Cable dimensioning with correction factors for current carrying capacity

Cables require trouble-free operation for decades, so cables must be carefully dimensioned and routed.

In order to ensure the safe operation of a cable, the following criteria for the correct design determine which cross-section is loadable up to which current:

  • Operating voltage
  • Permissible conductor temperature
  • Dynamic stress during short circuit
  • Short-circuit resistance
  • Cable / cable length
  • Maximum voltage drop
  • In which type of laying

Taking into account the above-mentioned criteria for the conductor dimensioning, the cable is not overloaded in any operating state.
