The primary advantage of OPGW is its dual functionality, which offers significant benefits over a conventional ground wire. By integrating fiber optics into the ground wire, OPGW provides a cost-effective solution for power utilities to establish a reliable communication network without the need for separate infrastructure. It enhances system reliability by enabling real-time monitoring, fault detection, and smart grid applications. This also improves efficiency by allowing for remote control and data transmission, and the robust construction ensures long-term durability against environmental stresses like wind, ice, and electrical faults.
