On the basis of the S9 series, the S11 series oil immersed transformers have an average reduction of 30% in no-load losses; The no-load current decreases by 70-85% compared to S9; The average temperature rise is reduced by 10K, and the product's service life is more than doubled. Even under conditions of overload of 20%, it can still operate for a long time; The average noise reduction during product operation is 2-4 decibels.
