-optic cable Providing the contractor for mounting works with the tables (curves) for mounting stresses and sag of the communication cable, a part of the overall calculation for the power transmission line, including the data on the line’s wire and communication cable behavior of the line in mounting modes (regardless of whether the self-supporting cable is used as a ground wire (optical ground-wire cable) or not). This would give the whole picture of sagging both of the line’s wires and the optical cable at different temperatures. It is necessary to check if the sag and stresses in the line’s wires correspond to the measured ones at particular temperatures. View


Other date on the designing technology will be provided by the developers later.
