Dielectric Strength Breakdown
When looking at DBS values, it is important to consider at what thickness the measurement was taken. Materials tested in thin sections will yield higher DBS values in kV/mm than materials tested in thick sections.
Ideally, both thick and thin materials would yield the same DBS results, since the units are electric potential per thickness, but with thicker materials come more impurities, no matter how small, which will ultimately lead to a decrease in DBS.
Why is Dielectric Stength Important?
Dielectric strength is an important property for materials used in electrical and electronic applications, such as EVs, e-motors, transformers, and charging systems.
Materials with high dielectric strength and high thermal conductivity are preferred in these applications because they can withstand higher voltages and provide better electrical insulation, which helps to prevent electrical failures and improve the reliability of the components and systems.
