In this work, an in-situ testing platform that could simultaneously apply high voltage (HV) and
mechanical stress has been established. The dielectric properties evolution of aramid fiber …

In this article, aramid fiber surface is treated by dielectric barrier discharge (DBD) plasma,
and various aramid fiber reinforced epoxy composites (AFRCs) are prepared to investigate …

The poor interfacial adhesion between aramid fiber and epoxy resin is the main issue
affecting the dielectric properties of the aramid fiber-reinforced composite (AFRC). In this …

Epoxy resins are widely used in equipment such as ultra-high voltage dry-type bushings,
which are subjected to severe electric, thermal, and compressive stresses. Some physical …

In this article, the positive and inverse gradient symmetric magnetic field and the asymmetric
magnetic field with different angles are constructed. The influence of the magnetic field …

In this paper, aramid fiber surface is modified by polyethylenimine (PEI) grafting with
abundant-NH 2 active groups after plasma surface activation treatment. Various aramid fiber …

Epoxy/Al2O3 composite is widely used in high-voltage gas insulation equipment and cable
terminals because of its excellent heat resistance, mechanical properties, and dimensional …

In polymeric insulating materials, electrical treeing often precedes breakdown. Nanometric
fillers in polymers have been reported to have a tree-retarding effect. In order to effectively …

High voltage alternative current (HVAC) gas insulated transmission line (GIL) bears a strong
electric field and complex mechanical stresses during operation. As one of the main …

In this study, the treeing characteristics of epoxy resin were investigated by stressing the
sample parallel or vertically to the needle axis. Results show that tensile stress accelerates …
