4、敷设电缆时环境温度应不低于0℃。
5、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。
1、AC rated voltage U0/U 3.6/6~26/35KV.
2、Long-time working max.temperature is 90℃.
3、Short-circuit temperature is not more than 250℃,lasting less than 5 seconds.
4、Laying temperature of cable should be not less than 0 ℃
5、Bending radius of cable: cable with three cores of not less than 15 times of the cable diameter; the single core cable is not less than 20 times of the cable diameter.
电缆额定电压的选择
Rated voltage of cable ion
1、电缆的额定电压应适合于电缆使用系统的运行状况,用U0/U(Um)KV表示。
2、U0—电缆设计用的导体与屏蔽或金属套之间的额定工频电压;
3、U—电缆设计用的导体之间的额定工频电压;
4、Um设备可承受的“最高系统电压”的最大值。
5、三相系统用电缆的U0值,推荐如下表:
1、The rated voltage of the cables shall be suitable for operation in cable system, using U0/U (Um) KV.
2、U0 cable design with the conductor and the shield or metal between the sets of rated voltage;
3、Rated power frequency voltage between U - for the design of the cable conductor;
4、Um equipment can withstand the "highest system voltage" maximum.
5、Three-phase system with cable U0, recommends the following table:
