What is shielded cable?
Shielded cable is a cable that contains an insulated conductor surrounded by a standard conductive layer. 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.
Shielded cables are usually thicker and more rigid than unshielded cables. They also require more care when used. Shielded cables are most often found in industrial settings and installations where other equipment nearby may generate electromagnetic interference.
There are many types of cable shields available commercially, and the use depends on the application.

What is the purpose of shielded wire?
Shielded cables are used to protect data transmitted through the cable from EMI exposure, which is common in data centers, industrial settings, offices, and other environments where there is heavy use of computer technology, electrical equipment, or electronic equipment.
