With the continuous development and upgrading of power systems, more and more power companies and institutions have begun to pay attention to and use OPGW optical cables. So, why are OPGW optical cables becoming more and more popular in power systems? This article GL FIBER will analyze its advantages and applications to answer this question.
1. Advantages of OPGW optical cable
Excellent overall performance
OPGW optical cable has both the communication transmission function of optical cable and the power transmission function of metal optical cable, combining the advantages of both transmission methods. Optical cables can transmit large amounts of data, while metal optical cables can transmit high-voltage and high-current power signals. Therefore, OPGW optical cables are superior to other transmission methods in terms of overall performance.
Safe and reliable
Since the OPGW optical cable is hung on the power transmission line, its laying will not affect the laying of ground transportation and buildings. At the same time, optical cables and metal optical cables are independent of each other. Even if the optical cable fails, it will not affect the normal operation of the metal optical cable. Therefore, OPGW optical cable has high safety and reliability.
Save space
Compared with traditional optical cables and electric cables, OPGW optical cables do not need to be laid separately and can be laid together with power transmission lines, saving space resources.
Economical and practical
Although the cost of OPGW optical cable is relatively high, it can transmit communication and power signals at the same time, saving the cost of other transmission methods, so it is economical and practical in long-term use.
2. Application of OPGW optical cable
OPGW optical cables are widely used in power systems, including the following aspects:
Power communications
OPGW optical cable can transmit a large amount of communication data, realize remote monitoring and communication of the power system, and improve the safety and reliability of the power system.
Lightning protection
OPGW optical cable has good lightning protection capabilities, which can reduce lightning strike losses and power outage time of the power system, and improve the stability and reliability of the power system.
line monitoring
OPGW optical cable can be used for line monitoring of power systems. It can monitor the voltage, current, temperature and other parameters of the power system in real time, improving the operating efficiency and safety of the power system.
Optical fiber temperature measurement
The optical fiber in the OPGW optical cable can be used to measure the temperature of the power system, which can help the power company detect line faults in time.
