S(B)22-NX1 (Energy Efficiency Level 1):As a high-end 10kV oil-immersed transformer, the "NX1" achieves all-round optimization—the iron core uses laser-cut silicon steel sheets with a lamination factor of 97%; the windings use transposed conductors to reduce skin effect loss; the oil tank is equipped with an intelligent oil level monitoring and automatic cooling system. Under Level 1 energy efficiency standards, the loss indicators meet the highest requirements of the national standard GB 20052-2020. It is suitable for key power supply scenarios such as urban core area distribution networks and large commercial complexes. The equipment supports condition-based maintenance, reducing operation and maintenance costs by 40%.
