In petrochemical enterprises, the voltage loss calculation is used to check the bus voltage loss and motor terminal voltage when feed line normal running or motor starting .At the same time, voltage loss of control circuit should be confirmed. In this paper, by means of detailed calculation based on line voltage loss, under the condition of meeting the requirements of various technical parameters, more feasible design scheme was determined through the comparison of project investment, namely improving the line cable section to reduce the voltage loss and make the project investment more reasonable.
