四、使用特性Operating characteristics

1、  额定电压Rated Voltage

电缆额定电压U0/U(Um)为:0.6/1(1.2)kV

Rated Voltage of cable U0/U(Um)::0.6/1(1.2)kV 

其中:Notes

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;

Rated A.C. Voltage between conductor and ground/metal screen;

U:电缆设计用的导体间的额定工频电压;

Rated A.C. Voltage between conductors

Um:设备可承受的“最高系统电压“的最大值。

The maximum system voltage which the equipments can be beared

电缆的额定电压应适合电缆所在系统的运行条件。为了便于选择电缆,将系统划分为下列三类:

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:任一相导体与地或接地导体接触时,能在1min内与系统隔离。

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

——B类:可在单相接地故障时作短时运行,但任何情况下不宜超过8h,每年接地故障总持续时间不宜超过125h

System category BThe 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:包括不属于A类和B类的系统。

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

注:在系统接地故障不能立即自动解除时,故障期间加在电缆绝缘上过高的电场强度,会在一定程度上缩短电缆寿命。如系统预期会经常地运行在持久的接地故障状态下,该系统应划为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.
