Electrical cables attached to the walls, of different colors and sizes, are part of the current dynamics on which we build our lives. Directly or indirectly, we all use it for endless tasks without realizing its importance and the different  types of electrical cables  that outlet.

What is electrical cable?

We call electrical cable  an item made of various compounds with the purpose or goal of conducting electricity  or passing electrons. The transmitted energy passes through the body of the cable to be transmitted from one end to the other.

Electrical cable parts and components

In order for the electrical cable to function properly, various elements are needed. Each of these components performs a unique function.  to ensure the passage of electric current.

Electrical connector

It is perhaps the most important component of an electrical cable since  electricity is transmitted through it . It can be made of different materials such as copper, aluminum and even gold. It is made up of one or more conductive strands.

isolation

It is the component  responsible for covering or protecting the conductive component . It is made of various materials such as plastic or polymer, and it also performs the function of ensuring the passage of electric current and isolating the interior to prevent accidents.

metal protection

Some cables include a pair of metal shields. The first one is called the screen, and works 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 from the inside from external factors,  and is generally made of a polymeric material according to the insulation material.

Types of electrical connectors

Connectors are the soul of any cable, and like other items in the field, there are many  types of electrical connectors  tasked with multiple tasks. Become an expert on this topic and all things electrical. Study the electrical installation diploma and train yourself in no time.

bare wire connector

It is a single wire or conductor strand  that does not have any coating  of 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 is distinguished  by its many  plastic coated connectors. It is made up of a variety of yarns, which makes it more flexible and easy to use in all types of installations.

cord connector

A cord conductor consists of  various flexible cable conductors  insulated from each other, and sheathed to form one.

Types of electrical cables

Currently, no type of electrical or technological connection can function without the presence of various types of electrical cables

unipolar

These  consist of a single conductive thread  responsible for transmitting electric current. They are usually very simple and common in various 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 elasticity.

coaxial

Is it some kind of  cable used for TV signals ? It consists of a single strand or wire, insulation, metal mesh, and coating.

braided

These cables are made of two or more  cables interwoven within the same housing . An obvious example of this is UTP cables, which are used in computer systems such as Internet connections, security cameras, and others.

Duplex

It consists of two parallel cables  that are used to transmit electrical energy in homes and small places. It is also often called the double wire.

from the tape

It is  a series of wires placed side by side . This feature gives them a flat look 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 the many characteristics that determine the function of each of them. This factor describes the diameter of the conductors and is taken as a reference to an American wire gauge or system to designate a value.

Meaning of colors in electrical cables

The colors of the cables do not return to a decorative or eye-catching aspect, because these colors have a specific and important reason for ensuring the passage of electric current.

Greens and yellows

These are  the ground wires . They are responsible for the transition from the site floor to the home’s electrical panel.

blue

It is  a neutral wire that returns current  favoring the correct passage of electrical energy.

brown and black

The phase wires are  into which the electrical energy enters.  This can range from 220 to 230 volts and can only be handled by professionals.

Now you will 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.
