OPGW / Photoelectric Composite
Optical Fiber Ground Wires (OPGW) refers to cables installed on pylons along with transmission lines, and are equipped with various functions including playing a role of overhead ground wires protecting high voltage transmission lines and providing optical fiber communication lines. OPGW reinforced with aluminum-clad steel wire strands not only satisfy the mechanical and electrical properties of ordinary overhead ground wires, but their inner optical fiber is also able to maintain stable performance even when extreme changes occur in the external environment, such as typhoons, lightning strikes, and power line accidents.
