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.

Role Of Resistance And Resistivity In Different Types Of Wires

Electric wires form an important part of our lives. They play an important role in supplying electricity or electrical signals from the power generating unit to our homes. Wires are made up of different types of materials. The behavior of wires changes when the electricity is supplied to a longer distance than when they are used in a circuit of a device. You must have known about the multiconductor wires, shielded and unshielded wires. But today in this blog, we will discuss the resistance and their effects in various types of wires.

All the devices either work on AC or DC power. The circuits that work on AC power, face a lot of problems such as skin effect and proximity effects like-resistivity/impedance. Let’s understand what is resistance and its effects.

Resistance reduces the movement of electric charge through the wire. Moreover, it increases when the distance is high or the length of the wire is too long. So, the resistance depends on the type of the material of the wire. For example, in the copper wire, the resistance is very less. The reason is that copper is highly conductive wire.

The resistivity of the aluminum wire is very high compared to the copper wire. This is why copper wires are used to transmit the electricity from one place to another instead of using aluminum wires. In short, it is the loss of current while transmitting or supplying the electric charge.


But resistance is good in some cases. While transmitting the electricity the heat is produced and it results in loss of energy. However, in a tungsten or tantalum wire, this heat is used to make the wire glow and produce light, which is desired in some cases. Tungsten is used to make filaments because it has a very high melting point.

The wire can get very hot and glow brightly without melting. But wires made up of Tungsten are not efficient in power transmission since most of the energy is lost in the form of heat and light.
