CYMCAP-CIT, Cables in Tunnels Module
The optional Cables in Tunnels Module allows the user to determine the temperature, steady state, cyclic and transient ampacity of cables installed in unventilated tunnels. Note that only equally loaded cables having the same type and loading are considered. This add-on module supports a large variety of cable arrangements for single core (flat formations or trefoils) and three-core cables. The cables can be laid down on a floor, hanging from supports clamped on a wall, installed in ladder racks or in cable trays.
