This paper deals with complex nanocomposite, which was developed. The nanocomposite is based on epoxy resin modified by nanosilica and nanofabric. As a matrix was used epoxy resin DGEBA based on bisphenol A with hardener Laromin C260 and particles hydrophobic nanosilica — AEROSIL R 974. As filler Ultramid — Polyamide 6 garneted in an electrostatic field. It was verified optimum amount Nano additives...
This paper deals with the effect of inorganic micro/nanofillers and nanofabric on electrical tree growth in high voltage insulation. Experiments were conducted at a constant AC voltage of 20 kHz, 50 Hz epoxy samples without any fillers as well as epoxy nanocomposites with hydrophobic nanosilica or hydrophilic microsilica or polyamide nanofabric. The time to breakdown tree was observed and the transparency...
