Insulating materials and its characteristics

One of the major characteristics of the insulators in power system is the resistance to the current flow (passage of the current), since when electrically charged, it “traps” electrical charges inside. No wonder it is widely used to block its passage.

In addition, there are some types of electrical insulators that can be polarized. That is, when exposed to an enormous external energy field, it creates an opposite electric field inside, making the formation of electrical currents even more difficult. Materials with this characteristic are called dielectrics.

It is worth remembering that for opposing the movement of loads, electrical insulators are widely used to insulate contact surfaces. Thus, it is possible to avoid electrical shock or loss of energy in conductive wires and cables. Taking this into account, before making the electrical wiring of homes and commercial environments, it is really important to make sure that the cables have a good insulator of electricity. This attitude will help you to make the place much safer.

There are insulators with different functions and models like suspension insulator, post insulator, pin insulator, LV insulator and so on. And these insulators have to work with some accessories like porcelain bushing, high voltage protection device and metal fitting.
