What precautions must we not ignore in the application of wiring systems? We're going to tell you next.

Analysis of key points in grounding design of wiring systems
Improving integrated wiring grounding systems will be a difficult and time-consuming task for most engineering and technical staff. You need to know what to consider when designing the grounding of the integrated wiring system.

How to learn things to note when applying cabling systems

1. All shielding layers in the integrated wiring system should maintain continuity when using shielding measures. Pay attention to ensuring that the relative position between the wires remains unchanged. 
Connect the wiring equipment and user end to the ground based on the specific situation. Grounding at both ends: should be connected to the same ground body as much as possible.

2. The cable entering the building can be affected by lightning, power supply issues, or rising ground potential. In order to protect the cable, we need to use protectors. To protect it, we need to use protectors.

3. When the line is in dangerous environments, it needs protection from overvoltage and overcurrent.
(1) Dangerous effects caused by lightning strikes;
(2) Power lines with working voltage exceeding 250V touch the ground;
(3) Power failure caused by ground potential rising above 250V;
(4) AC 50HZ induced voltage exceeds 250V.

4. Gas discharge tube protectors should be used for overvoltage protection of integrated wiring systems. The gas discharge tube protector has two sealed electrodes in a ceramic shell. They have a gap between them and are filled with inert gas.

5. The over-current protection of the integrated wiring system should use a self-restoring protector. Since one or another voltage may appear on the cable, if the connecting device provides a low-resistance path to ground, it will not be enough to cause the overvoltage protector to operate, and the current generated may damage the equipment or cause a fire.

Notes on cabling systems:
Cabling systems must be moisture-proof
Water getting into data cables can affect their ability to handle fast data applications. Sometimes, cables close to the maximum length allowed by the standard can break if they come into contact with water. When a cable gets wet, its insulation changes, which affects impedance and other factors like attenuation and return loss.

For outdoor environments with varying degrees of fog or water, the designed cables will take waterproof measures.
The impact of water intrusion also depends on the source of the water and the timing of the intrusion.

Replacing a damp cabling system is time-consuming, costly and disruptive. Obviously, the best way is to protect your cables from moisture. Companies in risky areas should consider moisture risk when designing networks and also for existing cable networks.

If possible, cables should be suspended in ducts in the ceiling space, which reduces the risk of moisture more than running under the floor.

Do not locate telecommunications rooms or equipment rooms in basements when using cabling systems. If you struggle with being alone, particularly when near a river, consider using racks or cabinets. Another option is to create embankments that can redirect water to safer areas.

When cables become damp, the actions to be taken depend on the number of cables affected, the cost of replacement compared to the risk of business loss of not replacing the cables, etc. Cables that have had water ingress through the beginning of the cable through capillary reaction should be replaced directly; cables that have been severely affected by water intrusion through the outer sheath may also need to be replaced.

That’s all we want to tell you about the things to note when applying cabling systems. I hope it will be of some help to you who are reading this article.
