Abstract: It is generally believed that the service life of transformer oil-paper insulation is determined by the aging condition of transformer insulation paper. In order to further improve the anti-aging performance of transformer insulation paper, the cellulose nanocrystals (CNCs) modified by citric acid crosslinking and melamine amidation, were used to prepare the transformer insulation paper. The insulation paper containing modified CNCs was characterized with Fourier Transform Infrared Spectroscopy, X-ray diffractometry and Scanning Elect...
