Cable type is named according to material and characteristics, Let VGCABLE talk about What are different types of cables? types of cables wiki & all types of cables.
1.What are different types of cables?Coaxial cable: used for radio frequency signals, for example in cable television distribution systems.
Communications cable: is a cable laid on the sea bed between land-based stations to carry telecommunication signals across stretches of ocean and sea.
Direct-buried cable: is a kind of communications or transmissions electrical cable which is especially designed to be buried under the ground without any kind of extra covering, sheathing, or piping to protect it.
Flexible cables: are electrical cables specially designed to cope with the tight bending radii and physical stress associated with moving applications, such as inside cable carriers.
Heliax cable: is part of Allied Wire and Cable’s extensive stock of Coaxial Cable. This selection of Coaxial Cables is designed for signal transfers in am/fm radio, UHF/VHS TV, and other communication systems.
Non-metallic sheathed cable (or nonmetallic building wire, NM, NM-B)
Metallic sheathed cable (or armored cable, AC, or BX)
Multicore cable (consist of more than one wire and is covered by cable jacket)
Paired cable – Composed of two individually insulated conductors that are usually used in DC or low-frequency AC applications
Portable cord – Flexible cable for AC power in portable applications
Ribbon cable – Useful when many wires are required. This type of cable can easily flex, and It is designed to handle low-level voltages.
Shielded cable – Used for sensitive electronic circuits or to provide protection in high-voltage applications.
Single cable (from time to time this name is used for wire)
Twin-lead – This type of cable is a flat two-wire line. It is commonly called a 300 Ω line because the line has an impedance of 300 Ω. It is often used as a transmission line between an antenna and a receiver (e.g., TV and radio). These cables are stranded to lower skin effects.
Twisted pair – Consists of two interwound insulated wires. It resembles a paired cable, except that the paired wires are twisted
2.Types of cables used in networkingThe following sections discuss the types of cables used in networks and other related topics.

Unshielded Twisted Pair (UTP) Cable
Twisted pair cabling comes in two varieties: shielded and unshielded. Unshielded twisted pair (UTP) is the most popular and is generally the best option for school networks (See fig. 1).
3.All types of cablesTypes of Wires – There are mainly 5 types of wire: .
Triplex Wires : Triplex wires are usually used in single-phase service drop conductors, between the power pole and weather heads. They are composed of two insulated aluminum wires wrapped with a third bare wire which is used as a common neutral. The neutral is usually of a smaller gauge and grounded at both the electric meter and the transformer.
Main Feeder Wires : Main power feeder wires are the wires that connect the service weather head to the house. They’re made with stranded or solid THHN wire and the cable installed is 25% more than the load required.
Panel Feed Wires : Panel feed cables are generally black insulated THHN wire. These are used to power the main junction box and the circuit breaker panels. Just like main power feeder wires, the cables should be rated for 25% more than the actual load.
Non-Metallic Sheathed Wires : Non-metallic sheath wire, or Romex, is used in most homes and has 2-3 conductors, each with plastic insulation, and a bare ground wire. The individual wires are covered with another layer of non-metallic sheathing. Since it’s relatively cheaper and available in ratings for 15, 20 and 20 amps, this type is preferred for in-house wiring.
Single Strand Wires : Single strand wire also uses THHN wire, though there are other variants. Each wire is separate and multiple wires can be drawn together through a pipe easily. Single strand wires are the most popular choice for layouts that use pipes to contain wires.
Types of Electrical Cables – There are more than 20 different types of cables available today, designed for applications ranging from transmission to heavy industrial use. Some of the most commonly-used ones include:.
Non-Metallic Sheathed Cable : These cables are also known as non-metallic building wire or NM cables. They feature a flexible plastic jacket with two to four wires (TECK cables are covered with thermoplastic insulation) and a bare wire for grounding. Special varieties of this cable are used for underground or outdoor use, but NM-B and NM-C non-metallic sheathed cables are the most common form of indoor residential cabling.
Underground Feeder Cable : These cables are quite similar to NM cables, but instead of each wire being individually wrapped in thermoplastic, wires are grouped together and embedded in the flexible material. Available in a variety of gauge sizes, UF cables are often used for outdoor lighting and in-ground applications. Their high water-resistance makes them ideal for damp areas like gardens as well as open-to-air lamps, pumps, etc.
Metallic Sheathed Cable : Also known as armored or BX cables, metal-sheathed cables are often used to supply mains electricity or for large appliances. They feature three plain stranded copper wires (one wire for the current, one grounding wire and one neutral wire) that are insulated with cross-linked polyethylene, PVC bedding and a black PVC sheathing. BX cables with steel wire sheathing are often used for outdoor applications and high-stress installations.
Multi-Conductor Cable : This is a cable type that is commonly used in homes, since it is simple to use and well-insulated. Multi-conductor or multi-core (MC) cables feature more than one conductor, each of which is insulated individually. In addition, an outer insulation layer is added for extra security. Different varieties are used in industries, like the audio multicore ‘snake cable’ used in the music industry.
Coaxial Cable : A coaxial (sometimes heliax) cable features a tubular insulating layer that protects an inner conductor which is further surrounded by a tubular conducting shield, and might also feature an outer sheath for extra insulation. Called ‘coaxial’ since the two inner shields share the same geometric axis, these cables are normally used for carrying television signals and connecting video equipment.
Unshielded Twisted Pair Cable : Like the name suggests, this type consists of two wires that are twisted together. The individual wires are not insulated, which makes this cable perfect for signal transmission and video applications. Since they are more affordable than coaxial or optical fiber cables, UTP cables are often used in telephones, security cameras and data networks. For indoor use, UTP cables with copper wires or solid copper cores are a popular choice, since they are flexible and can be easily bent for in-wall installation.
Ribbon Cable : Ribbon cables are often used in computers and peripherals, with various conducting wires that run parallel to each other on a flat plane, leading to a visual resemblance to flat ribbons. These cables are quite flexible and can only handle low voltage applications.
Direct-Buried Cable : Also known as DBCs, these cables are specially-designed coaxial or bundled fiber-optic cables, which do not require any added sheathing, insulation or piping before being buried underground. They feature a heavy metal core with many layers of banded metal sheathing, heavy rubber coverings, shock-absorbing gel and waterproof wrapped thread-fortified tape. High tolerance to temperature changes, moisture and other environmental factors makes them a popular choice for transmission or communication requirements.
Twin-Lead Cable : These are flat two-wire cables that are used for transmission between an antenna and receiver, like TV and radio.
Twinaxial Cable : This is a variant of coaxial cables, which features two inner conductors instead of one and is used for very-short-range high-speed signals.
Paired Cable : With two individually insulated conductors, this cable is normally used in DC or low-frequency AC applications.
Twisted Pair : This cable is similar to paired cables, but the inner insulated wires are twisted or intertwined.
