OPGW光电复合光缆
光纤敷设在架空高压输电线路的地线上, 在传输线上形成光纤通信网络. This structure has the dual function of ground wire and communication, and is generally called OPGW 光纤电缆.
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. 所以, OPGW has the characteristics of high reliability, 优越的机械性能, 且成本低. This technology is particularly useful and economical when laying or replacing existing ground wires.
OPGW光缆的特点
- 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, 其力学性能可满足大跨度线路的需要.
- 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. 新建110KV以上高压线路应采用OPGW.
- In the performance index of OPGW, 短路电流越大, the more good conductors need to be used as armor, and the tensile strength is also reduced. 在一定拉伸强度的情况下, 应增加短路电流容量. 简单地增加金属横截面积会导致电缆直径和电缆重量的增加, creating safety concerns for pylon strength.
