| Abstract: | There are outstanding advantages to transmit information using OPGW(composite fiber optic overhead ground wires )for high voltage transmission lines, having large communication capacity, strong antidisturbance, high reliability on towers and not need additional corridors, etc. But for being covered with leaden sheath, aluminum- alloy and aluminum - clad wires, its impedance by far less than that of zinc -coated steel wires and the grounding resistance of towers, the OPGW will carry large current when one lhase to ground short - circuit happens, causing sgarp rise of temperature of OPGW and the detreioration of its performance. This article is to work out the different measures to lower the short - circuit through OPGW. |
