电缆额定电压的选择
Rated voltage of cable ion
1、电缆的额定电压应适合于电缆使用系统的运行状况，用U0/U（Um）KV表示。
2、U0—电缆设计用的导体与屏蔽或金属套之间的额定工频电压；
3、U—电缆设计用的导体之间的额定工频电压；
4、Um设备可承受的“系统电压"的值。
5、三相系统用电缆的U0值，推荐如下表：
1、The rated voltage of the cables shall be suitable for operation in cable system, using U0/U (Um) KV.
2、U0 cable design with the conductor and the shield or metal between the sets of rated voltage;
3、Rated power frequency voltage between U - for the design of the cable conductor;
4、Um equipment can withstａnd the "highest system voltage" maximum.
5、Three-phase system with cable U0, recommends the following table:
| U | Um | U0 | |
| 类电缆 First kind of cable | 第二类电缆 Second kind of cable | ||
| 1 | -- | 0.6 | 0.6 |
| 3 | 3.6 | 1.8 | 3.6 |
