CYMCAP-MDB, Multiple Duct Banks
The Multiple Duct Banks module (MDB) is the extension to CYMCAP designed to determine the steady state ampacity of cables installed in several neighboring duct banks and/or backfills with different thermal resistivity. The module presents a unique solution combining standard and non-standard calculation methods. The module computes the values of T4 (the external to the cable thermal resistance) using finite elements and then the ampacity (or operating temperature) of the cable system is obtained using the IEC standardized solution method.

CYMCAP-MDB features many modeling facilities. The following capabilities can be highlighted:
- • Modeling up to eleven rectangular areas with different thermal
resistivity.
- • Modeling up to three duct banks in a single installation.
- • Modeling one heat source or sink in the installation.
- • Computation of the steady state ampacity or temperature.
