The cable is determined by the size of the power (converted to current) and the distance from which the distance is far. The greater the power distance, the greater the cross-sectional area of the required cable. For example: 15KW motor selection cable current I = P / 1.732UcosΦ = 15 / 1.732 / 0.38 / 0.8 = 28A if it is close (within tens of meters), copper cable 6 square millimeters, aluminum cable 10 square millimeters.
