四、使用特性Operating characteristics

1、  额定电压Rated Voltage

电缆额定电压U₀/U(U_m)为：0.6/1(1.2)kV   

Rated Voltage of cable U₀/U(U_m)：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

U_m：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 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：包括不属于A类和B类的系统。

System category C ─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.
