The wiring construction of the horizontal subsystem

The horizontal subsystem completes the function of connecting from the wiring room to the work area information export line. It adopts the scheme of the light prefabricated cable bridge of the hanging item to provide mechanical protection and support for the horizontal line system.

The assembly groove cable bridge is a closed slot that is installed in the suspension item. It is attracted from the weak electric well to the rooms with information points, and then the line tubes of different specifications in the wall will be Leaded to the dark -loaded iron box.

The wiring of the comprehensive wiring system is star -shaped, and the cable amount is large. According to the standard wire groove design method, the capacity of the wire groove is determined according to the outer diameter of the horizontal line.

That is: the horizontal cross -sectional area of the wire groove = the sum of the cross -sectional area of the horizontal line*3

The wire grooves can be selected according to the situation. In order to ensure the turning radius of the cable, the wire groove must be equipped with a branches of the corresponding specifications to provide the routing of the line routing freely.

If you cannot determine the accurate location of the information export, you can first put the cable plate in the ceiling when you pull the line. After the specific location is determined, it can be led to the export of each information.

The horizontal wiring system of Dongguan Exhibition Center adopts six types of UTP cables. According to the currently promulgated ANSI/TIA/EIA 568 B-1 six types of wiring standards, the six types of cables should be paid attention to:

Do not cut the copper core when peeling

There must be no sharp bend or knot

Avoid straining the outer skin

The cable cannot be twisted or distorted

The curved radius cannot be less than 4 times the cable outer diameter

During the specific construction, you cannot pull the line: a single 4 pair of twisted tension ≤ 10 kg; the two 4 pairs of twisted tension ≤ 15 kg; the multiple 4 pairs of twisted tensile force ≤ 40 kg. Do not bundle multiple twisted lines into a line, which will increase the string of lines.
