The GB20052-2024 standard energy-saving product, energy efficiency level 1 oil-immersed transformer, is a product independently developed by our company on the basis of the original model. Through the research and application of new materials and new processes, combined with independent innovation and technology introduction, and by optimizing and innovatively designing the core and coil structures, it achieves the purpose of reducing no-load loss and noise.
The use of high-permeability cold-rolled silicon steel sheet effectively reduces no-load loss.
The corrugated tank is equipped with a pressure release valve to isolate air, delay oil degradation, and achieve true maintenance-free operation.
The corrugated wall integrates three functions (cooling / breathing / expansion) to adapt to oil volume changes. The vacuum-annealed core is epoxy-cured, with a design life of up to 30 years.
The noise level is reduced by an average of 20% compared to the current national standard JB/T10088-2016. The product's performance level reaches the domestic advanced level.
Compared with energy efficiency level 2 products, energy efficiency level 1 products have lower losses.
