Optical Ground Wire (OPGW) is a dual functioning cable. It is designed to replace traditional static / shield / earth wires on overhead transmission lines with the added benefit of containing optical fibers which can be used for telecommunications purposes. It is best suited to applications with moderate to low span ut increasing fibre strain. Because of this, OPGW contains exposed elements made of both. Optical fiber composite overhead ground wire (OPGW) 1. An OPGW cable contains a tubular structure with. CentraCore optical cable houses and protects the optical fibers within a central gel-filled stainless steel tube inside an aluminum pipe. Installed at the top of high-voltage and extra-high-voltage transmission lines, OPGW cables provide lightning. Tratos OPGW Cables (Optical Ground Wire) combine electrical grounding, lightning protection, and high-speed data transmission into a single cable designed for use in overhead power line infrastructures.
