CYMCAP-OPT, Duct Bank Optimizer Module
The duct bank optimizer is an add-on module to CYMCAP that allows the user to determine the optimal placement of
several circuits within a duct bank.

More specifically, the module can recommend the various circuit disposition within the duct bank in order that:
- • The duct bank overall ampacity, i.e. the sum of the ampacities for all circuits, is maximized.
- • The duct bank overall ampacity, i.e. the sum of the ampacities for all circuits, is minimized.
- • The ampacity of any given circuit is maximized.
- • The ampacity of any given circuit is minimized.

For a 3 by 4 duct bank with three trefoils and one three-phase circuit (one phase per conduit), there are over
110,000 possible combinations. CYMCAP elaborated mathematical algorithm prevents the repetitive calculation of
equivalent cases, therefore the solution is obtained very efficiently. The condition illustrated on the right
hand side, below, shows the cable locations for maximum ampacity.
