Sheathed cabling normally contains 4 sets of wires (like normal Ethernet cable) with a covering of a plasticy - exterior material. Normally this is PVC but many newer types of cabling use other sheathing materials - especially for cabling designed for fire codes. Shielded cabling commonly includes a thin metal foil surrounding the wire pairs under the plastic sheath. This greatly increases the EMI resistance of the cable when it is terminated correctly. Many shielded cables also include an extra wire that "grounds out" the shielding foil. With terminators that include a metal body you can connect the extra, grounding wire to this terminator shield and ensure the highest amount of protection.
Shielded cable is recommended for areas with high levels of interference (such as industrial settings) which may cause signal degradation. For most common household uses, sheathed cable is perfectly appropriate.

What is the difference between beldan shielded and unshielded cable?
Shielded cable, when the shield is properly grounded, will minimize the amount of EM noise that reaches the shielded conductors.
What is the difference between sheathed and non-sheathed cable?
Cable sheath current is a current induced in the sheath by radio, magnetic or other interference, or a fault condition. The cable sheath should be grounded at one end so that this current flows to ground safely.
What are the colors of the conductors in nonmetallic sheathed cable for two wire cable?
The wire conductor colors in a non metallic sheathed cable are black, red, white, and a bare copper.
The use, installation, and construction specifications of nonmetallic-sheathed cable are covered within article?
NEC, Article 336 covers the use, installation and construction specifications for nonmetallic-sheathed cable. Nonmetallic-sheathed cable may be used for either exposed or concealed wiring.
What is the difference between shielding and screening effect?
when we use some metal wrap around a single pair it is called shield like STP ( shilelded twisted pair cable) , when all shielded pair are overall wrapped by some metal it is called screen for example S/STP that is screened shielded twisted pair cable ,
What is the difference between RG11 and RG213 cable?
RG-11/U is 75ohm and is usually triple/quad shielded and typically has a maximum attenuation of 3.65. RG-213/U is common form amateur radion and is 50 ohms and is single shielded with about a 5.95 attenuation.
What is the meaning of stp cable?
Shielded Twisted pair cable
What is pilc cable?
Paper Insulated Lead Sheathed Cable. Used for medium voltage levels.
Where in a vehicle would you find a shielded cable?
In various places - electrical wires and cables are shielded to stop wearing through, or getting wet, the hand brake cable is also shielded to prevent corrosion, was there a specific cable you wanted to know about ?
What is the difference between a shielded and an unshielded speaker cable?
The difference between a Microphone (shielded) cable and a normal speaker cable is that, When we use a microphone we use a balanced or shielded cable (with the three pins, XLR or cannon), not a normal two wire speaker cable. We use this because the single coming from the microphone is at mic level, below LINE level (less than 1 volt). The shield on the mic cable is connected into the mixer or amp. The shield wire (RF, Radio frequency interference) single its 'waves' are then flipped (reverse phase) to cancel the interference out, any excess interference is then taken to the earth wire. With out a shielded cable you would hear annoying interference eg. The typical phone beep (please turn phone off). Speaker cable does not need a shield because the signal coming into the speaker is above MIC level and RF interference can't get in (it isn't loud enough) so there is no RF interference and no need for a shield. Hope that has been a help!
Why there is no interference in twisted pair cable?
there is. shielded cable reduces the interference though
