Problems solved by technology

[0002] A good transformer oil should be a clean and transparent liquid without sediment, mechanical impurity suspension and cotton-wool-like substances. If it is polluted and aged, resin and sediment may be produced, and the oil quality of the transformer oil will deteriorate. How to make the product A transformer oil with good stability, aging resistance and good antibacterial properties has become a technical problem that needs to be solved at present
