polyester<\/a>. In truth, merging these two metals helps to enhance cable strength.<\/p>\n\n\n\nYou can also call this shield cable type \u201ctape shielding.\u201d And it offers 100% EMI protection. As a result, no instance of EMI will penetrate any wire you wrap in foil or mylar shielding.<\/p>\n\n\n\n
However, the foil inside the cable is delicate, making such cables tricky to work with\u2013especially when using a connector. Regardless, tape shielding is ideal for noisy retail or office environments.<\/p>\n\n\n
Can You Use Multiple Shielding Layers?<\/h3>\n\n\n You can use multiple shielding layers for boisterous environments where each shielding type won\u2019t work individually. For such cases, you can combine braided and foil shields to create the ultimate cable shielding.<\/p>\n\n\n\n
In truth, both types are visible on some applications using multi-conductor cables. But sometimes, manufacturers may foil-shield individual pairs and braid (or foil-shield again) overall cables.<\/p>\n\n\n\n
Foil shielding individual pairs can reduce the chances of crosstalk between a cable\u2019s different pairs.<\/p>\n\n\n
Power Cable Shielding vs. Unshielded Cables: What are the Differences?<\/h2>\n\n\n True to their name, unshielded cables do not possess any shielding. Also, you can call them unshielded twisted pair cables (UTP), where manufacturers wrap individual wires in foil without adding extra protective layers.<\/p>\n\n\n\n
So, what are the differences between them and cable shielding? Let\u2019s take a look.<\/p>\n\n\n
Applications<\/h3>\n\n\n Shielded cables are the go-to option for noisy environments with high EMI chances and risks. Places like radio stations and airports are perfect instances of such environments.<\/p>\n\n\n\n
You can also use shielded cables in security systems, helping to avoid power and radio frequency interference. As a result, you\u2019ll enjoy reduced chances of false alarm triggering.<\/p>\n\n\n\n
Shielded cables are also effective for box-build applications with various components working closely together. In addition, they work in recording or public address systems, helping to create a balanced audio configuration.<\/p>\n\n\n\n
On the other hand, unshielded cables are perfect for applications that don\u2019t require their shielded variants. For example, home and office LANs are inexpensive, flexible, and lightweight unshielded cables that work for less-noise applications.<\/p>\n\n\n
Benefits<\/h3>\n\n\n As mentioned, shielded cables can help prevent annoying EMI effects on people and equipment, reducing the chances of crosstalk between wires. Also, shielding adds extra insulation, protecting the cable from environmental elements.<\/p>\n\n\n\n
As a result, shielded cables won\u2019t easily suffer from abrasion, spills, moisture, or scraps, making them perfect for industrial environments.<\/p>\n\n\n\n
In contrast, unshielded cables do not need grounding to operate. Hence, they help to save cost and installation time.<\/p>\n\n\n
Do You Ground Both Ends of a Shielded Power Cable?<\/h2>\n\n\n Shielded power cables are more effective when you surround them with conductive tunnels at ground potential. In other words, you should ground shielded power cables on both ends.<\/p>\n\n\n\n
Note: Grounding on only one end would transform the other into an antenna for some frequencies.<\/em><\/p>\n\n\nHow Do You Shield Electrical Cables?<\/h2>\n\n\n You can shield a power cable by surrounding the insulation or assembly with a conducting and grounded medium. This process restricts the dielectric field to inside the shield.<\/p>\n\n\n
Last Words<\/h2>\n\n\n Most times, the cable you need depends on your application requirements. Nevertheless, always opt for high-quality, shielded, or unshielded cables.<\/p>\n\n\n\n
Another thing to consider is your work environment. For example, shielded cables are the best for noisy locations like airports and radio stations. <\/p>\n\n\n\n
Also, some settings may require foil-shielded cables, while others may accept braided variants. And some may demand a mix of both shielded cable types.<\/p>\n\n\n\n
