Do you know what is a polymer insulator? Here, we will teach you about it. This material offers opposition to the passage of electrical charges. This means that electrons are strongly bound to atomic nuclei, which is why this compound is not easily conducted.
Although there are no materials that make isolation 100% perfect, there are several compounds that help to slow down flames in the event of a short circuit. Are you interested in this subject and want to know more information about polymer insulator? Then, keep reading our article!
What is a polymer insulator?
Are polymers insulators? Yes! This kind of polymer is a material resistant to electron flow because of the low amount of subatomic particles. This causes the electrical charges to have difficulty transit through the body.
In thermal insulating polymers, valence electrons are attached to atoms, while the dielectric strength found in the formation is attached to an insulating element. In practice, we can say that electrical insulators are basically the opposite of electrical conductors.
These electrical insulating materials are widely used in the electrical and electronics sectors as elements to isolate electricity in protective equipment for living beings or in electrical circuits.
For more details about the polymer insulator characteristics, check out our full article. There, you will find the differences between resistance and conductivity, in addition to the main characteristics of the insulators.
Why use a polymer insulator?
As we said earlier, the main polymer insulator specifications are the few electrons and the resist its flow, avoiding the chances of thermal shock. Some materials found in this category are:
- plastic (resin);
- glass (ceramic);
- pure deionized water.
The main reason why these materials are used as insulators is the high resistance to the load-flow. These electrical properties of polymers make it perfect for wrapping copper electrical wires, whether in a dryer cable or a high-voltage tower.
What makes electrical insulating materials good electricity conductors is the enormous amount of free electrons it presents at room temperature. With the insulating element, this happens the opposite way since it has few free electrons in the local climate.
To make this clearer, think about wood as an example. A piece of this material can only be considered insulating up to a certain voltage class. If it is raised to other levels, the wood is free to become an electrical conductor.
How about knowing the polymer insulator of Polyexcel?
Considered one of the greatest producers of polymeric compounds in Brazil, Polyexcel has been producing high-performance resins for nine years. For this, the company has a team of specialists who are always looking for innovative research to improve the production of polymeric insulators.
Polyexcel also follows all current laws so that professionals and customers are safe in using the products. One of the certificates that guarantee the quality in the production of the compounds is ISO 9011, which can be accessed on the website’s home page.
One of the biggest differentials of the company is the fact that it operates in the Brazilian market, using international technology. Another positive point is that there is training to present the products, besides quick response to questions regarding the application of each compound.
There are some polymer type insulator at Polyexcel to cover power and telecommunications wires and cables. Among it is XLPE, HEPR, and HDPE. The first one is an ethylene-based compound, which provides a working temperature class of 194ºF.
The second is a thermoset polyethylene with the addition of an elastomer, which gives the cable greater flexibility. The third is a high-density thermoplastic polymer, stabilized by UV light and resistant to electrical tracking.
