Description :

　　OPGW fiber optic cable manufacturer OPGW power communication fiber optic cable

　　Placing optical fibers in the ground wire of overhead high-voltage transmission lines to form an optical fiber communication network on the transmission lines, this structural form combines the dual functions of ground wire and communication, and is generally referred to as OPGW optical cable.

　　Due to its anti electromagnetic interference and light weight, optical fibers can be installed on the top of transmission line towers without considering issues such as mounting position and electromagnetic corrosion. Therefore, OPGW has significant characteristics such as high reliability, superior mechanical performance, and low cost. This technology is particularly suitable and economical for new installation or replacement of existing grounding wires.

　　Fiber optics utilizes the difference in refractive index between the core and cladding materials to transmit light energy through optical fibers, which has become a major revolution in the history of communication. Fiber optic cables are lightweight and compact, and have been adopted by power systems to transmit dispatch calls, remote signals, relay protection, television images, and other information between substations and central substations. In order to improve the stability and reliability of fiber optic cables, foreign countries have developed a structure that combines fiber optic cables with transmission lines, overhead ground wires, and power cables. OPGW optical cable is more reliable, stable, and sturdy due to the metal wire wrapping. As the overhead ground wire and optical cable are combined into one, it not only shortens the construction period but also saves construction costs compared to using other types of optical cables. In addition, if OPGW made of aluminum clad steel wire or aluminum alloy wire is used, it is equivalent to setting up a good conductor overhead ground wire, which can achieve various benefits such as reducing the potential supply current of transmission lines, reducing power frequency overvoltage, improving the interference and dangerous impact of power lines on communication lines, etc.
