In June 2022, our company's first 220kV uniform insulation transformer (3 units in batch) was successfully put into operation in Uzbekistan , which has the advantages of low losses and low noise. It has been highly recognized by customers, also indicates that the product series of our 220kV transformers have been further improved.
In the industry, uniform insulation transformers are commonly used at voltage levels of 72.5kV and below, but the voltage level of this project is 220kV, which is difficult to design. Technical problems such as 220kV uniform insulation, high-current heating on the low-voltage side, losses and temperature rise were solved during the project execution, which ensured smooth commissioning of the product.
