500 KV OPGW WORK

OPGW (Optical Ground Wire) work at the 500 kV level involves installing a dual-function cable—serving both as a grounding conductor and as a fiber-optic communication link—along transmission tower spans. Activities include drum unwinding, tensioning, stringing, sag adjustment, mid-span jointing, dead-end clamping, and optical connectivity testing. Installation adheres to IEC standards and NTDC/WAPDA protocols to ensure mechanical integrity, lightning protection, and secure real-time data transmission across the grid.
