In the wiring project, the level of construction level directly affects the performance of the system, and it is necessary to reinstate the serious ones, such as the wrong slot, the color label on the wiring frame, and the number of the number. For example, the cable through the steel pipe, crossing the transition box, etc.) is a relatively common technology. I now summarize the more mature experience in this regard for your reference.
The threading technology is a relatively common technology in the wiring. In order to ensure that the cable is not scratched and causing "short circuit", the plastic guards must be placed in all steel pipe mouths. A feasible method is that threading personnel should carry "guards" at any time during construction. When needed, they can be placed at any time to avoid "lazy" because there are no "guards" at hand. When the vertical cable is transferred to the vertical steel pipe through the transition box to the lower layer, it is necessary to tie the suspension in the transition box to avoid the cable weight on the inner cable of the corner, because this will affect the transmission characteristics of the cable. The cables in the vertical wire should be tied up once a meter. The cables in the line groove should be straight, no entanglement, and the length of length should be consistent.
Regarding the "remaining line" problem, the "remaining line" of the cable at the wiring box should be consistent and not too long. It is best to group the remaining lines according to the packet table, straighten to the line groove exit, and the distance between the tie point is not more than 50cm. It should be noted that the wire or hard power source line should not be bundled.
Regarding the problem of the label, the cable is labeled according to the computer's floor plan. Each label corresponds to a 4 pair of core wires. The corresponding room and socket position cannot be mistaken. In the implementation, this is the most error -prone place. The experience is that the label position at both ends is 25cm from the end of the end. The light -colored plastic tape is pasted, and the tape is tangled with an oily pen or a paper number.
In addition, we must wear a backup line at a ratio of 3%. The spare line is placed in the trunk groove, and at least one spare wire is each layer. After the thread is completed, all 4 pairs of core cables should be fully tested. The test can be tied to the following methods to peel all the cores of the cables at both ends and expose the copper core. Dial the digital multimeter to the interrupt test file on one end, the two tablets receive a pair of cable cores, and the pair of cable cores are frequently and briefly exposed to the other end. If you can hear the intermittent sound with the surface, the test passes, and the 4 pairs of cores of each cable must be tested. Through this test, you can find the problems of disconnection, disconnection, and marking.
During the wiring period, there is another thing to note that when the cable is not put in place after the cable is pulled out, if the construction is to be suspended, the cable should be carefully entangled and retained properly. This is a lot of no specifications
