Intelligent cable

Abstract

The invention discloses an intelligent cable. The middle part of the cable is a cable core intertwisted by a power cable, an optical fiber unit, a communication cable and a coaxial radio frequency cable. A belting layer winds outside the cable core, a total shielding layer is arranged outside the belting layer, and the outermost layer squeezes and wraps an outer protective layer. Double metal shielding layers are respectively arranged for the optical fiber unit, the communication cable and the coaxial radio frequency cable. The double metal shielding layers are separated in the middle by using separating covers. The intelligent cable is formed by combining the optical fiber, the communication cable and the coaxial radio frequency cable in a power cable through a simple and accessible method, various signal cables are physically and completely separated during production, so that the cables do not disturb each other in transmission so as to effectively ensure the quality and safety. Meanwhile, the intelligent cable has the functions of transmitting power, communication signals, and wire video signals and the function of optical fiber communication, shares the network infrastructure and greatly reduces the investment on network construction.

Description

[0001] technical field [0002] The invention belongs to the field of cable manufacturing, and is also the field of cable manufacturing dedicated to the integration of four networks, and particularly relates to a combination of power cables, communication cables, coaxial radio frequency cables and optical fibers for the Internet. Background technique [0003] As we all know, the State Grid Corporation of China has already fully started the construction of the power fiber optic home pilot project and realized the integration of the three networks. According to the needs of the national strategy, it will definitely change the pattern of the integration of the three networks in the near future and move towards the integration of the four networks, that is, the power grid, The integration of radio and television networks, the Internet and telecommunication networks, in fact, as early as the early days of the smart grid, the State Grid once proposed the concept of four-network int...

Problems solved by technology

[0006] In recent years, some cable peers have made many improvements to optical fiber composite cables, such as the Chinese patent "Photoelectric Composite Cable" (publication number 201629183U, publication date November 10, 2010), which is a power cable, optical cable, communication cable and The combination of radio frequency cables, but it is a one-piece structure, with independent sheaths, but the sheath layer is a connector when extruded. Such a structure is difficult to control during production, it is not easy to wire on the coil, and it is difficult to lay. It is also very large, and has high requirements for special equipment and hardware facilities, which actually loses the practical significance of being a combination or composite

Another example is the Chinese patent "Rated Voltage 0.6 / 1kV and Below Optical Fiber Composite Low-Voltage Intelligent Cable" (publication number 201994129U, publication date September 28, 2011), that is, the cable core is composed of a cable insulation core and an optical unit, which only realizes The transmission of electric energy and network signals simply integrates the power grid and the Internet, and is limited to low-voltage cables. It is not considered as a composite cable on the backbone line, and there is still much room for improvement.
