max withstand current for a cable

[Hameedulla-Ekhlas]

Greeting to all,
I have calculated shortcircuit calculation using digsilent powerfactory software. I found in all buses and terminals the maximium kA as well as MVA.

Since I sized breakers and buses based on nominal and maximium kA as well as buses.

I have problem in Cable size. I have sized cables based on nominal ampere ampacity as well as voltage drop.

Is there any specific table for cables to understand the maximium short circuit that a cable can withstand for a few cycle like breakers or busbars.
