| （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 shall 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 permissible current of the cable shall be equal to or greater than the maximum permissible cumojuhdz.37ix.com.cnmojulys.37ix.com.cnresuomo.37ix.com.cnperesuomo.37ix.com.cnpvcmo.37ix.com.cn kongzhiqi.37ix.com.cnrrent 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) Core section should satisfy the stability requirement of power supply system in short circuit. （4）根据电缆长度验算电压降是否符合要求； (4) Check whether the voltage drop meets the requirements according to the length of the cable; （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 enable the protection device to operate reliably. |
