OPGW Optical Ground Wire
OPGW (Optical Ground Wire) is a multifunctional cable installed on overhead power lines. It functions both as a grounding wire to shield the power system from lightning and as a conduit for fault currents. At the same time, it houses optical fibers to support high-speed data transmission. Widely deployed in high-voltage transmission networks, OPGW eliminates the need for separate communication lines, reducing installation costs and space usage. Its elevated position and built-in shielding make it resistant to electromagnetic interference, ensuring stable and efficient communication.
