Electrical Solid Insulting Material Testing
The most significant insulating material is air. Beside that solid, liquid, and gaseous type of insulators are also used in electrical systems. A material that responds with very high resistance to the flow of electrical current or totally resists electric current is called an insulating material. ... Material like PVC, glass, asbestos, rigid laminate, varnish, resin, paper, Teflon, and rubber are very good electrical insulators. These properties include dielectric breakdown voltage, dielectric strength, AC loss, permittivity (dielectric constant), DC resistance and conductance, dissipation factor, ion exchange capacity, ionic resistivity, and other physical properties. These electrical insulating material standards allow manufacturers, particularly those in the semiconductor industry, to examine and asses such materials and equipments to ensure their qualification for safe use.A material that responds with very high resistance to the flow of electrical current or totally resists electric current is called an insulating material. Material like PVC, glass, asbestos, rigid laminate, varnish, resin, paper, Teflon, and rubber are very good electrical insulators.Insulating material is used as a protective coating on electrical wire and cables. The most significant insulating material is air.
Why electrical insulation is Required
Electrical shock caused by the flow of current through the human body can result in physiological effects raging from fatal injuries resulted by involuntary moments to death from ventricular fibrillation (the rhythmic pumping action of the heart ceases) or muscular contraction.
