The shield can be made of braided copper wire (or similar metal), a spiral of copper tape, or some other conductive polymer. The importance of shielded cable cannot be overstated.<\/p><p>Shielded cables are generally thicker and more rigid than unshielded cables. They also require more care when used. Shielded cables are most often seen in industrial settings and installations because other nearby equipment may generate electromagnetic interference (EMI).<\/p><p>Unshielded twisted pair cables do not have an internal shield to reduce EMI. Instead, they are designed to eliminate EMI by using a twisted pair of wires. These cables are lightweight and thin, making them best suited for indoor use in office environments for LANs or similar network cable systems. They are also less expensive than industrial cables. However, they are not always suitable for industrial environments that require a lot of power or often use heavy equipment.<\/p><figure class=\"wp-block-image aligncenter size-full\"><img decoding=\"async\" class=\"wp-image-5436 lazyload\" src=\"data:image\/gif;base64,R0lGODlhAQABAIAAAAAAAP\/\/\/yH5BAEAAAAALAAAAAABAAEAAAIBRAA7\" data-src=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/03\/1-7.jpg\" alt=\"\" \/><noscript><img fetchpriority=\"high\" decoding=\"async\" width=\"500\" height=\"465\" class=\"wp-image-5436 lazyload\" src=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/03\/1-7.jpg\" alt=\"\" srcset=\"https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/03\/1-7.jpg 500w, https:\/\/www.ray-tron.com\/wp-content\/uploads\/2023\/03\/1-7-300x279.jpg 300w\" sizes=\"(max-width: 500px) 100vw, 500px\" \/><\/noscript>\r\n<figcaption class=\"wp-element-caption\">Twisted-pair cable with symbols. Foil shielded cable.<\/figcaption>\r\n<\/figure><p>What is the purpose of shielded cable?<\/p><p>Shielded cables are used to protect data transmitted through the cable from electromagnetic interference, which is common in data centers, industrial environments, offices and other environments where there is a large amount of computer technology, electrical equipment or electronic equipment.<\/p><p>EMI is generated by external sources and affects circuits through electrostatic coupling, conduction, or electromagnetic induction. EMI interference can degrade the performance of a circuit or even cause it to stop functioning completely. These effects can range from increased error rates to complete data loss as long as a data path exists. Both natural and artificial (man-made) sources can produce variable currents and voltages that cause EMI. Vehicle ignitions and mobile phones are prime examples of artificially sourced EMI. Natural sources of EMI include electrical storms and the sun. EMI commonly disrupts AM radios, televisions, and mobile phones.<\/p><p>The shield of a shielded cable reduces the volume and intensity of electrical noise, reducing its effect on signals and transmissions, while also reducing electromagnetic emissions.<\/p><p><\/p>","protected":false},"excerpt":{"rendered":"<p>Shielded cable is a cable that contains an insulated conductor surrounded by a standard conductive shield.
