咨询NHYJLV-4*70+1*35外径价格多少的详细介绍
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:
