This article briefly talks about the composite optical cable OPGW, hoping to help you increase some knowledge in the field of optical cables.
With the development of the times and the rapid growth of the information industry, the performance of industrial products is required to be further improved. In modern industrial enterprises, higher requirements are put forward for automation safety, reliable data and transmission. The use of composite optical cable OPGW in the transmission line lightning protection line in the power grid is an example. Its advantages are:
(1) Composite optical cable OPGW maintains the original characteristics of the lightning protection line, provides protection for the lightning resistance of the transmission line, and acts as a shield when the transmission line is short-circuited, thereby reducing the interference of the short-circuit current to the power grid, communications, railways, and pipelines;
(2) Composite optical cable OPGW is used for data signal transmission, through the optical fiber composited in the ground wire as the medium for transmitting optical signals, it can transmit audio, video, data and various control signals, and perform multi-channel broadband communication;
(3) Composite optical cable does not need a separate pole tower, does not occupy the channel, saves investment, and improves the utilization efficiency of the line.
Composite optical cable OPGW is a new product that has been widely promoted in recent years. It has relatively high technological content and has strict requirements for construction. Its main material is optical fiber.
Optical fiber is a kind of optical dielectric waveguide and a kind of information transmission medium with good insulation performance. It has various properties such as corrosion resistance and high temperature resistance. It is free from noise and electromagnetic interference, and has the advantages of light weight and small diameter.
The disadvantage is that the construction process is complicated and difficult, and the optical cable is not easy to be folded, pressed, bent and stretched. If the OPGW is worn or broken, the entire optical cable will be scrapped. Therefore, during construction, it is necessary to strictly follow the technical regulations and strictly protect them.
The above is the knowledge about composite optical cable OPGW, I hope it will be helpful to you.
