(3) The cross-section of the core must meet the requirements of the stability of the power supply system when short-circuited;

The selection of power cables should follow the following principles:

(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) The continuous allowable current of the cable should be equal to or greater than the maximum continuous current of the power supply load;

(3) The cross-section of the core must meet the requirements of the stability of the power supply system when short-circuited;

(4) Check whether the voltage drop meets the requirements according to the cable length;

(5) The minimum short-circuit current at the end of the line should enable the protection device to operate reliably.
