OPGW (Optical Fiber Composite Overhead Ground Wire) is a innovative cable that integrates optical fiber communication into power transmission lines. It consists of optical fiber units and metal conductors, serving both as a ground wire and a communication medium. Primarily used in high-voltage power system overhead lines, OPGW is essential for smart grid development and advanced technologies, ensuring extensive future application in power systems.
● Good tensile strength
● Small diameter, light weight, small additional load on the tower
● Easy to make appropriate fiber excess length optical unit
