Impact of Fibres and Reinforced Nanoparticles on Tensile Strength of Transformer Oil-impregnated Paper

Reducing Hydrophilic Characteristics of Kraft Paper Insulation by Reinforcing With Surface Modified Rutile-TiO2 Nanoparticles

“…According to the authors' previous work [5] and El Omari et al [20], the rate of nanoparticles dispersion, particle agglomeration and amount of nanoparticles retained within the kraft paper nanocomposite influence the resultant properties of the fabricated paper. Therefore, reducing the water absorption characteristics of kraft paper with reinforced surface-modified nanoparticles is proportional to the amount of retained nanofillers, filler distribution and agglomeration.…”

“…The nanoparticles were surface modified with alkyl ketene dimer (AKD) in one case and in the other, with alkenyl succinic anhydride (ASA). In both cases, it was to condition the surface in mitigating moisture absorption [4], [5]. A filler retention aid was used to facilitate improved retention of the nanoparticles within the pulp fibre during the nanodielectric paper fabrication process.…”

“…The reliability of power transformers largely depends on the insulation [1]- [5]. In power transformers, the agents of insulation degradation include moisture, oxidation, and pyrolysis (heat) under the influence of electrical and mechanical stresses [1], [3], [6]- [8].…”

“…The present work explores the possibility of reducing kraft paper's water absorption characteristics using surfacemodified rutile-TiO2 nanoparticles (NPs). The authors' previous work [4], [5] presents details on how the rutile-TiO2 nanoparticles were fabricated and surface-modified to reduce moisture absorption and improve thermal stability properties. In the rest of this article, the process of the kraft paper nanocomposite fabrication is presented, followed by the analysis of the nanofiller retention rate within the kraft paper, morphology analysis of the paper, and the hydrophobicity tests in comparison with unfilled paper.…”
