Problems solved by technology

Optical cable operation and maintenance lines are long, and operation and maintenance are more difficult. According to the calculation of 50% coverage of 500kV cross-regional transmission lines and large-span pole tower status monitoring, the lines to be monitored will also be 200,000 kilometers. From the development of line inspection to the popularization of electronic monitoring systems today, although the optical cable status monitoring technology has made great progress, it still faces severe challenges
At present, the optical cable status online monitoring system is mainly composed of various electronic sensors. Therefore, when building the monitoring system, it is necessary to install an additional power supply and lay power pipeline
