The use of static frequency converters, which have a high switching frequency, generates
voltage pulses with a high rate of change over time. In combination with cable and motor …

The premature failure phenomenon that occurs in solid insulation under the application of
repetitive impulse voltages is known as the accumulative effect of impulse voltages on a …

To improve the dielectric properties and corona resistance of epoxy resins (EPs), the authors
designed and synthesized Si‐B‐Mg/EP nanocomposites and investigated the effects of …

Insulation performance of the dielectrics under extreme conditions always attracts
widespread attention in electrical and electronic field. How to improve the high-temperature …

Polyimide nano-composite film (Kapton 100CR) is a special type of engineering plastic film,
which is widely used in turn insulation of form-wound inverter-fed motor. Partial discharge …

To make clear the effect and mechanism of sericite mica (SM) modified by silane coupling
agents (SCA) on the morphology and properties of polyimide (PI) composites, the SM …

High-frequency trend of electrical equipment puts forward higher requirements on the
dielectric properties of insulating materials, especially under corona ageing environment …

A novel method using montmorillonite-AlN (MMT-AlN) composite particles as dopants in
polyimide (PI) has been proposed and tested. We choose MMT-AlN as dopants in PI for …

Owing to the possible interfacial mismatching, the insulation performance in the polyimide-
Epoxy (PI-EP) dual-layer composite structures would be reduced. In this paper, molecular …

Polyimide (PI) films have excellent electrical, mechanical and thermal properties in aspect of
resisting corona, aging and radiation. However, the pulse voltage combined with dc voltage …
