Types of Wire - A Thomas Buying Guide

The terms wire and cable are often used as synonyms, but they actually have two different meanings. A wire is a single flexible strand of metal. A cable is two or more wires or other conductors grouped with sheathing or a jacket around them. In industry, wire is used to support loads or to carry electricity and telecommunication signals. Several strands of wire twisted together is referred to as wire rope. Wire rope is generally used for lifting and hoisting loads.

This article looks at the different types of wire used in electrical wiring, including wire harnesses , and telecommunications. Solid wire , also known as solid-core or single-strand wire, is made up of one piece of metal wire, usually surrounded by protective sheathing.

It is often used for circuit breadboard wiring. Its manufacture is less expensive than stranded wire. Solid wire is less susceptible to corrosion because it has less surface area exposed to the environment. It is used when less flexible wire is needed, such as building infrastructures, vehicle controls, and outdoor applications.

This breakage protects the other electrical devices from the short circuit current. Electric fuse wire is a solid wire made of an alloy with a low melting point. These tight coils are used for applications such as inductors, transformers, motors, electromagnets, and speakers. Stranded wire consists of multiple small wires bundled or wrapped together.

It is used for circuit board connections in multi-printed-circuit-board devices because the rigidity of solid wire would cause too much stress during assembly or servicing. It is comprised of many thin wire strands, individually insulated and twisted together, often involving several levels. Multiple tinsel wires are usually jacketed with an insulating layer to form one conductor.

Several conductors form a cord in either a round profile or a flat cable. Braided wire is composed of multiple small strands of wire that are braided together. Like stranded wires, braided wires are better conductors than solid wires. Braided wires are often used as an electromagnetic shield in noise-reduction cables.

An electrical cable is an assembly of one or more wires running side by side or bundled, which is used to carry electric current. A cable assembly is the composition of one or more electrical cables and their corresponding connectors. Cable assemblies can also take the form of a cable tree or cable harness , used to connect many terminals together. The term cable originally referred to a nautical line of specific length where multiple ropes are combined to produce a strong thick line that was used to anchor large ships. As electric technology developed, people changed from using bare copper wire to using groupings of wires and various sheathing and shackling methods that resembled the mechanical cabling so the term was adopted for electrical wiring. In the 19th century and early 20th century, electrical cable was often insulated using cloth, rubber or paper. Plastic materials are generally used today, except for high-reliability power cables.

Electrical Cable Types, Sizes, and Installation

More often than not, the terms wire and cable are used to describe the same thing, but they are actually quite different. Wire is a single electrical conductor, whereas a cable is a group of wires swathed in sheathing. The term cable originally referred to a nautical line of multiple ropes used to anchor ships, and in an electrical context, cables like wires are used to carry electrical currents.

These wires are either made of solid or stranded. Most wires are round although square and rectangular forms are also used in specific applications. These wires are manufactured with or without insulation depending upon the application. The heat developed varies according to the square of the current in amperes. They should not be allowed to reach a temperature that might cause a fire. Wire Sizes - Sizes of wires are specified in circular mil cmil which is the cross-sectional area of any round wire. These gauges are different from those used for steel wires or for non-electrical purposes like fence wire.

How to evaluate the number of electrical circuits in an older home. Photo guide to types of old building electrical wires. In this article series we list common old building electrical wiring system safety concerns and we illustrate types of old electrical wires and devices. This article series answers basic questions about assessing and repairing the electrical service, capacity, wiring type, condition, and safety in older homes. With the increase of electric lighting which today is used only to a very limited extent as compared with its inevitable future use and the multiplication of wires, these dangers which exist now in a thousand different parts of the city will be manifolded many times.

Фонтейн кивнул. Иерархия допуска в банк данных была тщательно регламентирована; лица с допуском могли войти через Интернет.

Он вечно навязывал что-то коллегам, например морковный сок, и убеждал их, что нет ничего важнее безукоризненного состояния кишечника. Хейл поставил масло на место и направился к своему компьютеру, располагавшемуся прямо напротив рабочего места Сьюзан. Даже за широким кольцом терминалов она почувствовала резкий запах одеколона и поморщилась.
