· the role of insulating material insulation is the electrical equipment in the different potential of the charged part isolated. 1. insulation material has a high insulation resistance and compressive strength, to avoid leakage, breakdown and other accidents.
· optimum utilization of these materials according to their electrical, mechanical, physical, chemical and thermal characteristics is important for using an appropriate insulating material. the insulation class of a power transformer is decided on the test level of which insulation
an electrical insulator provides very high resistance so that practically no current can flow through it. insulating materials basically, an insulating material or insulator contains a very small amount of free electrons (charge carriers) and, hence, could not carry electrical current.
