电缆额定电压的选择 Voltage designation
· 电缆的额定电压应适合于电缆系统的运行状况，用U0/U（Um）kv表示。
U0－电缆设计用的导体对地或金属屏蔽之间的额定工频电压；
U－电缆设计用的导体间的额定工频电压；
Um－设备可承受的“ 系统电压”的大值。
The rated voltage of the cable for a given applixation shall be suitable for the operating conditions
in the system in which the cable is used,and is expressed in the form of U0/U（Um）kv
Where:
U0－The rated power-frequency voltage between conductors and earth metallic screen ,for which the cable designed;
U － The rated power-frequency voltage between conductos, for which the cable designed;
Um－ The maximum value of the“highest system voltage”for which the equipment may beused.
