Now my query is: Has anybody worked out the derating factors for 2 layers/3 layers/random fill of cables in tray? Why is there a fundamental difference in cable laying conditions between IEC and NEC/NEMA world? Interestingly, IEC 60364-5-52 Sec. 523.3 says: The appropriate values of ...

The calculation principle is: Assuming that the cable ship moves forward in a certain period of time (ΔT) according to a uniform speed, direction to lay submarine cable, in the period of the time, the seabed terrain within the forward horizontal distance (ΔL) of the cable ship is known...
On the other hand, one of the important results of losses calculation and thermal analysis of cables is determination of life time.

Tray information is inputted to the setting program and overfilling is confirmed by applying the cable information to a tray (400). A tray layout drawing passing through an overfill calculation process is automatically outputted (500). If the tray receiving a cable is over, a route of the ...
