1.definition
Resistance coefficient greater than 10 9 times the square Ω.cm material in the electrical technology is called insulation material.
His role is to isolate the potentials in electrical equipment. Therefore, the insulating material should have good dielectric properties, that is, with a high insulation resistance and compressive strength, and to avoid leakage, creep or breakdown and other accidents.
Second, especially the heat resistance is good, especially in the long-term heat (heat aging) and the performance of the most important changes; in addition to good thermal conductivity, moisture and a higher mechanical strength and process processing and so on.
2.Performance
Electrician commonly used insulating material performance indicators such as dielectric strength, tensile strength, specific gravity, expansion coefficient.
(1) Compressive strength: Insulating material In the electric field, when the electric field strength increases to a certain limit, it will breakdown. The electric field strength of the insulation breakdown is called the dielectric strength (also known as dielectric strength or dielectric strength), which is usually expressed as the voltage KV of 1mm thick insulating material.
(2) Tensile strength: insulation material per unit cross-sectional area can withstand the tension, such as glass per square centimeter cross-sectional area can withstand 140 kg.
(3) Density: The mass of the insulating material per cubic meter, for example, 2 grams per cubic meter of sulfur.
(4) expansion coefficient: the insulator after the increase in the degree of volume.
