[0002] Transformer insulating oil is a product of petroleum refining and distillation. Its main components include compounds such as alkanes, cycloalkane saturated hydrocarbons and aromatic unsaturated hydrocarbons. It is mainly a light yellow transparent liquid. The main function of transformer insulating oil is to dissipate heat and cool the transformer inside, to keep the windings in a relatively good insulation state, or to act as a liquid seal at the electrical connection. Normal transformer insulating oil is a light yellow transparent liquid, which is relatively clean and transparent. When transformer insulating oil is produced, it needs to be washed with water through a water washing device. After the transformer insulating oil is washed with high-temperature water, it is drained, dehydrated, crystallized, and filtered.
