However, the usage of such cables during a transient request may lead to an unusual distribution of current along the grounding electrodes. Thus, it is interesting observe if these cables would case decreased or increased of safety on the vicinity of substation. costco business adNettetUtilities quickly adopted OPGW for their communications needs and grid management. It’s unlikely that any new transmission lines would be built today without OPGW. Cable manufacturers now also offer power conductors with fibers inside, so if a tower is getting new power lines, it could also be an option to install more fiber. breakdown\\u0027s 3f
