Shielded multi-conductor cable is a cable with multiple conductors and a metallic or nonmetallic shield placed over the cable core.
Shielded multi-conductor cable is a construction that combines several conductors with a shield placed over the entire cable core. The shield, which may be metallic, such as braid or foil, or a nonmetallic semiconductive material, surrounds the group of conductors to protect them collectively from electrostatic and electromagnetic interference. This allows a cable carrying multiple circuits to reject interference as a unit.
By shielding the whole core, this construction protects all of the conductors at once, which is efficient where many circuits must be isolated from external interference. Individual conductors or pairs within the cable may also be shielded for additional isolation, depending on the design.
In commercial and industrial cable, shielded multi-conductor cable serves control, audio, instrumentation, and communication applications requiring multiple circuits with interference protection. Recognizing the construction helps in understanding how cable protects grouped conductors.
Because shielding the whole core protects all of the conductors at once, the construction is efficient where many circuits must be isolated from external interference, and individual conductors or pairs within the cable may also be shielded for additional isolation depending on the design.
Recognizing how an overall shield protects grouped conductors helps illustrate how cable carrying multiple circuits rejects interference as a unit in control, audio, and communication systems.
At Windy City Wire, the focus on shielded low-voltage cable includes multi-conductor constructions with overall shields. Supplying cable that shields grouped conductors helps keep signals clean in the demanding environments of commercial and industrial systems.
