Why do you need to use a Shielded Network Cable?
A shielded wire is a transmission wire that uses a metal mesh braid to wrap the signal wire. The braid is generally red copper or tinned copper. The shielding layer of the shielded wire needs to be grounded, and external interference signals can be led into the ground by this layer.
The shielded wire is a wire with a metal braid shell specially used to reduce the influence of the external electromagnetic field on the power supply or communication lines. This kind of shielded wire also has the function of preventing the electromagnetic energy from radiating outward from the wire.
What is the role of shielded cables?
To combat electromagnetic noise interference on electrical circuits, a very important way is to use shielded cables. A shielded cable is a cable in which one or more (mutually insulated) wires are wrapped by a common conductive layer. This common conductive layer is the shielding layer of the cable, which is generally composed of braided strands of copper (or other metals, such as aluminum), non-woven spiral windings of copper tape, or conductive polymer layers.
Use of shielded network cable
It is precise because of the structure of the shielded network cable that its purpose is determined. Shielding is to reduce the impact of external electromagnetic interference on data transmission. It is often used in the computer room environment with complex electromagnetic environments and strong interference.
The interference environment will cause the network cable transmission signal to be intermittent or even interrupted, and the signal cannot be transmitted normally. The use of shielded network cables can resist interference, maintain normal transmission, and have good confidentiality performance. The shielding structure of shielded wiring has inherent advantages in reducing mutual interference between cables.
It can not only shield external electromagnetic signals, but also aluminum foil. The electromagnetic leakage of the cable itself is blocked, no interference signals are emitted to affect the work of other cables, and information can be prevented from being eavesdropped on.
Why Use Shielded Network Cable?
Environmental problems – such as electrical noise – is one of the main reasons for the use of shielded cable in data networks. Electric motors, variable frequency drives, switching contacts, and welding equipment are many of the sources that cause electromagnetic interference (EMI). To help reduce network downtime in a production plant, it is important to know when to use shielded or unshielded cables.
Here are the top 4 reasons to use shielded cable:
Required company specification or local area requirement.
Manufacturers, distributors, and system integrators have worked extensively within certain verticals in difficult environments to install network cabling. These environments are known as ‘electrical noise’ and using shielded solutions for the communications network is documented within the company’s specifications and standards, including requirements, design guidelines, and best practices on when and how to use shielded cable. for these applications.
Proper design of the structured cabling infrastructure includes avoiding electrically noisy areas as much as possible, crossing 90 ° Vac lines, and properly connecting the cable shield to the ground system.
The infrastructure is close to a shop floor environment and data transmission is critical.
There are often data transmission lines near a plant environment that are exposed to some level of environmental stress. Enterprise-grade cable is generally not as robust as industrial-grade cable, which can be exposed to different types of chemicals, contact with fluids, near electrical noise, and bending or movement applications. Specifying the proper cable in the design phase will improve the longevity and performance of the entire system.
Motion control and high-speed automation applications.
Due to the highly noisy environment of high-speed motion control and automation systems, many manufacturers of these systems require or recommend the use of shielded cable. These systems are critical and depend on each information package. Even if the difference is only a matter of milliseconds, a high-speed machine can trip or be damaged. In extreme cases of electrical noise, the use of fiber optics is recommended.
4 Level E2 or E3 of MICE (Mechanical / Income / Climatic-Chemical / Electromagnetic).
The E2 or E3 MICE levels reflect severe levels of interference. The MICE classification system is an effective tool of the TIA-1005 standard that provides useful guidelines for determining amounts of environmental stress.
