OPGW optical cable is a special optical cable that has both power transmission and communication transmission functions. Its unique structure and working principle make it play an important role in the power system. This article will introduce the working principle and structural characteristics of OPGW optical cable in detail.
OPGW optical cable is a charged body, and its working principle in the power system is similar to that of an ordinary ground wire. In the power system, the metal conductor of the OPGW optical cable plays the role of grounding and lightning protection. At the same time, the optical fiber also has the function of transmitting communication signals in the OPGW optical cable.
In the power system, after the metal conductor of the OPGW optical cable is grounded, a loop is formed, in which the power signal is transmitted through the metal conductor, and the communication signal is transmitted through the optical fiber. Since the optical fiber has a high transmission rate and transmission bandwidth, the OPGW optical cable can achieve high-speed and efficient communication transmission.
OPGW optical cable consists of metal conductor, optical fiber and insulation layer, and has the following structural features:
(1) Metal conductor: The metal conductor of OPGW optical cable is made of aluminum-magnesium alloy wire, which has high strength and conductivity, and also has good corrosion resistance, and can operate stably for a long time under harsh environmental conditions.
(2) Optical fiber: The optical fiber of OPGW optical cable is made of high-purity quartz glass material, with high transmission rate and transmission bandwidth, which can meet the needs of power system communication. At the same time, the optical fiber also has high mechanical strength and corrosion resistance, and can operate stably for a long time under harsh environmental conditions.
(3) Insulation layer: The insulation layer of OPGW optical cable is mainly made of epoxy resin and polymer materials, with good insulation performance and electrical breakdown resistance, which can ensure the safe operation of optical fiber under high voltage conditions.
(4) Shielding layer: In order to avoid the interference of power signals on optical fiber transmission, OPGW optical cable is also equipped with a shielding layer to ensure the quality and reliability of communication signals.
The working principle and structural characteristics of OPGW optical cable give it unique application advantages in the power system. At the same time, OPGW optical cable has high transmission rate and transmission bandwidth, good mechanical strength and corrosion resistance, as well as good insulation and electrical breakdown resistance, and can operate stably for a long time under harsh environmental conditions.
With the continuous development and upgrading of the power system, the application field of OPGW optical cable is also expanding, and more and more power companies are beginning to adopt OPGW optical cable to meet the needs of communication and power transmission. In the future, with the continuous advancement and innovation of technology, the application prospects of OPGW optical cable will be broader.
