In order to make the converter operate normally without the interference by EMF, the cable connecting the converter to a 3-phase motor must have high resistance to EMF interference, low effective capacitance and low transmission impedance.

• 为保持变频率器正常工作不受电磁干扰，因此连接变频器与三相交流电机之间的电缆就要求具有抗干扰性能、较低的有效电容及较低的传输阻抗。
