Optical Ground Wire Engineering 101

This session will teach you the advantages and disadvantages of the three basic design types of OPGW used today. You will also learn the “best practices” for each type. We will continue with the trade-offs between fiber count, diameter, and fault current capacity. This will then segue into the details of how the required fault current capacity should be determined by a utility along with how it is then computed by a cable manufacturer for a cable design. We will explain why it is not a good idea to require that the capacity be comparable to that of a conventional (that is, non-fiber optic), commonly-used overhead ground wire. We will finish by discussing lightning performance.
