详细介绍：

6kV~35kV 中低压铜芯及铝芯交联聚乙烯绝缘电力电缆（YJV电缆，YJV22电缆，YJLV电缆，YJLV22电缆）

使用特性 Operating characteristics
· 工频额定电压U0/U为3.6/6kv～26/35kv。
Rated power-frepuency voltage U0/U: 3.6/6kv～26/35kv.
· 电缆导体的zui高允许工作温度：90℃。
Max.admissible operating temperature of the conductor:90℃.
· 短路时（zui长时间不超过5s）电缆导体的zui高温度不超过2500C。
Max. short-circurt temperature of conductor shall not exceed 2500C.
（5s maximum duration）
· 电缆敷设时环境温度应不低于00C。
The ambient temperature under installation should not below 00C.
· 电缆弯曲半径：三芯电缆不小于电缆外径15倍；单芯电缆不小于电缆外径20倍。
The bending radius of a single-core cable should not less than 20 times of the cable diameter.
The bending radius of a single-core cable should not less than 15 times of the cable diameter.
电缆额定电压的选择 Voltage designation
· 电缆的额定电压应适合于电缆系统的运行状况，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“zui高系统电压”的zui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.
· 三相系统用电缆的U0值推荐如下表：
The values of U0 recommened for cable to be used in three-phase systems are listed below:

U kv	U m kv	U 0 * kv
U kv	U m kv	A 和 B 类系统 System categories A and B	C 类系统 Systems categories C

A类系统──该类系统任何一相导体与地和接地导体接触时，能在1min内与系统分离
B类系统──该类系统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，zui长不超过8h每年接地故障总持续时间不超过125h；
C类系统──不属于A类、B类的系统。
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
