自己查到的一些资料,供大家参卡, 以300/500V为例
rated voltage U。(300V)---the power-frequency voltage to earth for which the cable is designed 额定电压U。是电线跟地面的电压
rated voltage U (500V)----- the power-frequency voltage betwwen conductors for which the cable is designed 额定电压U是导体之间的电压
Voltage designation 额定电压表达方法
The cable shall be designated by the rated voltage U。and U expressed in the formed U。/U unless otherwise specified in the appropriate cable standard. 除非适用的电线标准有具体规定,否则电线的额定电压应该以U。/U的形式表示。
In an a.c. system, the rated voltage of a cable should be at least equal to the nominal voltage of the system for which it is intend. This condition applies both to the value U。and the value U. 在交流系统中, 电缆的额定电压最少应该等于系统的标称电压,并且同时适用于U。 和U.
根据这些资料,大家能不能帮忙解答一下上面的问题啊?
