本产品适用于固定敷设在交流50Hz， 额定电压35kV及以下的电力输配电线路上作输送电能用。 与聚氯乙烯绝缘电力电缆相比， 交联电力电缆产品不仅具有优异的电气性能、 机械性能、 耐热老化性能、 耐环境应力和耐化学腐蚀性能的能力，而且结构简单， 重量轻， 不受敷设落差限制， 长期工作温度高（90℃）等特点。
一、 生产执行标准
GB/T12706.1-2008~ GB/T12706.3-2008《额定电压1kV（Um=1.2 kV） 到35kV （Um=40.5 kV）挤包绝缘电力电缆》 ，也可按用户需要， 采用国际电工委员会IEC60502-1997标准生产。
二、 使用特点
1、 电缆导体的允许长期最高工作温度为90℃。
2、 短路时（最长持续时间不超过5秒） 电缆导体的最高温
度不超过250℃。
3、 电缆敷设时的环境温度不得低于0℃。
4、 电缆的最小弯曲半径： 三芯电缆不小于电缆外径的15
倍； 单芯电缆不小于电缆外径的20倍。
5、 电缆的工频额定电压U0/U为0.6/1kV~26/35kV。
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， 称相电压；
U： 电缆设计用的导体间的额定工频电压， 称线电压；
Um： 设备可承受的“最高系统电压”的最大值。
The cable is used to transmit power on the power transmission and distribution line of A.C. 50Hz, rated volt-age 35 KV or lower. By comparison with power cable with PVC insulation, it has not only excellent electric perfor-mance, mechanical performance, heat & aging resistant performance, weather resistant performance, chemical corrosion resistant performance, but also simple structure, light weight, no restriction by laying drop, and high tem-perature allowance for long term working(90℃) as well.
Executive standard
As section “extruded insulation power cable with rated voltage from 1kV（Um=1.2 kV）to 35kV（Um=40.5 kV） ” stipulated in GB/T12706.1-2008~ GB/T12706.3-2008 or IEC60502-1997 according to the requirement of the customer .
Working Condition
1、 Long-term working temperature by cable conductor is 90℃.
2、 Max. temperature of cable conductor shall be no more than 250℃ during short circuit (the longest lasting time shall be no more than 5 seconds).
3、 Environment temperature for installation is no less than 0℃.
4、 Min bending radium of cable:
It is no less than 15 times that of cable outer diameter for cable with three cores.
It is no less than 20 times that of cable outer diameter for cable with single core.
5、A.C. rated voltage U0/U of cable is 0.6/1kV~26/35kV.
U0: rated A.C. voltage of conductor to earth OR between metallic shielding for cable designing, which is called phrase voltage.
U： rated A.C. voltage between conductors for cable designing, which is called wire voltage.
Um: Max endurable value of “Max system voltage” for cable Working Condition
