Low voltage network wiring cabinet

The general requirements of weak current network cabinet go line, weak current generally refers to the dc or audio and video lines, network lines, telephone lines, general voltage within 36 v dc voltage, commonly used in computer local area network (LAN) system, for each signal data transmission between devices have the effect of the decision. Therefore in the weak current line, go for network cabinet internal line has some requirements.
generally weak current network cabinet bedding line steps are as follows:
1, the cable root exposed areas began to tie up with cable tie, cable if the cable is too much in secret number from the middle into two or more, but need to make sure that your network cable of each part is continuous, because it'll be easier for the next step work.
2, according to the need to make most of the Internet started to use wiring board line, the use of the wiring board is the cable according to an agreement through the wiring board strips on the back of the wiring board, in accordance with the two successive cable and wiring board back together with cable tie up, every two tied together requires a dislocation, is too much, don't side by side every two best tie up and down a little distance, after two consecutive up, began to six string together together, took an average of once every half a metre to plunge, note of time attention and tidy, not careless tied together to give a person the feeling of not harmonious.
3, using the line board has been down to down, right line board has also been used on the back of the tie wrapped ( Half a metre a firm) 。 Last six a first position in the cable tail about one meter, fasten the later two root is a begin in the near distance, of course, or in accordance with the order. After every two root well into the second half of the m tied again using the same method again, is advantageous to the next play distribution frame.
4, distribution frame is to hit below this link, as a result of the above work is done after the cable has been very clear, and the cable to the cabinet began to put on a piece of work outside the stage start on line pressing work in groups of three. Carried out in accordance with the pre-arranged position wire is not easy to get wrong. Line pressing here no longer describe the specific process step.
5, rallied the distribution frame to test, test by giving installation cabinet, if discover if through the contact point is carefully checked and module and the problem such as line sequence, for all at once, after all pressed flux measurement module installed on the rack, installed in accordance with the original plan for cable tie, do clean horizontal flat vertical. The connectivity of each point, if still cannot pass on the notes log should be recorded.
weak current and high voltage, low voltage of the processing object mainly is information, the information transmission and control, its characteristic is low voltage, small current, power, high frequency and the main consideration is the effect of information transmission problems. So, weak current network cabinet walk line voltage, it is important to note that circuit voltage is too big, lest cause unnecessary consequences.
