Key points of data center machine room cabling construction

There are two types of cabling system, "Tian" and "well". The "field" shape is more suitable for the layout of the circular machine room, and the "well" shape is more suitable for the layout of the vertical and horizontal machine room. Its position can be arranged in two places under the floor and the ceiling, each has its own characteristics. The following questions are discussed respectively in the process of wiring.

1. The design of the frame is reasonable and the proper bending radius of the cable is ensured. When the upper and lower sides go around the other grooves, the turning slope should be gentle. If we want to pay attention to whether the ends of cables hang down, we can also cover the cover without damaging the cables.
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, during the whole construction period, the process flow will be announced in time, and the supervisors of each work should communicate well. We will inform the first party immediately after finding the problem and finish the task in time.
6. If the unshielded twisted pair is installed, the docking site is not high, and the ground can be connected to the main line that is connected to the cabinet.
7, the size of the line groove is determined as follows: the cross section of the line slot remains 40% of the surplus amount to be expanded, and the cross section of the ultra 5 twisted pair lines is 0.3 square centimeters. When the line slot is installed, attention should be paid to the isolation of the strong wire grooves. The wiring system should avoid more than 3 meters in parallel with the unshielded and less than 20cm power lines. If can not be avoided, the section of the line slot need to take shielding isolation measures. The cable pipeline entering the furniture is from the nearest ceiling line down the wall to the ground, and from the ground boring slot to the furniture partition.
There should be no burr in the transition of the pipe groove and the interface should be smooth.
A line box must be left for more than two bends.
The wall socket should be installed from the ground 30 cm above the bottom box and other remained high, parallel.
Galvanized thin walled steel pipe or PVC.
