One application is when signal isolation is required. Twisted pair wire tends to self-shield for differential signals. This is because external interference induces equal currents in both conductors due to the symmetry of the twists. The differential input then cancels out the common-mode (equal on both wires) noise, allowing the desired differential signal to pass. One interesting example of this is UTP (CAT5, CAT6, etc.) cable used for ethernet cabling. If you strip the jacket off of a length of cable, you will notice (obviously) that the pairs are twisted. Look closely though, and you will notice that each pair is twisted with a different twist-per-inch than the other. If each pair had exactly the same twist, then the pairs cold 'line up' with each other, allowing crosstalk between the pairs (very bad). By varying the twist rate, crosstalk is minimized. In fact, the different twists are prime numbers, which means they never match up anywhere in the cable! Is that cool or what!

What are the advantages of ordinary twisted pair compared to the shielded ones?
Twisted pair wire is placed inside a thin metallic shielding, similar to aluminum foil, and is then enclosed in an outer plastic casing. The shielding provides further electrical isolation of the signal-carrying pair of wires. Shielded twisted pair wires are less susceptible to electrical interference caused by nearby equipment or wires and, in turn, are less likely to cause interference themselves. Because it is electrically "cleaner," shielded twisted pair wire can carry data at a faster speed than unshielded twisted pair wire can. The disadvantage of shielded twisted pair wire is that it is physically larger and more expensive than twisted pair wire, and it is more difficult to connect to a terminating block.

What is the advantages and disadvantages of twisted pair copper?
Shielded twisted pair wires are less susceptible to electrical interference caused by nearby equipment or wires and, in turn, are less likely to cause interference themselves.

Do steel wiredrawing plants make twisted wire?
Yes, steel wiredrawing plants can produce twisted wire by combining multiple strands of wire together. Twisted wire is commonly used in applications such as fencing, industrial machinery, and construction materials due to its increased strength and durability.
Why twisted pair wire is called twisted pair?
Twisted pair is the ordinary copper wire that connects home and many business computers to the telephone company. To reduce crosstalk or electromagnetic induction between pairs of wires, two insulated copper wires are twisted around each other. Each connection on twisted pair requires both wires. Since some telephone sets or desktop locations require multiple connections, twisted pair is sometimes installed in two or more pairs, all within a single cable. For some business locations, twisted pair is enclosed in a shield that functions as a ground. This is known as shielded twisted pair (STP). Ordinary wire to the home is unshielded twisted pair (UTP).Twisted pair is now frequently installed with two pairs to the home, with the extra pair making it possible for you to add another line (perhaps for modem use) when you need it.Twisted pair comes with each pair uniquely color coded when it is packaged in multiple pairs. Different uses such as analog, digital, and Ethernetrequire different pair multiples.Although twisted pair is often associated with home use, a higher grade of twisted pair is often used for horizontal wiring in LAN installations because it is less expensive thancoaxial cable.The wire you buy at a local hardware store for extensions from your phone or computer modem to a wall jack is not twisted pair. It is a side-by-side wire known as silver satin. The wall jack can have as many five kinds of hole arrangements or pinouts, depending on the kinds of wire the installation expects will be plugged in (for example, digital, analog, or LAN) . (That's why you may sometimes find when you carry your notebook computer to another location that the wall jack connections won't match your plug.)
Are twisted pair wire and coxial cable the same?
No. Coaxial cable is a single wire that has a thick coating around it. A common use of coaxial cable is for cable television. This is the cable that goes from the jack on the wall into your cable box. Twisted pair contains multiple cables which are split into pairs and twisted together. CAT5/CAT5e/CAT6 cable are all examples of twisted pair. There are a total of 8 wires inside. Every two wires are twisted together to form a pair. The purpose of the cables being twisted together is to reduce electrical interference between the wires.
