In order to reduce the radiated electromagnetic interference of the power cable,especially the feeder cable of the frequency conversion device,the copper tape armored shielded power cable should be used,which can achieve satisfactory results and reduce the electromagnetic interference generated by the power line.Different types of signals are transmitted by different cables.Signal cables should be laid in layers according to the type of transmission signals.It is strictly forbidden to use different wires of the same cable to transmit power supply and signals at the same time.Avoid laying signal lines and power cables in parallel to reduce electromagnetic interference.
为了减少动力电缆辐射电磁干扰，尤其是变频装置馈线电缆，应采用铜带铠装屏蔽电力电缆，能够取得满意的效果，从而降低动力线产生的电磁干扰。不同类型的信号分别由不同电缆传输，信号电缆应按传输信号种类分层敷设，严禁用同一电缆的不同导线同时传送动力电源和信号，避免信号线与动力电缆靠近平行敷设，以减少电磁干扰。
