There are two specific ways for the wiring system in the shielded room: "Tian" and "Ting". Among them, the shape of "Tian" is more suitable for the layout of the circular computer room, and the shape of "Third" is more suitable for the layout of the vertical and horizontal computer room. Its location can be arranged in two places, under the floor and on the ceiling, each has its own characteristics. The editor of the Shenzhen shielded room manufacturer will introduce the problems that need to be paid attention to during the wiring process:
Key points of integrated wiring construction in shielded room:
1. Reasonable structure design to ensure proper cable bending radius. When bypassing other cable ducts up, down, left, and right, the turning slope should be gentle. Pay attention to whether the cover can be covered without stressing the cables after the cables at both ends are sag.
2. Pay attention to the tension control during the unwinding process. For the cable with reel packaging, it is recommended to arrange at least one worker at each end to put the reel on the self-made draw rod, and the worker at the end of the line first puts it in the reel box Pre-pull out a part of the cable for the partner to extract at the other end of the pipeline. The pre-pulled cable should not be too much to avoid multiple cables from tangling around on the field.
3. After the wire drawing process is over, the redundant cables left at both ends should be organized and protected. When coiling the wire, follow the original direction of rotation. The diameter of the coil should not be too small-the shielding window, if possible, fix it with a waste thread. Make a mark on the bridge, suspended ceiling or inside the carton to remind other personnel not to move or step on it.
4. When arranging, tying, and placing cables, the redundant cables should not be too long, and the cables should not be subjected to superimposed stress. The coils should be convolved, and the fixed ties should not be tightened too tightly.
5. During the entire construction period, the process flow should be notified in time, and the person in charge of each type of work should communicate well, notify Party A immediately if any problems are found, and complete the tasks of this type of work in time before the start of other follow-up types of work.
6. If the unshielded twisted pair is installed, the grounding requirement is not high, and it can be grounded at the main trunking connected to the cabinet.
7. The specification of the trunking is determined as follows: the cross-sectional area of the trunking is left with a 40% margin for expansion, and the cross-sectional area of the ultra-category 5 twisted pair is 0.3 square centimeters-shielding cabinet. When installing the wire trough, pay attention to the isolation from the strong wire trough. The wiring system should avoid running more than 3 meters in parallel with the strong current line without shielding and the distance is less than 20cm. If it cannot be avoided, shielding and isolation measures must be taken for this section of the trunking.
