Do you understand the threading skills in the integrated wiring?

In terms of cabling technology, threading techniques are common, such as passing through steel tubes, passing through transition boxes, and so on. In these aspects, attention is needed. In order to ensure that the cables are not scratched and thus cause a "short circuit," plastic guards must be placed on all the steel pipes. How can we do it?

In order to prevent the cable from being scratched, we should carry a “guard” on the body when it is under construction and place it wherever it is needed, so as to avoid being “slacked” by the fact that there is no “guard” at hand. When passing through the transition box, avoid that the weight of the cable is fully pressed on the inner cable of the corner, otherwise the transmission performance of the cable will be affected. At this point, it should be done. When the vertical cable passes through the transition box and goes into the vertical steel pipe to go down one layer, the suspension shall be tied in the transition box, and the cable in the vertical slot shall be suspended once per meter, and the cloth in the slot The cables should be straight, untwisted, and have the same length.

In this case, the "overline" problem is involved. The length of the "overline" at the wiring box must be the same, and it must be ensured that it is not too long. It is better to group the remaining lines into grouping tables and export them from the trunk. Straighten and tie it well, and the spacing between the tie points is not more than 50cm. It is worth noting that iron wires and power cords cannot be used for lashing.

In the threading process, the labeling is very important, and its labeling must never be wrong. The cables are numbered according to the floor plan of the computer. Each label corresponds to a 4-pair core, and the corresponding room and socket locations cannot be mistaken. The marking positions on both ends are 25cm from the end, light plastic tape is applied, the upper part is marked with an oily pen or a paper number is attached, and then the transparent tape is wrapped.

After the threading is completed, all four pairs of core cables should be fully tested for continuity. In addition, we should also reserve reserve lines. Generally, we must use 3% of the backup line. The backup line should be placed in the main trunk and at least one spare line should be used on each floor. The test usually uses a digital multimeter to strip the cores of both ends of the cable to expose the copper core. At one end, the digital multimeter is dialed into the continuity test file, the two tables are pen-connected to a pair of cores, and the pair of cable cores are contacted frequently and briefly at the other end. Being able to hear intermittent sounds means that the test passed.
