Optical fiber cables are light in weight and small in size, have been adopted by power systems, and transmit information such as dispatch telephones, telecontrol signals, relay protection, television images and the like between a transformer substation and a central dispatching station. In order to improve the stability and reliability of the optical fiber cable, a structure that the optical cable, a phase conductor of a power transmission line, an overhead ground wire and a power cable are compounded into a whole is developed abroad. The OPGW optical cable is wrapped by the metal conducting wire, so that the optical cable is more reliable, stable and firm, and the construction period is shortened and the construction cost is saved compared with the optical cable using other modes because the overhead ground wire and the optical cable are compounded into a whole. In addition, if the OPGW twisted by the aluminum-clad steel wire or the aluminum alloy wire is used, namely a good conductor overhead ground wire is erected, the method can receive the benefits of reducing the secondary current of the transmission line, reducing the power frequency overvoltage, improving the interference and danger influence of the power line on the communication line and the like.
