Difference Between Cable and Wire

Cables and wires are the most frequently used terms in electronics, telecommunications, and electrical appliances. We can say that wires are the inner component (conductors) used in the cables that are insulated inner as well as from the outer side.

The conductors are the materials commonly used in making cables and wires, strong metals like copper and aluminium as they are good conductors of electricity are preferred.

Cable vs Wire

The main difference between cable and wire is that cable has a bunch of wire conductors into it whereas wire on the other hand has a single conductor. A cable is made of multiple conductors and they are individually insulated while a wire is made of a single conductor and is not usually insulated. Cables can be preferred for long-distance telecommunication whereas wires for short distances.

Cable vs Wire

Cables are formed by many wires twisted around each other forming a single layer. Cables have an internal and lateral sheath which is made for safety reasons.

Mainly there are four types of cables: twisted pair cable, coaxial cable, multi-conductor cable, and fibre-optic cable. Cables are mostly used in our day-to-day use like cable tv, telecommunication purposes, theatres, studios, etc.

Wires are formed by a single conductor (copper or aluminium). They are coated with a thin layer of polyvinyl chloride which is a synthetic plastic polymer made by a process called polymerization.

There are mainly two types of wires which is solid and stranded. Solid wires are composed of a single thin stranded conductor which is stiff and has the bendable ability.

Stranded wires are composed of many thin stranded conductors that are twisted to form a single case.

What is Cable?

Cables are multiple stranded filaments of wire twisted together to form a single cable wire. It is insulated from both sides internally and externally as well.

There are four types of cables, each type of cable has a unique mechanism according to its purpose of use. Types of cables are as follows:

  1. Twisted pair cable: As the name includes, a pair (two) cables are twisted together to form a single cable.
  2. Coaxial cable is formed by a solid conductor internally and an outer layer with foil. Cable one is used in television media, radios, and other broadcast media.
  3. Multi-conductor cable: The cables are joined altogether to form a multi-conductor cable wherein it is used for the transmission of information.
  4. Optic-fiber cable: These are the cables made of fibres to replace metallic conductors because their bandwidth is larger than the normal cables.

Cables are used to transmit electrical impulses. These are generally made up of two or more wires connected. For any conceivable use, there is a vast array of cables available. Cables are commonly used in the transmission of power, electrical appliances/devices, communication purposes, etc. They are widely used in the transmission of signals to long distances, so they can be seen in television and radio transmissions.

What is Wire?

As previously stated, a wire is made of a single conductor or a collection of conductor filaments that are wrapped around each other in an insulation case to avoid undesired connections.

Wires are generally used for the transportation of telecommunications and electrical impulses.

Wires are divided into solid and stranded types. Solid wires are made of a long single conductor whereas stranded wires are made of two or more strands of single conductor twisted around each other.

Solid wires are generally preferred for higher frequencies due to their low resistivity, on the other hand, stranded wires last for a longer duration and are flexible.

As stranded wires are a group of two or more strands so they have a larger cross-sectional area compared to solid wires.

The diameter of a wire is used to determine its length. A gauge number will be assigned to the wire based on its diameter. The higher the gauge number will result in a thinner wire. The gauge number used in household appliances and devices is 10 and 20.

Big wires are used for industrial practices and should not be used for household appliances as they will damage the fuse by carrying more current into it.

Main Differences Between Cable and Wire

  1. Wires have a single conductor strand or a single conductor group of strands twisted around each other whereas cables are a group of conductors twisted around one another forming a single strand.
  2. Cables are safer than wires because they are insulated by both sides.
  3. In simpler words, we can say that wires are visible whereas cables are not visible due to their insulation.
  4. Cables have a higher strength capacity than wires. But they are more costly compared to the wires.
  5. Cables are used for telecommunication transmissions and carrying electrical impulses. Wires are used in day-to-day household chores to supply electricity (lights, ceiling fans, ACs, etc) and telecommunication signals.
  6. Cables have a longer shelf-life than wires, it is due to the insulation in the cables.
Difference Between Cable and Wire


Although the terms wires and cables are often used one for another. One way to tell them apart is to remember that cables are made up of wires. Wires also have a sufficiently broad range of applications.

The distinction between “wires” and “cables” is arbitrary. Care should be taken while using cable and wire to avoid any hazardous situation.

Materials utilized in electricity, telecommunication, and similar transmission applications are referred to as wire and cable.

Wire and cable essentially incorporate uncovered wires, electromagnetic wires, and protected wires for electrical machines, power cables, correspondence cables, and optical cables.

Cables are made out of various strands of wire used to associate circuits, electrical machines, and so forth.
