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.

Types of Electrical Wires and Cables

Electrical cable and wires are considered as a same thing. In fact they are quite different. A wire is made of a single electrical conductor while a cable is a group or bundle of multiple wires inside a common sheathing. Both of them are used for carrying electrical current. Nowadays due to the advancement in technology, almost everything is powered by electricity. Be it indoor or outdoor, we need supply of smooth, uninterrupted electricity which is achieved by using suitable type of wires and cables. Not only the electrical sector uses cables and wires for power transmission and distribution to our house and industries, the Telecom sector also relies on various types of cables for uninterrupted data transmission.

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. Whether indoors or outdoors, proper wire and cable installation is of paramount importance - ensuring a smooth electricity supply, as well as passing electrical inspections. Each wire and cable needs to be installed carefully, from the fuse box to the outlets, fixtures and appliances.

Cable is the medium through which information usually moves from one network device to another. There are several types of cable which are commonly used with LANs. In some cases, a network will utilize only one type of cable, other networks will use a variety of cable types. The type of cable chosen for a network is related to the network's topology, protocol, and size. Understanding the characteristics of different types of cable and how they relate to other aspects of a network is necessary for the development of a successful network. The following sections discuss the types of cables used in networks and other related topics.

An electric cable has the purpose of transporting electrical energy from one point to another. Depending on their final application, cables can have different configurations, always basing their design on national and international regulations. An electric cable is measured in volts and, depending on these, they are categorized into one group or another:. Flexible cables for wiring electric cabinets. These electric cables are especially suitable for domestic use, for installation in public places and for internal wiring of electrical cabinets, switch boxes and small electrical appliances. Energy cables for industrial facilities and public places. It is common to find power cables in applications for power transmission in all types of low voltage connections, for industrial use and for variable frequency drive VFD.


The National Electrical Code (NEC) and Local Building Codes regulate the manner of installation and the types of wires and cables for various electrical.


Tables of AWG wire sizes. The table below shows various data including both the resistance of the various wire gauges and the allowable current ampacity based on plastic insulation. The diameter information in the table applies to solid wires. Stranded wires are calculated by calculating the equivalent cross sectional copper area. Turns of wire is an upper limit for wire with no insulation.

Ему не нужно было напоминать, что произойдет, если три миллиона процессоров перегреются и воспламенятся. Коммандеру нужно было подняться к себе в кабинет и отключить ТРАНСТЕКСТ, пока никто за пределами шифровалки не заметил этой угрожающей ситуации и не отправил людей им на помощь. Стратмор бросил взгляд на лежавшего в беспамятстве Хейла, положил беретту на столик рядом со Сьюзан и крикнул, перекрывая вой сирены: - Я сейчас вернусь! - Исчезая через разбитое стекло стены Третьего узла, он громко повторил: - Найди ключ.

    An electrical cable is an assembly of one or more wires running side by side or bundled, which is used to carry electric current.

    When you're installing new wiring, for example, choosing the right wire or cable is half the battle.
