聚氯乙烯绝缘及护套控制电缆GB9330一、产品标准本产品按GB9330《塑料绝缘控制电缆》，IEC60027《额定电压450/750V及以下聚氯乙烯绝缘电缆》以及IEC60520《额定电压1/30KV挤包绝缘电力电缆及附件》等标准制造。
安装要求1)发热和散热能力决定变频器的输出电流能力，从而影响变频器的输出转矩能力。
2)载波频率:一般变频器所标的额定电流都是以最高载波频率，最高环境温度下能保证持续输出的数值。
降低载波频率，电机的电流不会受到影响。
但元器件的发热会减小。
3)环境温度:就象不会因为检测到周围温度比较低时就增大变频器保护电流值。
4)海拔高度:海拔高度增加，对散热和绝缘性能都有影响.一般1000m以下可以不考虑。
以上每1000米降容5%就可以了。
