Conheça 10 condutores e 10 isolantes elétricos

Meet 10 conductors and 10 electrical insulators

Geartech BR is an importer of films, polyester compounds and electrical insulators. Here on our blog, you can find some articles talking about conductors and electrical insulators.

In this particular article, we want to talk a little more about the two and give 10 examples of each. That is, 10 electrical conductors and 10 electrical insulators. Keep reading to learn more!

Do you know how to make a conductive or insulating material electrical? Quite simply, electrical conductors are materials that conduct electricity and electrical insulators are materials that do not conduct.

If a substance conducts electricity is determined by the ease with which electrons move through it, electrical conductivity depends on the electron’s movement, as protons and neutrons do not move. They are linked to other protons and neutrons in atomic nuclei.

See below for a list of the top 10 electrical conductors.


10 electrical conductors

The best electrical conductor, under normal conditions of temperature and pressure, is the silver metallic element. Silver is not always the ideal choice as a material, however, because it is expensive and susceptible to stains, and the oxide layer known as stains is not conductive.

Likewise, rust, verdigris and other oxide layers reduce conductivity even in the strongest conductors. The most effective electrical conductors are:








Sea water



Other strong drivers include:





Dirty water

Lemon juice

10 electrical insulators

Electrical charges do not flow freely through electrical insulators. This is an ideal quality in many cases. Electrical insulators considered “strong” are often used to coat or provide a barrier between conductors to keep electrical currents under control. This can be seen on rubber-coated wires and cables. The most effective electrical insulators are:



Pure water




Dry wood

Dry cotton


Other strong electrical insulators include:


Dry paper





Other factors that influence conductivity

The shape and size of a material affects its conductivity. For example, a thick piece of material will conduct better than a thin piece of the same size and length.

If you have two pieces of material of the same thickness, but one is shorter than the other, the shorter one will lead better because the shorter piece has less resistance, just as it is easier to force water through a pipe short than a long.

Temperature also affects conductivity. As the temperature increases, the atoms and their electrons gain energy. Some electrical insulators such as glass are bad conductors when cold, but good conductors when hot.

Most metals are better conductors when cold and less efficient when hot. Some good conductors become superconducting at extremely low temperatures.

Sometimes, the conduction itself changes the temperature of a material. Electrons flow through the conductors without damaging the atoms or causing wear. Moving electrons experience resistance, however. Because of this, the flow of electrical currents can heat conductive materials.
