Overhead Line LS Cable & System overhead wire is composed of ACSR and overhead ground wire. They are normally installed on steel towers, and recently the usage of high-capacity conductors for high-capacity transmission among power cables is increasing. Among overhead earth wires, the usage of OPGW, which has included communication functions to optical
OPGW (Optical Ground Wire)
Optical ground wire, or OPGW, includes communication functions provided by the incorporated optical fibers in addition to the existing overhead ground wire which protects the transmission cables from lightning strikes and secures current flow in case of cable faults.
