Investigating the Impact of Hardness on Dielectric Breakdown Characteristics of Polyurethane. [PDF]
ACS OmegaPolymeric materials play a vital role in high-voltage insulation, but their insulating properties can deteriorate over time, leading to insulation failures. The presence of voids resulting from manufacturing defects or external stresses can create a highly divergent field, further contributing to this issue.
