Lightning protection grounding wire for overhead optical cables

An OPGW (Optical Ground Wire) Cable is a robust solution for integrating fiber optic communication within overhead power transmission lines. This OPGW cable functions as both a ground wire, protecting the line from lightning strikes, and a fiber optic cable, enabling high-speed. Bekaert is the leading manufacturer of static wires in North America. It serves two primary functions: Unlike traditional ground wires, OPGW contains optical fibers embedded within its metallic structure, allowing power utilities to transmit voice. OPGW is primarily used by the electric utility industry, placed in the secure topmost position of the transmission line where it “shields” the all-important conductors from lightning while providing a telecommunications path for internal as well as third party communications. When people ask, “what is OPGW?” they are often curious about how a single cable can serve such a dual.
