DAZHENG wire and cable OPGW-24 core -50 fiber composite ground wire with excellent quality

OPGW optical fiber composite over head ground wire

Closed overhead ground wire)

Place the optical fiber in the ground wire of the overhead high-voltage transmission line to form the optical fiber communication network on the transmission line,

This type of structure 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 the need for suspension

Location and electromagnetic corrosion issues. Therefore, OPGW has significant advantages such as high reliability, superior mechanical performance, and low cost

Characteristics. 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 the power system between substations and central dispatch centers

Transmit dispatching telephone, telecontrol signals, relay protection, television images, and other information. In order 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 optical cable due to

Wrapped with metal wires, the optical cable is more reliable, stable, and sturdy. Due to the combination of overhead ground wire and optical cable, it is different from using other materials

Compared to the optical cable method, it not only shortens the construction period but also saves construction costs. In addition, if aluminum clad steel wire or aluminum alloy wire is used for stranding

OPGW is equivalent to erecting a good conductor overhead ground wire, which can reduce the potential supply current of transmission lines, reduce power frequency overvoltage

Improving the interference and hazardous effects of power lines on communication lines, among other benefits.
