Main features of OPGW optical cable
1. Using advanced stainless steel tube production technology, the tube is filled with water-blocking compounds to effectively protect the optical fiber;
2. By optimizing the length of the fiber in the stainless steel tube and the stranding pitch of the core, the second excess length of the fiber in the cable is obtained to ensure that the cable is not affected by the maximum working tension.
3. The compact structure can not only reduce the ice load and wind load, but also ensure that the heat generated by the short circuit is easily dissipated.
4. The outer diameter and pull ratio of OPGW optical cable are similar to ordinary grounding wires, which can directly replace the original grounding wires without changing lines or towers.
5. Since it is basically consistent with traditional overhead ground wires, OPGW optical cables are very easy to install.
With the development of the times, the advancement of science and technology, and the rapid development of the information industry, the performance of industrial products needs to be further improved. In modern industrial enterprises, higher requirements are placed on automation, safety, reliability of data and transmission. In the power grid, the composite optical cable OPGW is used as a lightning arrester for transmission lines as an example. The advantages are as follows:
(1) The composite optical cable OPGW maintains the original characteristics of the lightning arrester, protects the transmission line from lightning strikes, and shields the transmission line when a short circuit occurs, minimizing the interference of the short circuit current to the power grid, communications, railways and pipelines;
(2) The composite optical cable OPGW is used for data signal transmission. It can transmit audio, video, data and various control signals through terrestrial optical fiber, as well as multi-channel broadband communication, as a medium for transmitting optical signals.
(3) The composite optical cable does not require a single tower, does not occupy channels, saves investment, and improves the utilization efficiency of the production line.
Composite optical cable OPGW is a new product widely popularized in China in recent years. High technical content, strict construction requirements. Its main material is fiber. Optical fiber is not only an optical medium waveguide, but also an information transmission medium with good insulation properties. It has the characteristics of corrosion resistance and high temperature resistance. It is characterized by large capacity, no attenuation of long-distance transmission signals, no noise and electromagnetic interference, light weight, and small diameter. The disadvantage of optical fiber composite overhead ground wire is that the construction process is complicated and difficult, and the optical cable is not easy to break, curl, bend and stretch. If the fiber optic composite overhead ground wire frays and breaks, the entire fiber optic cable will be scrapped. Therefore, it is strictly protected according to the technical regulations.
