OPGW- Optical Fiber Composite overhead ground wire

Optical fiber composite overhead ground wire (OPGW) is an overhead ground wire containing optical fibers, featuring multiple functions such as overhead ground wire and optical communication. It is mainly used in communication lines of 110kV, 220kV, 500kV, 750kV and newly built overhead high-voltage transmission systems. It can also be used to replace the existing ground wires of the old overhead high-voltage transmission system, add optical communication lines, conduct short-circuit currents and provide lightning protection. Special structures can be customized according to user requirements.

Product standard

•According to IEC-60794-4-10-2014

•Applications：It is used for communication in power system and has dual functions of ground wire and communication

Product features

•Adopt advanced stainless steel tube production technology,the tube is filled with special thixotropic jelly to provide key protection for the optical fiber.

•Good compactness and high tensile strength.

•Precise design of optical cable section to ensure the electrical properties, mechanical and physical properties and thermal stability of the cable .

•fiber surplus length and cable core stranded pitch ensure that OPGW cable will not be stressed at the maximum operating tension.

•Similar to common ground wire specification, it is very convenient to install and replace the original ground wire directly.
