1. Distinctiveness
（1）Strong load adaptability
Oil immersed transformers have strong load adaptability and can adjust input and output currents as needed to meet different load conditions.
（2）Easy maintenance
Oil immersed transformers usually only require regular inspection and replacement of oil, and necessary insulation tests to maintain normal operation. This reduces the complexity and cost of maintenance.
（3）Good heat dissipation performance
The oil in oil immersed transformers has good heat dissipation performance, which can effectively dissipate the heat generated inside the transformer, thereby ensuring the long-term stable operation of the transformer.
2. Usage Scenarios
Motor control and drive systems: Three-phase three-winding transformers are widely used in the industrial field for motor control and drive systems to control the starting, stopping and speed regulation of motors. They can meet the different power requirements of different industrial equipment and improve the stability and efficiency of the production process.
