Types of electrical cables: a quick guide
Electrical cables attached to the walls, in different colors and different sizes, are part of the current dynamics on which we build our lives. Directly or indirectly, we all use them for endless tasks without realizing their importance and the different types of electrical cables that outlet.
What is electrical cable?
We call electrical cable an item made of different compounds with the aim or purpose of conducting electricity or passing electrons. The transmitted energy passes through the body of the cable to travel from one end to the other.
Electrical cable parts and components
For the electrical cable to function properly, different elements are needed. Each of these components performs a unique function. To ensure the passage of electrical current.
Electrical connector
It is perhaps the most important component of an electrical cable since electricity is transmitted through it . They can be made of different materials such as copper, aluminum and even gold. It is made up of one or more conducting threads.
isolation
It is the element responsible for covering or protecting the conductive element . It is made of different materials such as plastic or polymer, and it also performs the function of ensuring the passage of electric current and insulating the interior to prevent accidents.
Metal protection
Some cables include a pair of metal shields. The first one, called the screen, serves to protect the interior from outside interference, and at the same time, the second one, known as the shield, protects the interior from bumps, bites or other elements .
Coverage
The roof has the primary task of protecting the cable inside from external factors, and is generally made of polymeric material according to the insulation material.
Types of electrical conductors
Conductors are the soul of any cable, and like other elements in this field, there are many types of electrical conductors tasked with multiple tasks. Become an expert on this topic and everything related to electricity. Study the Electrical Installation Diploma and train yourself in a short time.
Bare wire connector
It is a single conductive wire or strand that does not have any coating on the wire. It is often used for grounding.
Insulated wire connector
It consists of a single bare wire covered with an insulator in order to avoid contact with the outside. Its use is very common in all types of electrical installations.
Flexible cable connector
This type has many plastic-coated connectors . It is made up of a variety of threads, making it more flexible and easy to use in all types of combinations.
Cord connector
A cord connector consists of different conductors of flexible cables insulated from each other, and laminated to form a single cable.
Types of electrical cables
Currently, no type of electrical or technological connection can function without the presence of different types of electrical cables
unipolar
This consists of a single conductive thread responsible for transmitting electrical current. They are usually very simple and common in different connections.
Multipolar
These consist of two or more conductive strands previously covered by an insulator. Due to the number of threads, it does not have much flexibility.
coaxial
Is it a type of cable used for television signals ? It consists of a single thread or wire, insulation, metal mesh, and coating.
braided
These cables are made of two or more cables intertwined within the same housing . An obvious example of this is UTP cables, which are used in computer systems such as Internet connections, security cameras, etc.
Duplex
It consists of two parallel cables that are used to transmit electrical power in homes and small places. It is also often called double wire.
From the tape
It is a series of wires placed side by side . This feature gives them a flat appearance that favors computing functionality.
biaxial
It has similar characteristics to coaxial cable, with the only difference being that it has two wires instead of one.
Measurement, measurements and uses of electrical cables
Electrical Wire Gauges It is one of many characteristics that determine the function of each. This factor describes the diameter of conductors and is taken as a reference to the American wire gauge or system for assigning a value.
Meaning of colors in electrical cables
Cable colors do not have a decorative or eye-catching aspect, because these colors have a specific and important reason to ensure the passage of electrical current.
Greens and yellows
These are the ground wires . They are responsible for going from the site ground to the home's electrical panel.
blue
It is a neutral wire that restores current favoring the correct passage of electrical energy.
Brown and black
The phase wires into which electrical energy enters. This can range from 220 to 230 volts and can only be handled by professionals.
Now you'll never look at cable the same way again. Don't forget that they are an essential part of all types of installation and are essential everywhere.
