Photoelectric composite cable

Abstract

The invention relates to a photoelectric composite cable which comprises a composite cable core. The composite cable core is composed of an optical cable core, a wire core and a protective sleeve, thecable core is arranged outside the optical cable core, and the protective sleeve is arranged outside the wire core; an insulating layer is arranged outside the composite cable core, a flame retardantlayer is arranged outside the insulating layer, a waterproof layer is arranged outside the flame retardant layer, an elastic rubber layer is arranged outside the waterproof layer, a shielding layer is arranged outside the elastic rubber layer, a braided net layer is arranged outside the shielding layer, and an insulated sheath is arranged outside the braided net layer; and the insulated sheath composed of an insulated silica gel layer, an anti-aging rubber layer and a polytetrafluoroethylene layer arranged successively from inside to outside. The photoelectric composite cable has high shielding, waterproof, flame-retardant and anti-aging performance, a fiber beam is combined with a cable beam, both electric energy and signals can be transmitted, and the cable has diversified functions, and is more economic and practical.

[0002] Photoelectric composite cable is suitable for broadband access network system as a transmission line. It is a new type of access method. It integrates optical fiber and power transmission copper wire, and can solve the problems of broadband access, equipment power consumption, and signal transmission. China Internet It has formed a scale, and the Internet application is becoming diversified. The Internet is changing people's study, work and lifestyle more and more profoundly, promoting the rapid development of the information industry, and even affecting the entire social process. The application and technological innovation of optical fiber and cable are also It has been paid more and more attention by the industry, and has made outstanding contributions to power transmission in industry and agriculture. Similarly, the emergence of optical cables has greatly promoted the development of the communication industry. With the advent of the 5G era, the application of optical cables has been unprecedented. Development, and with the development of industry and the progress of agriculture, more and more large-scale, long-length power cables are used in industry and agriculture. Because the installation environments of cables vary widely, there are few installation sites that meet the regulations. Therefore, in It is particularly important to ensure the normal transmission and use of power and communication under the condition of high external force. Large-scale and long-length photoelectric composite cables are laid in environments with height differences such as cliffs and hillsides. The cables are often damaged by the weight of the cables. Damaged or even broken, especially in rainy and freezing weather, the communication transmission is interrupted due to its own weight and icing, causing irreparable losses. The existing photoelectric composite cables have poor compressive and tensile properties, and construction and maintenance in some harsh environments It is easy to break, causing the interruption of communication. At the same time, it is necessary to lay new cables again, resulting in the loss of economic property, time-consuming and labor-intensive, and cannot meet the current communication needs.
