Shielded cables contain normal insulated conductors enclosed in a standard conductive layer with a special protective shield. This shielding distinguishes these cables from the normal unshielded variants.<\/p>\n

The shield is wrapped around the insulated conductor and is typically made of: Braided copper and similar metal strands Helical copper tape Conductive polymer<\/p>\n

What is the function of shielded cable?<\/p>\n

Shielded cables reduce and isolate data or power transmission from high-power "electrical noise" or ambient electromagnetic interference (EMI) present in industrial, engineering or manufacturing environments, and data and power transmissions can be subject to electronic interference.<\/p>\n

What is Electromagnetic Interference (EMI)?<\/p>\n

EMI is variable currents and voltages that occur regularly in the environment. We think of it as common interference that disrupts things like cell phones, TVs, or AM radios. It can be natural, inherent, or man-made.<\/p>\n

Naturally occurring EMI can be caused by thunderstorms and lightning storms, snowstorms, rain particles, and solar radiation. Natural EMI poses fewer problems to modern digital equipment than older data link and RF communications via ship, shore, and air.<\/p>\n

Intrinsic EMI is electrical noise generated within electronic devices. The thermal agitation of electrons flowing through the resistance of a circuit creates "white noise," often associated with the familiar sound of radio receiver frequencies between stations.<\/p>\n

Man-made EMI is caused by different categories of electrical and electronic equipment. Vehicle ignitions, motors, transmitters, generators, power lines, mobile phones, lighting types, etc. are examples of man-made devices that can cause EMI to power supply systems and data processing equipment.<\/p>","protected":false},"excerpt":{"rendered":"
