Rated A.C. Voltage between conductor and ground/me🎉tal screen;

U:电缆线定制用的导体间的額定工频电阻值;

Rated A.C. Voltage between conductors

Um:机械设备可背负的“上限机系统相电压“的最好值。

The maximum system voltage whic🍸h the equipme🌟nts can be beared

电力高压电线电缆的额定功率工作电压应非常适合电力高压电线电缆所在区域程序的执行经济条件。以便更加方便选择电力🔴高压电线电缆,将程序分布为下面三大类:

The rated voltage of cable shall be applicable to system operation condition where the cable lain in. According to cable selecting, the system will be🐭 described as 3 types as follow:

——A类:同一个相导体与地或接地线导体接触到时,能在1min内与模式隔離。

System category A —When any phase of cable conductor is contacting with earth conductor, the cable will be isolated     with t⛎he system.

——B类:可在三相变频器跨接故💯障率时作短时间开机运行,但任何的状态下不可已经超过8h,每人每年接地装置故章总快速时不可以上125h。

System category B—The system is allowed to run for 8 hours, when the single-phase earth fault is existing. And the total earth-fault time of 1 year won't be above 125 hours.

——C类:也包括不是一种A类和B类的系统。

System categoryC —They are including all systems besides A and B.

注:在操作整体的接地线极错误代码并不能即刻一键缓解时,错误代码当天加在电力高压电缆绝缘电阻去过高的电场标准标准,会在某种地步上不但缩减电力高压电缆平均寿命。如操作整体的期望会总是地进行在更久的接地线极错误代码状态下下,该操作整体的应划为C类。

When the system earth fault can't be removed automatically, the life of cable will be shortened in some degree because of the over-high electric stess beared by cable insulation.
