S-30~31500kVA-NX1 Three-phase oil immersed transformer

In response to the national strategic goal of energy conservation and emission reduction, and combining with the characteristics of our own products, our company, in accordance with the requirements of the energy efficiency grades of energy-saving products in the GB20025-2020standard, through continuous research, development and improvement, has designed and produced transformer products of different energy efficiency grades that meet the requirements of the national standard.

Overview
Recommended Products

Through the research and application of new materials and new processes, as well as continuous independent innovation, and through the optimized design and continuous improvement of the iron core and windings, the goal of reducing losses and noise has been achieved, meeting the requirements of the national standard GB20025-2020.

Moreover, the noise level has decreased by 20% compared with the current national standard JB/T10088-2016, and the product performance has reached the domestic advanced level.

Compared with the energy efficiency grade ll products, the energy efficiency grade l products have lower losses.
