There are four main methods of erection of steel Transmission Line Data: T/L shall be submitted for each line. The data shall be submitted at the end of final construction and it shall include the following for each line individually: 1. Power conductor type, size and details of strand 2. Bundle details (i.e. number of conductors per phase) 3. Bundle spacing in inches 4. Typical structure configurations 5. Spacing coordinate X, Y for each phase conductor (X=0, Y=0 shall be center line of structure at ground surface) 6. Sag for phase a, b & c (average, minimum and maximum). 7. Shieldwire type, size and details 8. Spacing coordinate X, Y for each ground wire (for both OPGW & OGW) 9. Sag for each shieldwire (average, minimum and maximum) 10. For each power conductor: AC resistance in /mile, DC resistance in /mile, Reactance in /mile, outside diameter in inches, GMR in inches 11. For each shieldwire: AC resistance in /mile, DC resistance in /mile, Reactance in /mile, outside diameter in inches, GMR in inches 12. For each shieldwire: AC resistance in /mile, DC resistance in /mile, Reactance in /mile, outside diameter in inches, GMR in inches 13. Sag table for each span 14. Plan and profile drawings for each line 15. Parallel running line information in sketch form with name, kV and length marked for each parallel line. 16. Transposition details, phasing and length in sketch from end to end. 17. Total Line length from Bus-bar to Bus-bar at two ends (i.e. Gantry to Gantry + Gantry to GIS or CB). 18. If more than two conductors per phase (for 380kV line) alpha angle N. All the test results shall be tabulated together with the designed (calculated values) for comparison and submitted to COMPANY with other as-built documents towers which a re described
