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.
The disadvantage to SMAW is that the slag must be chipped off of the weld after it cools, and can sometimes infiltrate the weld causing weakness. GMAW. GMAW stands for gas metal arc welding. This is also commonly referred to as metal inert gas welding, or MIG welding. In GMAW the electrode is a roll of wire which the welder feeds out of a âgunâ to the work piece. You control the speed of the wire, so you can make long welds without stopping to replace a rod.
