Product Details
OPGW optical cable, Optical Fiber Composite Overhead Ground Wire
Placing optical fibers in the ground wire of overhead high-voltage transmission lines to form the optical fiber communication network on the transmission line, this structure
The form has both ground wire and communication Dwifungsi, and is generally called OPGW optical cable.
Due to the characteristics of electromagnetic interference resistance and light weight of optical fibers, they can be installed on the top of transmission line towers without considering the need for installation
Issues such as hanging position and electromagnetic corrosion. Therefore, OPGW has high reliability, superior mechanical performance, and low cost
Significant features. This technology is particularly suitable and economical when laying new or replacing existing ground wires.
Optical fiber makes use of the difference in the refractive index between the core and cladding materials to enable light to be transmitted in Optical fiber, which is in the history of communication
Becoming a major revolution. Fiber optic cables are lightweight and small in size, and have been adopted by power systems in substations and central dispatch centers
Inter transmission of dispatching telephone, telecontrol signals, relay protection, television images and other information. To improve the stability and reliability of fiber optic cables
Foreign countries have developed a structure that combines optical cables with phase conductors of transmission lines, overhead ground wires, and power cables. OPGW light
The cable is wrapped in metal wires, making it more reliable, stable, and sturdy. Due to the combination of overhead ground wire and optical cable
Compared to using other methods of optical cable, it not only shortens the construction period but also saves construction costs. Additionally, if aluminum clad steel wire or aluminum alloy is used
The OPGW made of twisted gold wire is equivalent to erecting a good conductor overhead ground wire, which can reduce the potential supply current of the transmission line and reduce the
The benefits of power frequency overvoltage, improving the interference and dangerous effects of power lines on communication lines, and other aspects.
