Nanobrick Wall Multilayer Thin Films with High Dielectric Breakdown Strength. [PDF]

ACS Appl Eng Mater, 2023
Current thermally conductive and electrically insulating insulation systems are struggling to meet the needs of modern electronics due to increasing heat generation and power densities. Little research has focused on creating insulation systems that excel at both dissipating heat and withstanding high voltages (i.e., have both high thermal conductivity

Anisotropic Dielectric Breakdown Strength of Single Crystal Hexagonal Boron Nitride [PDF]

ACS Applied Materials & Interfaces, 2016
Dielectric breakdown has historically been of great interest from the perspectives of fundamental physics and electrical reliability. However, to date, the anisotropy in the dielectric breakdown has not been discussed. Here, we report an anisotropic dielectric breakdown strength (EBD) for h-BN, which is used as an ideal substrate for two-dimensional ...

Dielectric Breakdown Strength of PDMS Elastomers after Mechanical Cycling

Energies, 2023
PDMS-based composites such as silicone elastomers are commonly found in high-voltage engineering, especially in outdoor insulation as coatings or structural elements or at interfaces between network elements, such as cable sealing ends (CSE). They are also promising prospects for dielectric elastomer generators (DEG), which are retrieving electrostatic

DC Breakdown Strength Of Dielectric Materials At Cryogenic Temperatures [PDF]

7 IEEE/PES Transmission and Distribution Conference and Exposition, 1979., 2005
The HVDC superconducting cable, under development at the Los Alamos Scientific Laboratory will operate at a temperature of 12 R and a helium pressure of 1.38 MPa. Because dc breakdown data of dielectric materials at these operating conditions were not previously available, extensive tests were performed on 11 dielectric materials in sheet form.

Study on Dielectric Properties of Nanoclay-Modified Disulfide-Containing Polyurea Composites [PDF]

Nanomaterials
To address the frequent faults (e.g., bird-related hazards, wind deviation) of transmission lines under extreme environments and the limitations of traditional insulating materials (insufficient dielectric properties, poor interface compatibility, etc.),
