The product is suitable for use in power transmission and distribution lines with rated power frequency voltage 3.6/6kv~26/35kv.
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.
· 电缆导体的最高允许工作温度:90℃。
Max.admissible operating temperature of the conductor:90℃.
· 短路时(最长时间不超过5s)电缆导体的最高温度不超过2500C。
Max. short-circurt temperature of conductor shall not exceed 2500C.
(5s maximum duration)

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“最高系统电压”的最大值。
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
