The shielded cable is a special cable used to isolate the electromagnetic field noise source from sensitive equipment and cut off the propagation path of the noise source. Shielding includes active and passive shielding. Active shielding is to prevent the noise source from radiating outward, and it is the shielding of the noise source. Passive shielding is preventing sensitive equipment from being interfered with by noise sources. And it is a shield for sensitive equipment. PVC shielding wire has become one of the most popular using electric wires in the market. Today’s article will introduce some knowledge about shielding copper wire. Below is the main topic of this article.
First of all, we will introduce what is a shielded wire.
A shielding wire is a kind of transmission electric wire using a layer of metal mesh braiding to cover the signal cable. The shielding braid layer is usually alloy, copper, or tinned copper with different densities. The shielding layer of the shielding wire needs to connect grounding. So that the external interference signals can guid into the earth by this layer.
Its structure is also simple, it includes ofc copper conductor, PVC insulation, foil shielding layer, metal mesh shielding layer, and PVC outer sheath. For braiding metal mesh shielding layer, there are also different materials. Such as alloy, copper, and tinned copper with different densities for your choice. PVC shielding wire also includes flexible shielding cable and solid shielding cable. The flexible copper cable includes RVVP shielded cable, and solid copper PVC wire include KVVP shielded cable. Here are pictures of them.
Now we have understood what is a PVC shielding wire. This kind of copper cable gained so many good reputations and markets, and it must have some reasons people use it. Now, we will introduce these reasons in the next part.
PVC shielding wire has shielding mesh and alloy shielding layer around the conductor, there will haven’t any signal leakage, and at the same time, it will not be disturbed by external electromagnetic interference. It can well mitigate EMI, and ensure the safety of information transmission. So it is widely suitable for occasions that need strict signal shielding and information security.
At the same time, compare with other signal protection power equipment, PVC shielding electric wire has the advantage of cheaper cost and long service time. It is easy to install and maintain. So many users like to use shielding wire as their common wire.
In the market, there is also another kind of popular electric wire-unshielding electric cable. What’s the difference between these two kinds of wires is also the main focus for some users.
There are many different electric cable suppliers in the market, how to choose a reliable one also has become an important problem for all cable users. At the final of this article, we will recommend a reliable supplier to you.
