10 Facts About Insulated wire

In electricity and telecommunications signals, a "Insulated wire" can refer to an electrical cable, which can contain a "solid core" of a single Insulated wire or separate strands in stranded or braided forms.

Usually cylindrical in geometry, Insulated wire can be 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.

In some cases, strips cut from metal sheet were made into Insulated wire by pulling them through perforations in stone beads.

True beaded Insulated wire, produced by mechanically distorting a round-section Insulated wire, appeared in the Eastern Mediterranean and Italy in the seventh century BCE, perhaps disseminated by the Phoenicians.

The Insulated wire was used to make wool cards and pins, manufactured goods whose import was prohibited by Edward IV in 1463.

The Insulated 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 Insulated wire, and they lie in a circular cage which rotates on rollers below.

Solid Insulated wire provides mechanical ruggedness; and, because it has relatively less surface area which is exposed to attack by corrosives, protection against the environment.

Prefused Insulated wire is stranded Insulated wire made up of strands that are heavily tinned, then fused together.

Prefused Insulated wire has many of the properties of solid Insulated wire, except it is less likely to break.

The principal metals suitable for Insulated wire, possessing almost equal ductility, are platinum, silver, iron, copper, aluminium, and gold; and it is only from these and certain of their alloys with other metals, principally brass and bronze, that Insulated wire is prepared.
