　　wire， Also known as fiber optic composite overhead ground wire. Fiber optic cables are placed in the ground wires of overhead high-voltage transmission lines to form a fiber optic communication network on the transmission lines. This structural form combines the dual functions of ground wires and communication, and is generally referred to as OPGW optical cables.

　　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 dispatch centers. 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 aluminum clad steel wire or aluminum alloy wire twisted OPGW 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.

　　The basic parameters of OPGW optical cable are as follows:

　　1. Fiber optic cable models and structural forms: divided into aluminum clad steel and aluminum alloy;

　　2. Calculate cross-sectional area: Materials are divided into aluminum or stainless steel tubes, aluminum clad steel, and aluminum alloys;

　　3. Outer single wire type: divided into aluminum clad steel and aluminum alloy;

　　4. Outer single wire diameter;

　　5. Light type;

　　6. Number of fiber cores;

　　7. The average attenuation coefficient of a single fiber in both directions after OPGW cabling is 1550nm;

　　8. Outer diameter;

　　9. Unit length mass (including fiber mass);

　　10. Rated tensile strength (RTS);

　　11. 20 ℃ DC resistance

　　12. Allowable short-circuit current capacity (40 ℃~200 ℃, 0.25s)

　　13. High allowable temperature: divided into instantaneous high allowable temperature and sustained high allowable temperature;

　　14. Lightning resistance energy (50c/100c/150c/200c);

　　15. Tension to weight ratio;

　　16. Elastic modulus;

　　17. Linear expansion coefficient;

　　18. Allow tensile force;

　　19. Annual average operating tension;

　　20. Small allowable bending radius (dynamic);

　　21. Allow installation of tension;

　　22. Axis dimensions (length x width x height).

　　23. Disk length, etc.
