The main difference between Optical Ground Wire (OPGW) and traditional static/shield/earth wires is that OPGW is a dual-functioning cable that serves both as a ground wire and a communication network. Traditional static/shield/earth wires, on the other hand, are used solely for grounding purposes.
OPGW cables are designed to replace traditional static/shield/earth wires on overhead transmission lines, and they are capable of withstanding the mechanical stresses applied to overhead cables by wind, ice, and other environmental factors.
OPGW cables are also capable of handling electrical faults on the transmission line by providing a path. Traditional static/shield/earth wires, however, do not have the capability to provide a communication network.
OPGW cables contain a tubular structure with one or more optical fibers in it, surrounded by layers of steel and aluminum wire, while traditional static/shield/earth wires are typically made of steel or aluminum.
In summary, the main difference between OPGW and traditional static/shield/earth wires is that OPGW serves a dual function as a ground wire and a communication network, while traditional static/shield/earth wires are used solely for grounding purposes.
