Different Types of Electrical Cables/Wires

Wires are important and they are the only source through which electric charge is transmitted from one place to another. The wires are used across the world. Wires are available in different types. Generally, they are cylindrical, flexible strand or rod of metal. Selection of wires is a challenging task as there are different types of wires used in different industries. Below are some of the types that are used in industries as well as in our houses.

Non-Metallic Sheathed Cable- These are also known as non-metallic building wire or NM cables. The main feature of these type of cables is- they have a plastic jacket that covers two or more wires. These are commonly used for the underground or outdoor usage.

Underground Feeder Cable- These cables are quite similar to Non-Metallic sheathed cable, but in underground feeder cables, all the wires are grouped and wrapped in a flexible material. These are available in different varieties. They are often used for outdoor lighting and in-ground applications. They have high water-resistance that makes them ideal for moist areas like gardens as well as open-to-air lamps, pumps, etc.

Metallic Sheathed Cable- These types of wires are often used to supply electricity from the main manufacturing unit to the industries. Basically, they are required to run large appliances. This type of wire consist of three wires. One is for current, one is for the grounding wire and third one os a neutral wire. They are covered with the PVC sheathing and also known as PVC wires. They are used for outdoor applications and high-stress installations.


Coaxial wires- A coaxial cable has a tubular insulating layer which protects an inner conductor. In this the two inner shields share the same geometric axis, these cables are normally used for carrying television signals and connecting video equipment.

Ribbon Cable- They 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. Ribbon Cables are quite flexible and can control applications that require low voltage.
