Description

technical field [0001] The invention relates to the technical field of transformer oil, in particular to a transformer oil with excellent fluidity. Background technique [0002] Transformer oil refers to a type of insulating oil used for insulation, cooling, information carrier and protection in oil-filled electrical equipment such as transformers, reactors, transformers, bushings, and oil switches. The main functions of transformer oil are insulation, heat dissipation and arc suppression. Due to its good insulation performance, it plays a role of insulation and insulation maintenance for windings; transformer oil has a large specific heat and is often used as a coolant. In use, transformer oil is required to have cooling and heat dissipation properties, insulation properties, solubility, electrical properties, low temperature properties, gas evolution properties and oxidation stability properties. The transformer oil in the prior art has poor fluidity, short storage time ...
