Blue Aluminium Foil For Cable And Wire
An important role of the data line is to transmit data signals. But when we use it, there may be all kinds of messy interference information around us. Let's think about if these interfering signals enter the inner conductor of the data line and are superimposed on the originally transmitted signal, is it possible to interfere or change the originally transmitted signal, thereby causing loss of useful signals or problems?
And these braided nets and Blue Aluminium Foil For Cable And Wire layers protect and shield the information we want to transmit. Of course not all data lines have two shields, some have multiple shields, some have only one, or even none at all. Shielding is a metallic isolation between two spatial regions to control the induction and radiation of electric, magnetic and electromagnetic waves from one region to another.
So what are the shielding materials? Aluminum foil Mylar uses soft aBlue Aluminium Foil For Cable And Wire and polyester film as raw materials, and is compounded by gravure coating. After the aluminum foil Mylar is mature, it is slit and rolled. It can be adjusted with glue, and can be used to assemble shielding and grounding after die-cutting of aluminum foil Mylar.
Aluminum foil Mylar is mainly used to shield high-frequency electromagnetic waves to prevent high-frequency electromagnetic waves from contacting the conductors of the cable to generate induced current and increase crosstalk. When the high-frequency electromagnetic wave touches the aluminum foil, according to Faraday's law of electromagnetic induction, the electromagnetic wave will adhere to the surface of the aluminum foil and generate an induced current. At this time, a conductor is needed to guide the induced current into the ground to avoid the induced current from interfering with the transmission signal.
Wires using aluminum foil as shielding layer generally require that the repetition rate of aluminum foil should not be lower than 25%. The largest number of applications are currently on network wiring. This type of network cable is mainly used in hospitals, factories and other places with strong electromagnetic wave radiation or a large number of strong electrical equipment; in addition, it is also used in governments and other areas with high network security requirements.
