Abstract
 With the progressive development of human society, electricity in our daily lives are playing an increasingly important role. As a clean energy, transmission and many other advantages of convenience, so increasing the greenhouse effect today underscores the importance of energy. And how to safe, reliable, economic and rational use of electricity led to more and more people attention. The design of plastic products factory methods used for distribution, not only to meet production needs, but also enable the power supply system is safe, reliable, economic rationality is that we run our first problem to be solved. What electrical equipment used in this design also have a significant impact. Therefore need to choose the right electrical equipment and the calculation of accurate information. The need for the design of the main factory plastic packet calculation of total load, the entire plant load, short circuit current calculation, the calculation of relay protection, lightning protection and grounding design for optional electrical equipment.
