Problems solved by technology

[0002] With the rapid development of the electrical industry, it also promotes the rapid development of power boxes. There are more and more electrical equipment inside the existing power boxes. Many power boxes need to be exposed to the outside and work in harsh working environments. Therefore, for The performance requirements of the inverter power box are very strict, requiring it to have corrosion resistance, high temperature resistance, creep resistance and good toughness, but the power box on the market cannot meet the existing requirements, and its service life is short
