Talking about the four norms and standards in the construction of six types of wiring
With the development of information technology, people need to use information transmission in both work and life. This year, people's demand for information transmission rate and capacity is getting higher and higher, and the development direction of science and technology will also follow the direction of people's needs. develop. Just like the most prosperous Category 6 wiring system today, it can not only meet the needs of today's people, but also lay the groundwork for future development; because its specifications and standards will lay the foundation for the development of integrated wiring in the later stage. What are the specifications and standards for the six types of wiring?
First of all, before construction, you must carefully consult other professional construction drawings, especially civil structure construction drawings, water, electricity, and ventilation construction drawings. Because the length of the horizontal routing will have a certain impact on the level of the system, and the construction drawings of civil engineering, water, electricity, and ventilation construction drawings have the greatest impact on the direction of the pipeline routing of the horizontal routing subsystem.
Secondly, when reviewing the drawings, use the scale to measure carefully on the drawings to find the most reasonable routing direction for the horizontal wiring subsystem, which not only saves the length of the horizontal cables, but also avoids conflicts with other professional pipelines. The pipeline will inevitably overlap with other professional pipelines. The horizontal pipeline of the horizontal wiring subsystem accounts for the largest proportion in the integrated wiring system. Big inconvenience and contradictions have brought problems such as superelevation of the ground to the civil engineering profession.
In addition, before the pipelines of the horizontal wiring subsystem are pre-buried, the joint review of the drawings should be carefully done, and the technical disclosure should be made to the construction, so as to avoid overlapping with other professional pipelines and cause conflicts. AutoCAD can be used to draw a three-dimensional large sample drawing, and the direction and elevation of other professional pipelines, as well as the specifications and models of various pipelines, can be marked on the large sample drawing, and the optimal construction plan for laying pipelines can be formulated to meet the shortest pipeline route. Requirements for ease of installation.
ZR Cable six types of wiring
At present, there are three methods of horizontal wiring: the method of concealing the steel pipe, the wiring trough in the ceiling, the method of connecting the steel pipe between the trough and the information point, and the method of concealing the ground wire trough. building. The information points in the building are dense and the large bays need to be partitioned. It is characterized by relatively large investment, high process requirements, and difficult construction.
Generally, professional companies are responsible for the installation and commissioning of integrated wiring. The construction party only pre-embeds pipelines and lays cables. If we perfunctory during construction and do not follow the principle of "the shortest pipeline route", the horizontal wiring subsystem pipelines will be added. The length is not conducive to improving the communication capability of the integrated wiring system, the stability of the communication system, and the improvement of the communication transmission rate.
In addition, design allowances should be met during construction. Because in the actual construction, it is impossible to keep the horizontal cables in a straight line all the time, so in the actual installation, the required cables will always be much larger than the amount counted on the drawings, which requires a certain margin to be considered. The calculation method of the margin is to add the cable drawing length of the information point farthest from the patch panel on a plane drawing (the length measured by the scale on the drawing) and the cable drawing length of the nearest information point, Divide by 2 to obtain the value as the average drawing length of the information point, and take 20% of the average length as a margin. Otherwise, unnecessary material waste will be caused.
In most designs, the horizontal wiring subsystem is designed in the ceiling, wall or floor, so the horizontal subsystem can be considered as an unchangeable, permanent system. During installation, pipes and cables with excellent performance and reliable quality should be used as far as possible to ensure that users will not damage the building structure in the future. Good installation quality can make the horizontal cabling subsystem always ensure good working condition and stable working performance during its working cycle, especially for high-performance communication cables and optical fibers, the quality of installation has a particular impact on the opening of the system Obviously, the author believes that in the installation of cables, the EIA/TIA569 standard should be strictly observed.
Finally, in the Category 6 cabling system engineering, all equipment and wire products need to use Category 6 standards, otherwise it will not only reduce the performance of the entire Category 6 cabling system, but also lead to incompatibility between equipment and system paralysis.
