The company applied for its first patent

There are many entrepreneurs who own patents, but very few of them from their own inventive activity. With Chang Jiang's first patented invention "Multi-function motor protector", HCET launched the first motor protector with multiple functions in the Chinese market. The appearance of the protector solves some potential safety problems before, and provides more reliable safety protection for the motor. Since its invention, this versatile motor protector is still one of the best-selling products in the industry.
