The primary purpose of OPGW (Optical Overhead Ground Wire) is to integrate power transmission and communications. It serves as both a grounding conductor for overhead power lines and a high-speed fiber-optic communication line. Its applications are wide-ranging, including substations, transmission lines, and smart grid construction. It is also used in communications applications such as high-speed wide area networks (WANs), data centers, and submarine cables. Application: Power System Applications: Grounding Protection: Installed atop high-voltage transmission towers, OPGW acts as an overhead ground wire to effectively shield and disperse lightning currents, protecting power lines. Power System Communications: Transmits control, protection, and monitoring signals (such as SCADA signals), as well as audio and video information required by the power system itself.
