Application and advantages of OPGW optical cable in power system

With the continuous advancement of science and technology, the application of optical cable in power system is becoming more and more extensive. Among them, OPGW optical cable has become an important choice in the field of power communication with its unique advantages. This article will introduce the application and advantages of OPGW optical cable in power system in detail.

1. Introduction to OPGW optical cable

OPGW optical cable, that is, optical fiber composite overhead ground wire optical cable, is an optical cable that composites optical fiber units in overhead ground wires. It has both the lightning protection and grounding protection functions of ground wires and the communication function of optical fibers. Therefore, OPGW optical cable has been widely used in power communication systems.

2. Application of OPGW optical cable in power system

a. Communication transmission: 

OPGW optical cable, as a component of power lines, can easily realize the communication transmission of power lines. The communication network built with OPGW optical cable can meet various communication needs in power systems, such as dispatching control, automatic meter reading, video monitoring, etc.

b. Smart grid construction: 

Smart grid is the development direction of future power systems, and OPGW optical cable plays an important role in the construction of smart grids. Through OPGW optical cable, real-time monitoring, control and dispatching of the power grid can be realized, and the operation efficiency and safety of the power grid can be improved.

c. Lightning protection: 

As part of the ground wire, OPGW optical cable has a good lightning protection function. When lightning strikes the power line, OPGW optical cable can effectively introduce current into the ground to protect the safety of communication equipment and personnel.

3. Advantages of OPGW optical cable

1. High reliability: As part of the ground wire, OPGW optical cable has been subjected to the action of electricity for a long time, so it has high reliability. In addition, due to its special structure and material, OPGW optical cable has strong tensile, compressive and bending resistance, and can adapt to various complex environmental conditions.

2. Easy maintenance: Since OPGW optical cable is installed together with power lines, OPGW optical cable can be inspected and maintained at the same time when maintaining the power line, without the need to arrange time and manpower separately.
