Shielding system used in integrated wiring

In order to prevent external electromagnetic interference and external electromagnetic radiation of the system, the integrated wiring system will adopt corresponding measures. This measure is generally protected by a shielding system. The use of shielded and unshielded wiring in integrated wiring is the most talked about topic. Because before the emergence of 10G applications, North American users used more unshielded cabling systems, while European users used more shielded cabling systems.

Integrated wiring shielding system

With the advent of 10G applications, the situation of using shielded and unshielded systems has changed a lot. Taking the five types of systems as an example, according to the investigation of relevant authoritative organizations, the proportion of shielding systems used in integrated wiring projects has increased a lot in recent years. There are three main reasons.

The first reason is that the requirements for network security reliability are increasing day by day. Due to the increase of operating frequency and the increase of electromagnetic interference sources, it is easy to generate electromagnetic radiation or electromagnetic interference. On the one hand, the information may be lost due to electromagnetic radiation, and the safe operation of the information network cannot be guaranteed; on the other hand, due to external electromagnetic radiation, it will directly affect and interfere with the normal operation of other systems.

The second reason is that the sources of electromagnetic interference are increasing day by day, so the objective environment makes the transmission conditions of the communication network rapidly worse. According to the information transmission requirements of the integrated wiring system, in and around the intelligent building, if there is an electromagnetic interference source, especially a mobile communication system, the electromagnetic interference generated is extremely serious. In this case, protective measures must be taken.

The third reason is that the transmission rate of the communication network increases rapidly. Due to the increase of the working frequency, it is easy to generate external electromagnetic radiation and receive external electromagnetic interference.

It can be seen that it is extremely important to adopt protective measures in the integrated wiring system. In addition to anti-electromagnetic interference, it is also necessary to prevent electromagnetic radiation. Therefore, in the specific design of the integrated wiring system project, according to the actual situation of the project and the requirements of the construction unit, as long as any one of the above requirements is proposed, it should be carefully studied, and the system with shielding performance should be selected in the design and take corresponding measures. protective measures are extremely necessary.

To sum up, it is very necessary to use a shielding system in an integrated wiring system, because in addition to anti-electromagnetic interference in the wiring, it is also necessary to prevent electromagnetic radiation. In the construction of the project, we must carefully study how to adopt the shielding system scheme according to the actual situation of the project and the requirements of the construction unit.
