Effect of power supply parameters on equipments for a foreign-aiding project

Based on the design example of a foreign-aiding project, analyses the different effects of power supply parameters on common equipments. Points out that in the condition of this project, the ventilator and pump made in China cannot be directly used in the recipient country. But at the early stage of design, it is viable to reserve power for ventilator and pump based on Chinese domestic catalog. Electric water heater made in China can be used in the project.
