Key points of construction of computer room wiring system

Wiring system specific way there are "Tian" and "well" zigzag two kinds. One of the "field" font is more suitable for the ring room layout, "Well" font is more suitable for the vertical and horizontal layout of the room. Its position can be arranged under the floor and ceiling two places, each has characteristics, the following discusses the wiring process to pay attention to the problem:

Main points of integrated wiring construction

1, the frame design is reasonable, ensure the appropriate cable bending radius. The top and bottom around the other trough, the turn slope should be gentle, pay attention to both ends of the cable droop after the force can also be in the pressure loss of the premise of the cable cover.

2, the line in the process is mainly to pay attention to the tension control, for the cable with reel package, it is suggested that at least one worker should be arranged at both ends, and the reel should be set on the self-made pull rod, and the workers who put the line end will first pull out some cables from the reel box for the collaborators to extract on the other end of the pipeline, and the line cannot be Avoid multiple lines tangled around the site.

3, after the pull line process is over, left at both ends of the redundant cable to organize and protect good, the coil should follow the original direction of rotation, winding diameter should not be too small, if possible with the use of waste thread fixed in the bridge, ceiling or carton, do a good mark, remind others not to move.

4, in finishing, lashing, placing cable, redundant cable not too long, do not let the cable superimposed force, the coil homeopathy consolidation, fixed Zahan not too tight.

5, in the entire construction period, the process of timely notification, the various types of persons responsible for communication, found that the issue immediately notify party A, in other follow-up work before the start of the task of timely completion of this type of jobs.

6, if the installation of unshielded twisted pair, the grounding requirements are not high, can be connected with the cabinet of the main groove ground.

7, the specifications of the wire groove is to determine: the cross-section of the wire groove left 40% of the surplus for expansion, Super 5-type twisted-pair cross section area of 0.3 square centimeters. Groove installation, should pay attention to the isolation of strong wire groove. Wiring system should avoid with strong electric line in no shielding, distance less than 20cm parallel walk more than 3 meters. If it can not be avoided, this section of the groove needs to take shielding isolation measures. The cable pipeline into the furniture from the nearest ceiling trough to the ground along the wall, and from the ground boring groove buried under the furniture partition.

Pipe Groove Transition, interface should not have burrs, groove transition to smooth.

Wire tube More than two elbow must be left in the separation box.

The wall-mounted bottom box should be 30 centimeters above the ground and be kept parallel with other bottom boxes.

Galvanized thin-walled pipe or PVC for wire tube

Computer Room Wiring System

The software and hardware in the interconnected age are very important, but the basis of their stable operation--the room is more important. The computer room should have high availability, high reliability, high security, scalability and rich network resources and other characteristics. The following will focus on the computer room wiring. More Wonderful content: http://www.bianceng.cn/Network/zhbx/

The wiring system of the computer room directly affects the function of the future room, the general wiring system requires the protection distance as short and neat as possible, arranged in order, the specific way has "Tian" and "well" zigzag two kinds. Among them: "Tian" style is more suitable for the ring room layout, "Well" font is more suitable for the vertical and horizontal layout of the room. Its position can be arranged under the floor and ceiling two places, each has characteristics, the following are discussed separately:

1, floor wiring: This is one of the most common wiring, it takes full advantage of the floor under the space, but to pay attention to the floor under the water leakage, rodent and heat dissipation, but also to ensure that the bottom of each cabinet to dig the corresponding threading hole (including Floor and groove).

2, ceiling wiring: The wiring is particularly suitable for the wiring of the computer room, is also very popular, this way in the ceiling contains a variety of wiring power, weak wiring, in each cabinet to cut the corresponding threading holes (including flooring and wire slots), of course, also pay attention to leakage, rodent and heat dissipation.

Specific wiring of the content are: power wiring, weak wiring and grounding wiring, where the power wiring and weak wiring are placed in the metal wiring groove, the specific metal wiring slot size can be based on the number of lines and consider a certain amount of development (generally 100x50 or 50x50). The distance between the power cord groove and the weak wire groove should be kept at least 5 centimeters and not cross with each other to prevent electromagnetic interference between them. The following will be explained:

A, Power wiring: In the new room decoration for power wiring, should be based on the entire room layout and UPS capacity to arrange, in the planning of each cabinet and equipment near the arrangement of the corresponding power outlets, the capacity of the socket should be based on the power of access equipment to set, and leave a certain amount of redundancy, generally 10A or 15A. The line diameter of the power supply should be based on the capacity of the power outlet and retain a certain capacity to buy.

B, weak wiring: Weak wiring mainly include coaxial thin cable, five types of wire and telephone lines, wiring should pay attention to each cabinet, equipment behind the corresponding cable, and should consider the future development needs, a variety of cables should be categorized with nylon braid strap.

C, grounding wiring: Because the new room is high performance computer and network communication equipment, so the grounding has strict requirements, grounding is also to eliminate public impedance, to prevent capacitance coupling interference, protection equipment and personnel safety, to ensure that the computer system stable and reliable operation of the important measures. In the room floor should be placed in the signal grounding copper row, in order to provide a variety of computer room grounding needs, copper and then a dedicated line to access the weak electrical signal grounding system.

About 6 types of cable wiring

1. If there are redundant cables between the 2 terminals, they should be cut as long as they are needed, and should not be rolled up and bundled.

2, the cable joint at the counter-winding line of the distance should not exceed 2cm, too long will cause a large near-end crosstalk.

3. At the joint, the outer protective layer of the cable should be pressed in the joint and not outside the joint. Although the line cable is subjected to external tension, the whole will be force, but if the external protective layer is pressed outside the connector, then the force will be mainly the cable and the connection of the metal part of the connector.

4, online cable wiring construction, cable tension is a certain limit, generally 9kg or so. Too much tension will damage the symmetry of the cable.

5, because the outer diameter of the six type of cable than the general five types of line coarse, in order to avoid the winding cable (especially in the elbow), in the pipeline design must pay attention to the diameter of the filling, the general diameter of the 20mm pipe to put 2 six type line is advisable.

About embedded Pipelines

1, a variety of cables even if the pipe embedded in the future will not necessarily be able to ensure that no replacement, you can handle this. In the corner part (the position of the kicking brick), dig a groove, kick brick installation and wall adhesion 2/3. A number of distances per grid, installation of an active kick brick, the installation of the activity kick brick method is embedded in the wall in the wood side. The movable kick brick may drill the fixed hole according to the need, uses the copper or the stainless steel wood screw to fasten. This makes a pipe in the wall (the lowest part of the pipe exceeds the final plane 2-5cm). In the future, if you need to replace the weak electricity cable only need to remove the active kick bricks. The buried pipe crossing the ground is best to exceed the final plane 2-4cm. The additional need for the first floor is to consider flood and drainage problems.

2, through the middle of the room embedded pipe. Both ends are processed beyond the final plane 2-5cm. Room mainly draw a good line map, after the completion of construction to keep good (for a number of years after maintenance basis).

3, pipe construction caused by the damaged cable insulation to replace, do not. General decoration contract to indicate threading requirements, cable insulation damage responsibility to distinguish.

Cable in advance, and focus on the right place (usually outdoor cable entrance), according to the actual demand, flexible combination, use, support telephone/fax, Internet, cable TV, home theater, music appreciation, video on demand, fire alarm, security anti-theft, air-conditioning control, lighting control, gas leak alarm, water/electricity/ Gas three-meter automatic cc and other applications.
