Effect of micro–sized filler loading on surface erosion of silicone rubber composite insulators
, 2012 Polymeric materials such as silicone rubber (SiR) are widely used in high voltage outdoor insulating systems and it has been shown that a practical solution to improve the thermal characteristics of SiR is to add micro-sized inorganic particles ...

Advanced Functional Materials, EarlyView.Multiscale experiments and modeling reveal how Ti3C2Tx MXene nanosheets reinforce PVDF nanocomposites. An optimal MXene loading (∼1 wt.%) nearly doubles tensile strength through efficient stress transfer, flake alignment, and crack‐deflection mechanisms, transforming ductile polymer behavior into a controlled multi‐stage fracture pathway which aligns ...

Structure Change of the Insulating Composite
Advances in Electrical and Electronic Engineering, 2008 Modern power electric drives brought advantages in induction motor control. In the same time appeared problems with high frequency square waveform voltage (pulse stress) produced by the voltage converters. Voltage converters produce repetitive pulses with high level of voltage rise fronts (slew rates).

Modelling abnormal temperature increases on composite insulators and influencing factors
In recent years, abnormal hot spots of composite insulators on overhead lines have been frequently observed, seriously affecting the reliability of transmission lines and the system security of the power network. Once hot spots are detected, the strategy
