摘要
国内引进了多套美国ＰＯＹ长丝生产设备．其额定电压和频率与国内低压电网的电压和频率不同．通过分析，提出了切实可行的供电方法和应该采取的技术改造措施．
Many sets of POY preductive equipment of long fibre have been imported from America.Their rated Voltage and frepuency are different from the Voltage and frequency of electrified wire nettingof olw Voltage of China. Through analysis,we put forward the practical method of power supply and the technical reform measures to take.
