What is natural ester insulating oil

2024-07-19

Natural ester insulating oil is a kind of insulating oil obtained through the refining of plant seeds, which has the advantages of high ignition point, environmental friendliness, high natural degradation rate, etc., and eliminates the insulating air gaps in electrical equipment by impregnation and filling. The natural ester has a high degree of water saturation and can effectively absorb water in the insulating paper, thus inhibiting the aging of the insulating material. At the same time, our country has abundant sources of oil crops, which in turn lays a material foundation for the wide application of natural ester insulating oil.
