Read this article that will take you through the difference between wrap shielding and braided shielding

Recently a new customer asked a question, he used to use the shielded drag chain cable, but the shielding effect is not ideal, at first judgment that the woven shielding density is not high impact, but we can not be presumptuous judgment, so it seems that we are not very professional, so let the customer took a picture of the peeled sheath to me, I know the problem as soon as I look, the original customer used to wrap around the shielded cable, the customer in the choice of cable to choose a cheaper drag chain cable, used in the equipment when the shielding effect is not good.

Since there is a problem, we will talk about the difference between wrap shielding and braided shielding

1. Winding shielding

• In terms of shielding effect, winding is not as good as weaving.
• The shielding effect is directional.
• shielding characteristics change when bending.
• But it has a small outer diameter, soft wire, and lower price characteristics.
• Suitable for low frequency shielding.

2.woven shielding

Weaving and twill wrap similar, in the wire mainly play a shielding role, to prevent the external electric field and the influence of magnetic fields, to improve the wire’s interference protection.Improve the wire interference defense, compared with the slant package, aluminum foil has the following characteristics.What is the difference between wrap shielding and braided shielding ?

• Shielding without directionality.
• Good high frequency shielding characteristics, suitable for high frequency shielding.
• By multi-layer shielding, the shielding effect can reach 100%.
• No change in shielding characteristics when bending.

Through the above analysis, I believe that we also have a general understanding of the two shielding methods, since it is to be used in the drag chain equipment, then it is better to use a little more expensive, it does not matter, focus on quality is the key, choose the right drag chain cable, so that you can reduce the cost of maintenance after a lot, which is more valuable than the little money you start to choose cheap cable savings, do you think?

When it comes to the use of twisted-pair cables, we all know a little bit about them. In recent years, along with the rapid grid development, twisted-pair cables, as an indispensable grid in the local grid, have been used more and more in people’s lives. So, do you know the difference between shielded and unshielded twisted-pair cables? If you don’t know, hurry up and learn about it before you lose out!

3.The difference between shielded and non-shielded twisted-pair cable

1, the internal structure of non-shielded twisted pair: only four pairs of the internal grid, no shield. Shielded twisted pair: the internal grid with a shielding layer. The shielding layer refers to the aluminum foil and braided grid.
2, performance difference Non-shielded twisted pair: no shielding jacket, only a layer of insulating glue wrapped, small diameter, flexible group grid, easier to install, and relatively inexpensive, suitable for integrated wiring. Shielded twisted-pair cable: Because of the shielding layer, the shielded grid has strong resistance to external interference. In strong interference environments, shielded wires are more stable and safe.

Non-shielded twisted-pair cable: It can only support Category 6 cabling system standards and is mainly used in general network systems with transmission bandwidth below 250MHz and no special performance requirements. Shielded Twisted Pair: Different shielding levels are available for use in special wiring environments where there are high voltage cables, strong current lines for audio equipment, etc.; it should be noted that when installing shielded twisted pair, the shield must be fully grounded; otherwise the shield itself will become the largest source of interference, resulting in a far inferior performance to unshielded twisted pair.What is the difference between wrap shielding and braided shielding ?

Therefore, unless there is a special need, only unshielded twisted-pair cables are usually used in integrated cabling systems.

[Expanded Reading: About Twisted Pair FTP STP SFTP ASTP Shield Differences] According to the different shielding methods, there are the following types of shielded twisted pair cables.

1, FTP aluminum foil shielded twisted pair advantages: greater bandwidth, strong anti-jamming performance, with low smoke and no halogen characteristics.
Disadvantages: compared to non-shielded UTP, price and installation costs are higher, and cable bending performance is slightly worse; applications: Category 6 and previous shielded systems are mostly used in this form.STP unique shielded twisted pair structure: aluminum foil layer is added to the core, and each pair of wires has an aluminum foil shield. In addition, every four pairs of standard Category 7 STP cables are combined and wrapped with a metal braided grid shield on the outside.

Advantages: Double shielding reduces signal attenuation
Disadvantages: Higher price, thicker wire diameter, and more complicated installationWhat is the difference between wrap shielding and braided shielding ?
