Summary: This research conducted numerous steep-front impulse voltage tests on various types of insulators, revealing that the degradation in performance of coated insulators is mainly caused by the RTV coating rather than intrinsic defects. The breakdown mechanism of coated insulator under steep-front impulse was illustrated, and a numerical simulation of electric field distribution was performed for verification. Different controlled experiments were conducted to validate the theory, and a proposed modification towards the current coating method was presented.

Summary: This paper investigates the effect of different nanofillers on the mechanical and thermal properties of PEI/silicone rubber nanocomposites. The incorporation of modified HNT at 3 phr loading significantly increases tensile strength, tensile modulus, storage modulus, and glass transition temperature. The enhancement of glass transition temperature may be due to restricted movement of polymer chains and the formation of HNT zig-zag structures.
