Dielectric constant is a function of molecular structure of a material, and dictates how an applied voltage will be "shared" by the components of an insulation system. Dielectric constants must be considered especially when working with high voltage, as an incorrect choice of components (one with a Dielectric Constant very different from the other components) can cause a dielectric breakdown due to an imbalanced voltage share. Dielectric constant is also a function of applied frequency. The dielectric constant at 60 Hz for all of our products is 2.2 - 2.25.
The dielectric breakdown strength, as measured by ASTM Method D1816 (hemispheric electrodes, 2 mm apart) is > 60 KV.
