yjv22-10kv铜芯电缆，yjv22-3*240每米重量及价格电缆额定电压的选择   Voltage designation

缆的额定电压应适合于电缆的运行状况，用U0/U（Um）kv表示。
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；
U－电缆设计用的导体间的额定工频电压；
Um－设备可承受的“高电压”的大值。
The rated voltage of the cable for a given applixation shall be suitable for the operating conditions
in the system in which the cable is used,and is expressed in the form of U0/U（Um）kv
Where:
U0－The rated power-frequency voltage between conductors and earth metallic screen ,for which the cable designed;
U － The rated power-frequency voltage between conductos, for which the cable designed;
Um－ The maximum value of the“highest system voltage”for which the equipment may beused.
· 三相用电缆的U0值推荐如下表：
The values of U0 recommened for cable to be used in three-phase systems are listed below:

A类──该类任何一相导体与地和接地导体时，能在1min内与分离
B类──该类仅包括单相接地故障短时运行的条件，接地故障时间应不超过1h, 但在任何情况下，长不超过8h每年接地故障总时间不超过125h；
C类──不属于A类、B类的。
System category A──This category comprises those systems in which any phase conductor that comes in contact with earth or an earth conductor. is disconnected from the system within 1 min.
System category B ──This category comprises those system which,under faultconditions,are operated,are operated for ashorttimewith one phase earthed.This period should not exceed 1 h..Fora longer period, not exceeding 8h on any occasion, can be tolerated.The total duration of earth faults in any year should not exceed 125h.     
System categeory C──This category comprises all systems which do not fall into A and B
