Do you know what is the material on which it is not possible to make an electrical installation? If you answered the electrical conductor, you were right! But do you even know what electrical conductors are? And electrical insulation? Do you know how they work or what their types are? If not, this article is for you! If so, this article is also for you because we will explain what electrical and insulating conductors are, how a conductor works and let us talk about the types of electrical conductors, come on guys!
Electrical Conductors: What are they?
An electrical conductor is a material that offers low electrical resistance and makes it easy to pass electrical current through it.
In a free electron structure possess a very weak link with the atomic nucleus, which makes it much easier for the electrons to scatter and move disorderly By applying a potential difference ( voltage ) the movement of electrons is driven and orderly, the which ends up generating an electric current that will move along the conductor.
What are drivers?

Types of Conductors
Despite what many think, drivers are not only solid! Electric conductive materials have three types, solid conductors, liquid conductors and gaseous conductors.
Also known as metallic conductors, solid conductors have free electrons in their structures, and because these electrons do not have a strong connection with the nucleus, the result is a fast energy conduction because metals donate electrons easily.
Also known as third-class or third-class conductors, gaseous conductors are charged with positive ions that are technically known as cations, and negative ions that are technically known as anions. Energy production occurs when cations and anions collide.
Also known as electrolytic conductors, liquid conductors generate electrical current when the positive ions that are technically known as cations and the negative ions that are technically known as anions travel in discordant directions, that is, they create an ionic dissolution in this movement.
Examples of Electrical Conductors
The following elements and materials can be described as conductors below:
In gaseous state: Any ionized gases.
In solid state: Copper, aluminum, gold, silver, magnesium, mercury (although in most cases it is in a liquid state, it is a metal), lead, lithium and others.
In liquid state: Sodium, potassium, calcium, and others. (They are usually dissolved in water).
What is thermal insulation and electrical insulation?
Insulating Material What is it?
See what are insulating materials!
Electrical insulators are materials that offer high resistance and hinder the passage of electrical current. Due to its structure with electrons strongly linked to the atomic nucleus, the number of free electrons in the insulating material is very low and the space for electron movement is very small.
Electrical insulators are widely used to prevent current from flowing or to prevent leakage of electrical current in a conductive cable.
Thermal insulators are materials that offer high resistance to the passage of temperature. As in their structure, electrons are strongly linked to the atomic nucleus, they have no way to move and collide with others to transmit a temperature.
Thermal insulators are widely used to produce bottles or thermal objects, but they are also used in conductive cables, as they increase the resistance to the heat generated by the current flow.

Examples of insulating materials
Examples of thermal and electrical insulators are the elements and materials below:
Electrical insulation: Ceramics, glass, rubber, plastic, oil, non-ionized gases, styrofoam, wood, acrylic, and others.
Thermal insulation: Wood, air, neoprene, styrofoam, glass wool, ceramics, earth, and others.
