OPGW-OPTICAL GROUND WIRE. OPGW or known as Optical Ground Wire is a type of cable or wire that is used in transmission lines construction. It is also known as optical fiber composite overhead ground wire. It can serve as a grounding wire, shielding wire, and at the same time a cable used for communication purposes.ince 1996 CVG EDELCA has built overhead transmission lines employing optical ground wire cable (OPGW) instead of conventional ground wire, and nowadays, it is replacing conventional ground wire by OPGW cable in about 1366 km of overhead transmission live lines.
