Overhead transmission lines use Optical Ground Wire (OPGW), which combines: Inside substations, overhead fiber cannot be routed directly into buildings. An optical fiber composite overhead ground wire (OPGW) is a new type of ground cable used in the high-voltage power transmission system that serves as both a conventional overhead ground cable and a communication optical cable. An OPGW cable contains a tubular structure with one or more optical. The shield wire constructed with fiber inside it is called the Optical Ground Wire (OPGW). The one shown in the GIF image comes with up to 144 count fiber. From relaying standpoint only 2 fibers are needed (1-TX, 1-RX) for each relay. (2) When the OPGW enters the substation frame, the connection between the OPGW and the grounding grid connection point at the top of the substation frame must be connected with a grounding wire. The joint box is made of aluminium alloy and has a maximum c pacity of 240. This manual is formulated in accordance with IEEE 1138 - 2008 and IEEE 524 - 1992, etc. It is composed of AS wire, AA wire and stainless steel tube optical unit.
