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

Abstract

Improved dielectric properties of oil-impregnated papers, modified with nanoparticles justify the nanotechnology as a promising tool to resolve major setbacks associated with kraft papers for power transformer applications. However, the impact of nanoparticles on tensile strength of a modified oil-impregnated paper is rarely discussed in literature. In this work, the kraft paper insulation was modified with rutile-titanium dioxide nanoparticles (rutile-TiO2 NPs). The process of synthesis, surface modification and fabrication of insulation papers including phase characterization is presented. The tensile strength of papers was examined and analyzed. The influences of fibre and nanoparticles parameters on the resultant tensile strength are discussed.
