Dazheng wire and cable OPGW-24 core -60 fiber composite ground wire with strong tensile resistance

OPGW optical cable, Optical Fiber Composite Overhead Ground WireGround wire)

Place optical fibers in the ground wire of overhead high-voltage transmission lines to form the optical fiber communication network on the transmission lineThis kind of knot

The structure has dual functions of ground wire and communication, 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 installationHanging position and

Electromagnetic corrosion and other issues. Therefore, OPGW has high reliability, superior mechanical performance, and low costSignificant features. This technique

The technique 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 communicationBecoming Once

A major revolution. Fiber optic cables are lightweight and small in size, and have been adopted by power systems in substations and central dispatch centersInter transmission dispatching telephone

Remote control signals, relay protection, television images, and other information. To improve the stability and reliability of fiber optic cablesForeign countries have developed optical cables and power transmission

A structure composed of phase conductors, overhead ground wires, and power cables. OPGW lightThe cable is wrapped in metal wires, making it more flexible

Reliable, stable, and sturdy, due to the combination of overhead ground wire and optical cableCompared to using other methods of optical cable, it not only shortens the construction period but also

Save construction costs. Additionally, if aluminum clad steel wire or aluminum alloy is usedOPGW twisted with gold wire is equivalent to erecting a good conductor overhead ground wire

It can reduce the potential supply current of transmission lines and reduceVarious aspects such as power frequency overvoltage, improvement of power line interference and hazardous effects on communication lines, etc

Benefits.
