Improved DC Properties of Polypropylene HVDC Cable Insulation by Grafting and Blending Combined Modification

High Voltage, Volume 11, Issue 1, Page 73-82, February 2026.
ABSTRACT In order to meet the needs of mechanical properties of cable insulation, polypropylene (PP) needs to be blended with low modulus materials to achieve toughening and softening. However, the compatibility between two or more resins can significantly affect the electrical properties of the composites.

A Hybrid Ultra‐High Voltage DC Transformer With Digital Twin‐Driven Operation and Control

Digital Twins and Applications, Volume 3, Issue 1, January/December 2026.
This study introduces a digital twin‐driven hybrid ultra‐high‐voltage DC transformer (UHVDCT) that combines high‐capacity LCCs with low‐capacity MMCs at the UHV side. This innovative topology reduces MMC requirements by 32.9% while ensuring stable power flow and dynamic reactive balance through real‐time virtual‐physical synchronization.

Long‐Term Thermal Stability of Electron‐Beam‐Irradiation‐Crosslinked Polypropylene Films for Power Capacitors

Electrical Materials and Applications, Volume 3, Issue 1, January/December 2026.
The polypropylene (PP) dielectric film undergoes severe degradation at high temperature. Electron‐beam irradiation crosslinking induces the formation of a compact spherulitic morphology in PP, which effectively restricts molecular‐chain mobility and hinders oxygen diffusion, thereby enhancing its long‐term thermal stability.
