(1)电缆的额定电压要大于或等于安装点供电系统的额定电压;
(1) the rated voltage of the cable should be greater than or equal to the rated voltage of the power supply system at the installation point.
(2)电缆持续容许电流应等于或大于供电负载的最大持续电流;
(2) the continuous permissible current of the cable should be equal to or greater than the maximum continuous current of the power supply load;
(3)线芯截面要满足供电系统短路时的稳定性的要求;
(3) the cross section of the wire core should meet the requirements of the stability of the power supply system short circuit.
(4)根据电缆长度验算电压降是否符合要求;
(4) checking the voltage drop according to the cable length is in line with the requirements.
(5)线路末端的最小短路电流应能使保护装置可靠的动作。
(5) the minimum short-circuit current at the end of the line should be able to make a reliable action of the protective device.
