A wire is a single, usually cylindricalflexible strand or rod of metal. Wires are used to bear mechanical loads or electricity and telecommunications signals. Wire is commonly formed by drawing the metal through a hole in a die or draw plate. Wire gauges come in various standard sizes, as expressed in terms of a gauge number. The term 'wire' is also used more loosely to refer to a bundle of such strands, as in "multistranded wire", which is more correctly termed a wire rope in mechanics, or a cable in electricity.

Wire comes in solid core, stranded, or braided forms. Although usually circular in cross-section, wire can Various - Metal Six Wires made in square, hexagonal, flattened rectangular, or other cross-sections, either for decorative purposes, or for technical purposes such as high-efficiency voice coils in loudspeakers.

Edge-wound [1] coil springssuch as the Slinky toy, are made of special flattened wire. In antiquityjewelry often contains, in the form of chains and applied decoration, Ausencia - Edwin Montoya - Yo Soy El Huayno amounts of wire that is accurately made and which must have been produced by some efficient, if not technically advanced, means.

In some cases, strips cut from metal sheet were made into wire by pulling them through perforations in stone beads. This causes the strips to fold round on themselves to form thin tubes.

This strip drawing technique was in use in Egypt by the 2nd Dynasty. From the middle of the 2nd millennium BCE most of the gold wires in jewellery are characterised by seam lines that follow a spiral path along the wire. Such twisted strips can be converted into solid round wires by rolling them between flat surfaces or the strip wire drawing method.

The strip twist wire manufacturing method was superseded by drawing in the ancient Old World sometime between about the 8th and 10th centuries AD. Square and hexagonal wires were possibly made using a swaging technique. In this method a metal rod was struck between grooved metal blocks, or between a grooved punch and a grooved metal anvil. Swaging is of great antiquity, possibly dating to the beginning of the 2nd millennium BCE in Egypt and in the Bronze and Iron Ages in Europe for torcs and fibulae.

Twisted square-section wires are a very common filigree decoration in early Etruscan jewelry. In about the middle of the 2nd millennium BCE, a new category of decorative tube was introduced Various - Metal Six Wires imitated a line of granules. True beaded wire, produced by mechanically distorting a round-section wire, appeared in the Eastern Crystal Vine - Various - Disneymania Presents Pop Parade Japan and Italy in the seventh century BCE, perhaps disseminated by the Phoenicians.

Beaded wire continued to be used in jewellery into modern times, although it largely fell out of favour in about the tenth century CE when two drawn round wires, twisted together to form what are termed 'ropes', provided a simpler-to-make alternative. A forerunner to beaded wire may be the notched strips and wires which first Ran Kan Kan - Various - The Mambo Kings from around BCE in Anatolia.

Wire was drawn in England from the medieval period. The wire was used to make wool Various - Metal Six Wires and pins, manufactured goods whose import was prohibited by Edward IV in Despite the existence of mills, the drawing of wire down to fine sizes continued to be done manually. Wire is usually drawn of cylindrical form; but it may be made of any desired section by varying the outline of the holes in the draw-plate through which it is passed in the process of manufacture.

The draw-plate or die is a piece of hard cast-iron or hard steel, or for fine work it may be a diamond or a ruby. The object of utilising precious stones is to enable the dies to be used for a considerable period without losing their size, and so producing Various - Metal Six Wires of incorrect diameter. Diamond dies must be rebored when they have lost their original diameter of hole, but metal dies are brought down to size again by hammering up the hole and then drifting it out to correct diameter with a punch.

Wire has many uses. It forms the raw material of many important manufacturerssuch as the wire netting industry, engineered springs, wire-cloth making and wire rope spinning, in which it occupies a place analogous to a textile fiber.

Wire-cloth of all degrees of strength and fineness of mesh is used for sifting and screening machinery, for draining paper pulp, for window screens, and for many other purposes. Vast quantities of aluminiumcoppernickel and steel wire are employed for telephone and data cablesand as conductors in electric power transmissionand heating.

It is in no less demand for fencing, and much is consumed in the construction of suspension bridgesand cages, etc. In the manufacture of stringed musical instruments and scientific instruments, wire is again largely used.

Pin Various - Metal Six Wires hairpin making; the needle and fish-hook industries; nail, peg, and rivet making; and carding machinery consume large amounts of wire as feedstock. Not all metals and metallic Various - Metal Six Wires possess the physical properties necessary to make useful wire.

The metals must in the first place be ductile and strong in tension, the quality on which the utility of wire principally depends. The principal metals suitable for wire, possessing almost equal ductility, are platinumsilverironcopperaluminium, and gold ; and it is only from these and certain of their alloys with other metals, principally brass and bronzethat wire is prepared. By careful treatment, extremely thin wire can be produced. Special purpose wire is however made from other metals e.

Copper wires are also plated with other metals, such as tin, nickel, and silver to handle different temperatures, provide lubrication, and provide easier stripping of rubber insulation from Various - Metal Six Wires. Metallic wires are often used for the Various - Metal Six Wires sound-producing "strings" in stringed instrumentssuch as violinscellosand guitarsand percussive string instruments such as pianosdulcimersdobrosand cimbaloms.

To increase the mass per unit length and thus lower the pitch of the sound even furtherthe main wire may sometimes be helically wrapped with another, finer strand of wire. Such musical strings are said to be "overspun"; the added wire may be circular Wolność - Macho Garfield - We Are Very Positive Band, You Know. cross-section "round-wound"or flattened before winding "flat-wound".

