Abstract: It has significant meaning for doing the relevant compatibility tests. Because the poor compatibility might lead to the deterioration of plant insulating oil or rubber materials and affect the safe operation of power equipment. This paper examined the compatibility of nitrile rubber, hydrogenated nitrile rubber, vegetable oil-resistant nitrile rubber with vegetable insulating oil and analyzed the results while collating and comparing test data. This study explains the existing defects of the use of nitrile rubber in vegetable oil and provides a reference for the application of vegetable oil-based transformers.
Key words: nitrile rubber(NBR); vegetable insulating oil; compatibility; transformer
