Water Proof Flexible Size Electromagnetic Communication Rack Cabinet YH9007

Wiring principles
Cabling trough: The cabinet is equipped with horizontal and vertical troughs according to the installed equipment. The design of the fixing holes for the vertical cabling is better, and the horizontal direction must be taken into consideration when considering the vertical direction. This can well fix the cables in various directions in the cabinet. The slot should be flat, no distortion, and the inner wall should be smooth and free of burrs. The connection of the trunking shall be continuous without interruption. The fixing point of each trunking shall not be less than two. There shall be fixed points at the corners, branches and ends, and shall be fixed close to the wall. The interface should be straight and tight, and the groove cover should be complete, flat, and free from warping.

Do not have excessive cable bend radius.

In the wiring construction, due to the limited space of the wiring trough, such a bending radius is very easy to occur, but in the national-related: GB50311/GB50312 and EIA/TIA 568B ISO/IEC and other standards, the twisted pair folded Curvature is strictly required. The bending radius of the cable must not exceed 8 times the bending radius of the cable itself. Obviously, the construction in the figure is not standardized. The consequence of this is a drop in the performance of the cable. Over time, excessive bending over time can destroy the electrical performance of the cable. Although the outer sheath layer of the protection cable does not appear in the short-term, the life of the outer sheath is greatly shortened due to changes in the objective conditions such as weather and temperature, which affects the service life of the cable.
Separate strong and weak electricity. The communication cable is different from the power cable. When the power cable generates electromagnetic waves, it will affect the communication performance of the communication cable and cause data confusion. This prevents normal communication.

The cabinet cabling must not have too many cable spare redundancy.
The bundled cables cannot be tied tight together.
Standard and neat cabling increases the appearance of the entire room and horizontal area, making the entire system look beautiful, but the communication cable core is generally fine. When multiple strands of cables are laid together, if too tightly bundled together, crosstalk easily occurs. This is not worth the loss of the cable itself. In addition, if the cable is tightly strained for a long time, the outer sheath of the cable may be easily broken.

The cable management board is used for multiple cables.
Four dustproof inlet holes are provided on the top and bottom of each cabinet, with two front and two rear. Take two power cables and two data cables. Use a sponge and a rubber pad for dust prevention to prevent the cabinet iron from scratching the cables.
After installation, the fireproof mud must be used for fireproofing.
All communication cables under the floor must be protected by PVC pipes. In all cables under the floor, every 3M must be tagged and used on the PVC pipe.
Cable laying should be performed using N+1 redundancy. More than one set of spare cables must be reserved.
