Different Types Of Cables

Types Of Cables Reviews & Guide

Introduction: Types of Electrical Cables

A cable can be defined as the grouping of multiple wires encased in a common sheathing and a  wire is a single electrical conductor. The widespread use of electricity is enabled because of the use of wires and cables. From households to telecom sectors, different types of cables are being used. The cables are differentiated based on their material and applications. 

The cables are distinguished from one another based on their construction and intended function. Identification of electric cables is crucial since it provides information on their length, number, and kind of insulation. The most crucial component of a cable’s identification is the plastic coating or insulation that surrounds the conducting wires.

Some of the labels or identifications that are regularly written on cables are THHN, THWN, THW, and XHHN. Below is a list of the labels’ respective letter meanings.

  • T – Thermoplastic insulation is a fire-resistant material.
  • H – Materials that are heat-resistant may withstand temperatures of up to 167 F.
  • HH stands for Highly Heat-Resistant and can withstand heat up to 194 F.
  • W – Wet works well in dry settings.
  • X: Insulation made of synthetic polymers that are flame-resistant.
  • N- Nylon-coated, oil- and gasoline-resistant.

Not all devices use a similar type of cabling. Having a knowledge of the different types of cables will assist you in having a better insight into what’s going on inside the electrical appliances around you or where and how your electricity reaches you.

Depending on the applications of electrical cables there are more than 20 different types of cables. Let’s take a closer look at them. But before that – composition of cables. 

Electrical cables are essential components of electrical systems, serving the purpose of transmitting electrical power or signals from one point to another. The composition of types of electrical cables can vary depending on their intended application, but they generally consist of several key components:

1. Communication Cable:

The type of cables used for the transmission of signal or in the other words, for communication purposes is called communication cables. They can be of three subtypes.

● Coaxial Cable :

Coaxial Cable

Coaxial cables are made of 4 layers forming the coaxial structure (i.e., having a common center or axis). The central layer is the conductor. The surrounding layer which is the second layer is the insulating plastic. These two layers are encased in a metallic sheath. The last layer is the outer insulating plastic. Amongst the different types of cables, coaxial cable is used to transmit high frequencies with very low noise interference (achieved by the presence of metallic sheath). It is used in cable television, satellite communications, and high-speed internet access.

Types Uses Cost

12. Ladder Line:

Ladder Line

Ladder line cables are important in wet conditions as sometimes wetness seeps inside the plastic covering the conductors. This will cause interference in the signal. To avoid such interference, slots like a window are cut into the plastic layer. The wire thus resulting will resemble a ladder-like structure. Hence, the name ladder line has been coined. The Cost and use of ladder line cable are as given below.

Uses Cost (approx.)
transmitter or receiver with RF antennas in TV and Radios etc. Rs.20

13. Underground Feeder (UF) Cable:

Underground Feeder (UF) Cable

14. Flexible Cables:

Flexible Cables

Flexible cables are yet another one amongst the different types of cables. It can withstand continuous bending in moving appliances. The flexibility is obtained by the usage of stranded conductors. Its uses and cost are as given below.

Uses Cost (approx.)
Used in CNC-based machines like milling machines, engraving, etc., pick and place machines Rs.50 – Rs.6000


The different types of cables also include power transmission cables seen in overhead transmission lines. There are 4 types as is mentioned below.

1. All Aluminum Conductor (AAC):

AAC is made from various strands of hard-drawn aluminum alloy. This alloy is 99 % pure with little iron, silicon, etc. It is highly conductive and resistant to corrosion.


Short-distance communication in stations

2. All Aluminum Alloy Conductor (AAAC):

The mechanical strength of the AAC cable is low so to increase it, an aluminum alloy is made with silicium and magnesium. It has an increased ratio of strength to weight while maintaining corrosion resistivity.

3. Aluminum Conductor Steel-Reinforced (ACSR) Cable:

ACSR is an improvement to AAAC’s lack of conductivity. There are inner strands made from galvanized steel which are surrounded by strands of pure aluminum conductors. The steel core increases the tensile strength of the cable while the aluminum provides good conductivity.


They are used in long-distance transmission lines as the strength of their steel core can be altered to meet the requirement.

4. Aluminum Conductor Aluminum-alloy Reinforced (ACAR):

ACAR is basically pure aluminum conductors that surround an aluminum core. The structure of ACAR is similar to ACSR with the exception that its core is made of aluminum alloy. It increases the overall conductivity (otherwise called ampacity) while maintaining the same tensile strength of ACSR.
