Description

technical field

[0001] The invention relates to the technical field of transformer insulating oil, in particular to a transformer vegetable insulating oil with good heat conduction and heat dissipation performance and a preparation method thereof. Background technique

[0002] As an important liquid insulating medium, insulating oil is widely used in electrical equipment such as transformers. Mineral insulating oil is a liquid mixture composed of various hydrocarbons and is widely used due to its good electrical insulation, cooling properties and low cost. However, the ignition point of mineral insulating oil is low, and the fire safety performance is poor; at the same time, the biodegradation rate is low. If leakage or fire occurs, it will seriously pollute the environment, and it is difficult to meet the needs of high performance and environmental protection. Therefore, the development of new plant insulating oil It has gradually become a hot spot in the research of liqui...
