OPGW Photoelectric Composite Optic Cable
The optical fiber is laid on the ground wire of the overhead high-voltage transmission line, and the optical fiber communication network is formed on the transmission line. This structure has the dual function of ground wire and communication, and is generally called OPGW fiber optic cable.
Optical fibers are resistant to electromagnetic interference and light weight, and can be installed on top of transmission line towers without considering the optimal installation location and electromagnetic corrosion. So, OPGW has the characteristics of high reliability, superior mechanical properties, and low cost. This technology is particularly useful and economical when laying or replacing existing ground wires.
Features of OPGW Optical Cable
- 110KV and above high-voltage lines. Large span (generally greater than 250M).
- It is easy to maintain, easy to solve the problem of crossover lines, and its mechanical properties can meet the needs of large-span lines.
- OPGW optic cable adopts metal armor, which has no effect on high pressure corrosion and aging.
- OPGW optic cable must be powered off during the construction process, and the power loss is large. OPGW should be used for new high-voltage lines above 110KV.
- In the performance index of OPGW, the larger the short-circuit current is, the more good conductors need to be used as armor, and the tensile strength is also reduced. In the case of a certain tensile strength, the short-circuit current capacity should be increased. Simply increasing the metal cross-sectional area results in an increase in cable diameter and cable weight, creating safety concerns for pylon strength.
