           额定电压 
           
           额定电压是电缆设计和电性能试验用的基准电压。 
           
           额定电压用U0、U表示,单位为V。 
           
           U0--任一绝缘导体和""地""(电缆的金属护层或周围介质)之间的电压有效值。 
           
           U--多芯电缆或单芯电缆系统任何两相导体之间的电压有效值, 
      RVV2*1.5
           当用于交流系统时,电缆的额定电压应至少等于所使用电缆系统的标称电压。该条件均适用于U0和U值。 
           
           当用于直流系统时,该系统的标称电压应不大于电缆额定电压的1.5倍。 
           
           注:系统的工作电压允许长时间地超过该系统标称电压的10%。如果电缆的额定电压至少等于该系统的标称电压,则电缆可在高于额定 电压10%的工作电压下使用。
