Data center migration, wiring system specific way has "Tian" shape and "well" glyph two kinds. The "Tian" glyph is more suitable for the annular computer room layout, and the "well" shape is more suitable for the layout of the vertical and horizontal computer room. Its location can be arranged in the floor and ceiling two places, each has its own characteristics, the following are discussed in the wiring process should pay attention to the problem:
1, the frame design is reasonable, to ensure the appropriate cable bending radius. When the upper and lower sides turn around the other line grooves, the turning slope should be gentle, and pay attention to whether the ends of the cable sag and force can cover the cover plate without damaging the cable.
2, put the line process is mainly control the tension, the tape reel cable, at least two suggestions to arrange for a worker to scroll in Guyed pole homemade, line end workers first pulled out a part of the cable from the scroll box for the pre, in the pipeline are extracted at the other end. Pre pull out of the line can not be too much, to avoid entanglement with a plurality of lines on the ground around.
The end of 3, after the process of cable, cable ends for redundancy to collate and protect the disk line along the direction of rotation of the original coil diameter, not too small, if possible with waste thread fixed on the tray, ceiling or cartons, do mark, to remind other personnel do not move, do not step on.
4, in the finishing, binding, cable placement, redundant cable should not be too long, do not let the cable stress superposition, coil with consolidation, fixed rope not looking too tight.
5, in the whole construction period, the process flow timely notification, each job person in charge of communication, found the problem immediately notify Party A, in other follow-up work before the beginning of the completion of the task of this type of work.
6, if the installation is unshielded twisted pair, the grounding requirements are not high, can be connected to the main line slot connected to the cabinet.
7, the specification of the line slot is to determine: the cross section area of the line slot to remain 40% surplus to expand, the cross section area of 5 types of twisted pair is 0.3 square centimeter. Attention should be paid to the isolation of the strong wire slot when installing the slot. The wiring system should avoid parallel lines more than 3 meters parallel to the strong line without shielding and distance less than 20cm. If it can not be avoided, the line slot should be shielded and isolated. The cable line entering the furniture is from the nearest hanging line slot to the ground along the partition wall, and from the ground boring groove buried pipe to the furniture partition.
The groove transition and interface should not have burrs, and the groove transition should be smooth.
More than two elbows must be left in the line box.
The wall socket should be installed from the ground 30 cm above the bottom box and other remained high, parallel.
Galvanized steel tube or PVC. is used for the pipe line