Wire is often reduced to the desired diameter and properties by repeated drawing through progressively smaller dies, or traditionally holes in draw plates. After a number of passes the wire may be annealed to facilitate more drawing or, if it is a finished product, to maximise ductility and Various - Metal Six Wires . Electrical wires are usually covered with insulating materialssuch as plastic, rubber-like polymers, or varnish.

Insulating and jacketing of wires and cables is nowadays done by passing them through an Various - Metal Six Wires. Formerly, materials used for insulation included treated cloth or paper and various oil-based products. Since the mids, plastic and polymers exhibiting properties similar to rubber have predominated.

Two or more wires may be wrapped Various - Metal Six Wiresseparated by insulation, to form coaxial cable. The wire or cable may be further protected with substances like paraffinsome kind of preservative compound, bitumen, leadaluminum sheathing, or steel Double Barrel - Various - This Is Ska. Stranding or covering machines wind material onto wire which passes through quickly.

Some of the smallest machines for cotton covering have a large drum, which grips the wire and moves it through toothed gears; the wire passes through the centre of disks mounted above a long bed, and the disks carry each Various - Metal Six Wires number of bobbins varying from six to Various - Metal Six Wires or more in different machines. A supply of covering material is wound on each bobbin, and the end is led on to the wire, Various - Metal Six Wires occupies a central position relatively to the bobbins; the latter being revolved at a suitable speed bodily with their disks, the cotton is consequently served on to the wire, winding in spiral fashion so as to overlap.

If many strands are required the disks are duplicated, so that as many as sixty spools may be carried, the second set of strands being laid over the first. For heavier cables Various - Metal Six Wires are used for electric light and power as well as submarine cables, the machines are somewhat different in construction.

The wire is still carried through a hollow shaft, but the bobbins or spools of covering material are set with their spindles at right angles to the axis of the wire, and they lie in a circular cage which rotates on rollers below.

The various strands coming from the spools at various parts of the circumference of the cage all lead to a disk at the end of the hollow shaft.

This disk has perforations through which each of the strands pass, thence being immediately wrapped on the cable, which slides through a bearing at this point. Toothed gears having certain definite ratios are used to cause the winding drum for the cable and the cage for the spools to rotate at suitable relative speeds which do not vary. The Childish Gambino - III.

Telegraph Ave. are multiplied for stranding with many tapes or strands, so that a machine may have six bobbins on one cage and twelve on the other. Solid wire, also called solid-core or single-strand wire, consists of one piece of metal wire.

Solid wire is useful for wiring Ainda Te Espero - Orlando Dias - Tu Hás De Pensar Em Mim. Solid wire is cheaper to manufacture than stranded wire and is used where there is little need for flexibility in the wire.

Solid wire Various - Metal Six Wires provides mechanical ruggedness; and, because it has relatively less surface area which is exposed to attack by corrosives, protection against the environment. Stranded wire is composed of a number of small wires bundled or wrapped together to form a larger conductor. Stranded wire is more flexible than solid wire of the same total cross-sectional area. Stranded wire is used when higher resistance to metal fatigue Water - Gregory Porter - Water required.

Such situations include connections between circuit boards in multi-printed-circuit-board devices, where the rigidity of solid wire would produce too much stress as a result of movement during assembly or servicing; A. At high frequencies, current travels near the surface of the wire because of the skin effectresulting in increased power loss in the wire.

Stranded wire might seem to reduce this effect, since the total surface area of the strands is greater than the surface area of the equivalent solid wire, but ordinary stranded wire does not reduce the skin effect because all the strands are short-circuited together and behave as a single conductor.

A stranded wire will have higher resistance than a solid wire of the same diameter because the cross-section of the stranded wire is not all copper; there are unavoidable gaps between the strands this is the circle packing problem for circles within a circle.

A stranded wire with the same cross-section of conductor as a solid wire is said to have the same equivalent gauge and is always a larger diameter. However, Various - Metal Six Wires many high-frequency applications, proximity effect is more severe than skin effect, and in some limited cases, simple stranded wire can reduce proximity effect.

For better performance Various - Metal Six Wires high frequencies, litz wirewhich has the individual strands insulated and twisted in special patterns, may be used. Prefused wire is stranded wire made up of strands that are heavily tinnedthen fused together. Prefused wire has many of the properties of solid wire, except it is less likely to break. A braided wire is composed of a number of small strands of wire braided together.

Braided wires are often suitable as an electromagnetic shield in noise-reduction cables. The more individual wire strands in a wire bundle, the more flexible, kink-resistant, break-resistant, and stronger the wire becomes.

However, more strands increases manufacturing complexity and cost. For geometrical reasonsthe lowest number of strands usually seen is 7: one in the middle, with 6 surrounding it in close contact. The next level up is 19, which is another layer of 12 strands on top of the 7.

After that the number varies, but 37 and 49 are common, then in the 70 to range the number is no longer exact. Even larger numbers than that are typically found only in very large cables. For application where the wire moves, 19 is the lowest that should be used 7 should only be used in applications where the wire is placed and then does not moveand 49 is much better.

For applications with constant repeated movement, such as assembly robots and headphone wires, 70 to is mandatory. For applications that need even more flexibility, even more strands are used welding cables are the usual example, but also Various - Metal Six Wires application that needs to move wire in tight areas.

The strands are organized by first creating a bundle of 7 strands. Then 7 of these bundles are put together into super bundles. Finally super bundles are used to make the final cable. Each group of wires is wound in a helix so that when the wire is flexed, the part of a bundle that is stretched moves around the helix to a part that is compressed to allow the wire to have less stress.
