But you can't just consider the tub size â they're all designed to be dropped into a deck, and that will take up more space, with the bare minimum adding at least a half-inch to your measurements on all sides.
Report Abuse. Scope: Dielectric Strength is a measure of the electrical strength of a material as an insulator. Dielectric strength is defined as the maximum voltage required to produce a dielectric breakdown through the material and is expressed as Volts per unit thickness.
Dielectrics Dielectrics is a fancy term for insulators, based on the material used and its efficiancy at a measured range of frequencies. For example, in a coaxial cable, the better it isolates the main frequency from feeding through to the shield, the higher the dielectric value.
