Advantages and disadvantages of Ground Line Slot cabling and precautions

Overview of ground groove cabling

The horizontal sub-system's ground trough cabling method is to directly route the cables from the weak current well to the ground trough, or the branch pipe from the distribution box to the information outlet on the wall ,. As the ground strip box or split box directly goes through the ground cushion, This method is suitable for places that need to be separated or large.

In this way, the rectangular trough is directly inserted into the ground cushion, every 4 ~ 8 m installs a line box or line box (the line box acts as a line box on the branch) until the line box at the information outlet.

The horizontal sub-system has the following advantages:

1. The distance between the information outlet and the weak current well is not limited. Ground Line slots every 4 ~ 8 m is connected to a split-line disk or a egress disk. It is very easy to pull the cables during deployment, so the distance is not limited.

2. strong and weak current can be the same route. Strong and weak current cables can be routed along the same path from adjacent ground slots, and can be connected to their respective sockets in the same line box. Of course, the ground trough must be grounded and shielded, and the product quality must pass through.

3. It is suitable for large-size office spaces. For example, the area of the office or business hall is very large, and the computer is far away from the wall. It is obviously inappropriate to use a long jumper to directly connect to the information and power outlets on the wall. At this time, leave an outbox near the ground trough to solve the problem of network access and power supply at the same time.

4. Improve the grade of commercial buildings. As a modern management model, only high-end buildings can provide such offices without messy and orderly cables.

The horizontal sub-system has the following Disadvantages:

When the ground trough is made in the ground cushion, the thickness of the cushion must be at least 6. Scm, which is unfavorable for minimizing the baffle and cushion thickness.

Because the ground trough is made in the ground cushion, if the floor is relatively thin, it may be hit by the boom during the process of filling the ceiling, affecting the use.

It is not suitable for scenarios where there are many information points on the floor. With the increase in the number of information points, a large number of cable slots are required, and the door width is far from meeting the needs. Therefore, a hole must be opened on the load-bearing wall, which is not allowed by the construction safety regulations. In addition, when there are more cable slots on the ground, the chance of being hit by the boom increases accordingly. Therefore, when there are more than 300 information points in the same cabling place, both the ground trough and the ceiling trough should be used to relieve the pressure on the ground trough.

Not suitable for stone floors. The refined marble floor cabling box will greatly affect the visual effect. Therefore, the path of the ground trough should avoid passing through the stone ground, or do not set the outline box and the distribution box on it.

Expensive. For the sake of appearance, the ground wire box often uses copper or stainless steel products. Therefore, the price of a wire box is 300 ~ 400 yuan, hundreds of times higher than the wall-type embedded wire box. In general, the cost of the ground trough is 3-3 of the ceiling trough ~ 5 times.

Pay attention to the following points in the design of Horizontal sub-system Line Slot cabling:

When selecting Integrated Wiring products, you should select those manufacturers with engineering experience. Their products should pass the national electrical shielding test to avoid the impact of strong and weak circuits on data. When laying ground to the cable trough, the manufacturer should send technical personnel on-site guidance to avoid the problem discovered after laying the cushion and affecting the construction period.

Design According to the office furniture layout provided by Party A to avoid office furniture blocking at the exit of the ground trough. When there is no office furniture diagram, the ground trough should be uniformly arranged at the ground exit. For rooms with anti-static floors, you only need to deploy a distribution box. The distribution box is laid under the electrostatic floor.

The trunk part of the ground trough should be placed in the cushion of the corridor as much as possible. When there are many floor information points, both the ground trough and the ceiling trough should be used.
