Faced with external electromagnetic and magnetic radiation which can interfere with cables. The braided armored cable are necessary to reduce interference. The braided armored cable function include armor against electromagnetic interference.
The damage caused by this radiation are different from ordinary mechanical and chemical damage. It is a high frequency invisible radiation.
Ordinary shielding is not protective. The use of shields is necessary to reduce interference due to radiation.
What is a braided armored cable ?
The armored braided wire incorporates a trellis braiding material in the outer layer of the cable. It is used to combat electromagnetic interference. The structure consists of a driver, insulation, shielding and a sheath from the inside to the outside. The most important of these elements is the shielding layer.
The structure consists of drivers, of insulation, shielding and sheath, from the inside to the outside. The most important of these elements is the shielding layer.
There are two layers of shielding. The weaving of the mesh prevents the effects of the radiation of the magnetic field. The aluminum sheet layer prevents the effects of electromagnetic radiation.
High frequency external radiation generates losses by Foucault currents when they cross the shielding layer.
Porting the shielding layer can be connected to the earth layout driver of the shielding layer.
Ensure that external electromagnetic radiation and magnetic field radiation penetrate the ground. Play a good shielding role.
Advantages and STructure du Cable Methical BLINDE
The shielding layer has good anti-interference properties for high frequency radiation. For the low level signal, The cable line offers good protection.
The cable television cable is an example. There is a layer of metal shielding outside the cable. It guarantees the stability of TV signal transmission.
The common shielding layer consists of a copper braid, aluminum leaf and a tinned copper -sleeve sleeve.
Shield by Tre - Cuivre
Cables armored by copper braid have a good antiparasitic capacity, And the performance of the shield vary depending on the density of the braid and the number of layers.
In addition to copper, commonly used braiding materials are steel and ceramic fibers.
Braided shielding is longer to produce, But it is suitable for all frequencies of electromagnetic interference.
Shield by FEUILLE D’Aluminium
The shielding of aluminum -armored cables consists of an aluminum layer attached to the structure of the cable. Due to its low thickness, It is suitable for thin soul cables.
The finesse of the armor also makes it less resistant to electromagnetic interference than the type of armor with copper braid.
For protection against low -frequency electromagnetic interference.
Sheath Methical Treferred to Ctinned uivor
The tired metal armored cables are covered with a layer of tin on the metal surface. This layer can isolate water and oxygen. Prevents oxidation and corrosion of metal. Increases the lifespan of metal shielding.
He can effectively prevent electromagnetic interference, But its production cost is high.
What is the difference between an armored cable and an unmanned cable ?
- Different use scenarios. The braided armored cable is suitable in places where electromagnetic interference is relatively important. Unmanned cables are used in non -electromagnetic scenarios and are generally used in office networks.
- Armored cables require special connectors for connection. Unmanned cables are faster to install and require electrical security at the connection point.
- The non -armored cables are cheaper and the armored cables are more expensive.
Why is the braided armored cable important ?
Electromagnetic interference is almost inevitable today. The broadcasting towers, radars, Wireless communication equipment and thunderstorms of thunderstorms all generate electromagnetic interference.
Effects of electromagnetic interference
When armored braided cables are found in electromagnetic or magnetic fields. These disturbances may have the following negative effects on the cable.
- Electromagnetic interference. The high frequency radiation generated by external electromagnetic or magnetic fields cross the surface of the cable and penetrate inside the driver. Armor and insulation cannot prevent these interference. They affect the transmitted signal. As a result, the equipment cannot operate normally.
- frequency interference. The high voltage cable produces electromagnetic interference during the transmission process, which causes screen noises. Audio distortions and other transmissions of incomplete signals, and affects the efficiency of the transmission.
- Reduce cable life. The absence of a cable armor layer. Long -term electromagnetic interference will damage the cable and make it age, which will reduce its lifespan.
To reduce electromagnetic interference, The radiation of electromagnetic waves.
The noise current on the cable caused by the impact of the shielding layer should be used to eliminate interference.
The armored cables can effectively prevent electromagnetic waves from radiating outwards and causing interference with other cables.
At the same time, to a certain extent, They can isolate the coupling effect of internal and external electromagnetic fields.
Reduce interference between different signals and apply during multiple signal transmission cables.
For signals transmitted inside the cable. The armored braided wire can effectively guarantee the reliability and integrity of the transmission of information. It offers a good guarantee in the field of data communication.
It improves the speed and quality of the internal transmission of information.
When Uuse a Cable Treef BLINDE ?
Ilsted braided cables can effectively reduce the impact generated by electromagnetic interference compared to conventional cables. Widely used in applications with high signal levels or radiated interference.
Widely used when the level of signal quality or radiated interference are high.
In the industry, communication and other areas of machines and equipment, The sensors produce powerful electromagnetic fields.
The transmission of signals is affected, even interrupted. Which prevents equipment from operating normally . The addition of a shielding layer makes it possible to avoid such interference.
Medical equipment requires high -quality signal transmission. Unstable signals that can be fatal during surgery. This is why medical equipment generally uses armored cables to guarantee stable transmission of information.
